Lioncache: Document unknown input value for SetScreenShotPermission. Also place values in a table for nicer reading

AM (Applet Manager) provides services for interacting with system applets while abstracting several aspects of power and operation management.

Contains multiple raw images, with at least the following: "NN_OMM_CHARGING_BIN_{begin|end}"(charging icon), low-battery icon, and the Nintendo Switch logo displayed during system boot.

This is "nn::am::service::IAllSystemAppletProxiesService".

All of these commands except [[#OpenLibraryAppletProxy]] take the same input as [[#OpenApplicationProxy]], with the same user-process retry-loop as [[#OpenApplicationProxy]]. These Open*Proxy commands (including appletOE) doesn't seem to usable from processes which aren't actual applets (such as sysmodules), at least for applet-types which aren't already in use.

This service is used by all system non-regular-applications.

The 01000000000010XX system [[Title_list|titles]] use the following applet types(above Open{type}Proxy commands):
* "qlaunch": SystemApplet
* "overlay": OverlayApplet
* "starter": SystemApplication
* "maintenance": SystemApplet
* All others: LibraryApplet

== OpenLibraryAppletProxy ==
Returns an [[#ILibraryAppletProxy]].

Takes a [[IPC_Marshalling|reserved]] input u64(official user-processes use hard-coded value 0), a PID,a process copy-handle(cur-proc handle alias), and an 0x80-byte type-0x15 input buffer '''AppletAttribute'''.

Official user-processes use the same retry loop with this as the other Open*Proxy commands.

The BOTW game uses this GamePlayRecording functionality from the main-nso "nninitStartup" function, with size 0x6000000(96MiB). The official GamePlayRecording-enable code does the following(this will panic on any failure):
* [[SVC|Creates]] TransferMemory using the input buffer and size, with permissions=0.
* Uses [[#InitializeGamePlayRecording]] with the TransferMemory.
* Closes the TransferMemory handle, + TransferMemory cleanup.
* Uses [[#SetGamePlayRecordingState]] with value 0x1.
This GamePlayRecording functionality presumably enables the video-recording usable starting with [[4.0.0]].

==== PopLaunchParameter ====
Takes an input u32 [[#LaunchParameterKind]], returns an output [[#IStorage]].

Pops a LaunchParameter [[#IStorage]], the storage will be removed from sysmodule state during this.

==== CreateApplicationAndPushAndRequestToStart ====
Takes an input u64 titleID and an input [[#IStorage]], no output. titleID=0 can be used to relaunch the current application.

==== CreateApplicationAndPushAndRequestToStartForQuest ====
Takes 2 input u32s (loaded from struct [[#ApplicationAttributeForQuest]]), an input u64 titleID, and an input [[#IStorage]], no output.

==== CreateApplicationAndRequestToStart ====
Takes an input u64 titleID, no output.

Same as [[#CreateApplicationAndPushAndRequestToStart]] except without the input storage, official sw uses this when no input storage is specified.

==== CreateApplicationAndRequestToStartForQuest ====
Takes 2 input u32s (loaded from struct [[#ApplicationAttributeForQuest]]) and an input u64 titleID, no output.

Same as [[#CreateApplicationAndPushAndRequestToStartForQuest]] except without the input storage, official sw uses this when no input storage is specified.

==== CreateApplicationWithAttributeAndPushAndRequestToStartForQuest ====
Takes an input u64 titleID, a type-0x15 input buffer containing an [[#ApplicationAttribute]], an input [[#IStorage]], no output.

Same as [[#CreateApplicationAndPushAndRequestToStartForQuest]] except the entire attributes structure is directly specified via the input buffer. This command replaces [[#CreateApplicationAndPushAndRequestToStartForQuest]], official user-processes no longer use [[#CreateApplicationAndPushAndRequestToStartForQuest]].

==== CreateApplicationWithAttributeAndRequestToStartForQuest ====
Takes an input u64 titleID and a type-0x15 input buffer containing an [[#ApplicationAttribute]], no output.

Same as [[#CreateApplicationAndRequestToStartForQuest]] except the entire attributes structure is directly specified via the input buffer. This command replaces [[#CreateApplicationAndRequestToStartForQuest]], official user-processes no longer use [[#CreateApplicationAndPushAndRequestToStartForQuest]].

==== GetDesiredLanguage ====
No input, returns an output [[Settings_services#LanguageCode|LanguageCode]].

==== SetTerminateResult ====
Takes an input u32 '''Result''', no output.

For example, in some cases official apps use this with [[Error_codes|error]] 0x2A2 then uses svcBreak.

==== GetDisplayVersion ====
No input, returns an output 0x10-byte struct.

The output struct is "nn::oe::DisplayVersion". This the DisplayVersion string copied from the application [[NACP_Format|control.nacp]], this is always NUL-terminated.

==== EndBlockingHomeButtonShortAndLongPressed ====
No input/output.

==== BeginBlockingHomeButton ====
Takes an input s64 nanoseconds, no output. The input nanoseconds can be zero.

==== EndBlockingHomeButton ====
No input/output.

==== NotifyRunning ====
Takes no input. Returns an output u8 bool, which is ignored by official user-processes.

==== SetMediaPlaybackStateForApplication ====
Takes an input u8 bool, no output.

==== IsGamePlayRecordingSupported ====
No input, returns an output u8 bool.

==== InitializeGamePlayRecording ====
Takes a TransferMemory handle and an u64 for the size of the TransferMemory. The size must match 0x6000000 otherwise an error is returned.

==== SetGamePlayRecordingState ====
Takes an input u32. 0 = disable/pause, 1 = enable/restart.

==== RequestFlushGamePlayingMovieForDebug ====
No input/output.

==== RequestToShutdown ====
No input/output.

==== RequestToReboot ====
No input/output.

==== ExitAndRequestToShowThanksMessage ====
No input/output.

Used to exit the application and return to the kiosk menu. Official sw uses [[#UnlockExit]] immediately before this.

==== EnableApplicationCrashReport ====
Takes an input u8 bool, no output.

==== InitializeApplicationCopyrightFrameBuffer ====
Takes an input TransferMemory handle, an u32 '''width''', an u32 '''height''', an u64 tmem_size, and no output.

User-processes create the tmem with an user-specified buffer with permissions=0. '''width''' = 1280 and '''height''' = 720.

==== SetApplicationCopyrightImage ====
Takes a type-0x45 input buffer and 5 input s32s, no output.

The last s32 is "nn::oe::WindowOriginMode".

The first two s32s must not have the negative bit set, and the following two s32s must not be <1.

==== SetApplicationCopyrightVisibility ====
Takes an input u8 bool, no output.

==== QueryApplicationPlayStatistics ====
Takes a type-0x6 output buffer containing an array of [[Shared_Database_services|ApplicationPlayStatistics]] and a type-0x5 input buffer containing an array of u64 titleIDs. Returns an output s32 for actual total output entries.

The number of entries in each array is the same.

See also [[NACP_Format#PlayLogQueryCapability|PlayLogQueryCapability]].

This uses [[Shared_Database_services|pdm:qry]] QueryApplicationPlayStatisticsForSystem.

==== QueryApplicationPlayStatisticsByUid ====
Takes a u128 userID, a type-0x6 output buffer containing an array of [[Shared_Database_services|ApplicationPlayStatistics]] and a type-0x5 input buffer containing an array of u64 titleIDs. Returns an output s32 for actual total output entries.

Same as [[#QueryApplicationPlayStatistics]] except this uses [[Shared_Database_services|pdm:qry]] cmd16, to get playstats specific to userIDs.

==== ExecuteProgram ====
Takes an input u32 [[#ProgramSpecifyKind]] and an input u64, no output.

==== ClearUserChannel ====
No input/output.

Clears the UserChannel.

==== UnpopToUserChannel ====
Takes an input [[#IStorage]], no output.

The input storage is pushed to the UserChannel, which is also used by [[#ClearUserChannel]].

User-processes create a storage using data specified by the user (written to offset=0 size=inputsize), with max size 0x1000. This storage is then used with this cmd.

==== GetPreviousProgramIndex ====
No input, returns an output s32.

==== CreateMovieMaker ====
Takes an input u64 and handle, returns an [[#IMovieMaker]].

==== PrepareForJit ====
Takes no input. Launches title 010000000000003B (currently not present on retail systems) if some context variable is set.

=== CreateLibraryApplet ===
Takes 2 input u32s [[#AppletId]] and [[#LibraryAppletMode]], returns an [[#ILibraryAppletAccessor]].

=== TerminateAllLibraryApplets ===
No input/output.

=== AreAnyLibraryAppletsLeft ===
No input, returns an output u8 bool.

=== CreateStorage ===
Takes an input s64 for the storage size, returns an [[#IStorage]].

This allocates a buffer with the specified size which can then be accessed via [[#IStorageAccessor]].

=== CreateTransferMemoryStorage ===
Takes an input TransferMemory copy-handle, an input u8 bool, and an s64 size, returns an [[#IStorage]].

The user-process creates the TransferMemory with permissions=0.

The TransferMemory is mapped, which can then be accessed via [[#IStorageAccessor]]. The input bool controls whether writing to the storage is allowed: [[#Write]] will throw an error if this flag is not set.

=== CreateHandleStorage ===
Takes an input copy-handle and an input s64, returns an [[#IStorage]]. In some cases the s64 must not have the negative bit set.

The input can be arbitrary, however official sw is only (?) known to use this for TransferMemory (with s64=size).

Officially notification messages are handled by the application itself, not sdk-nso in ExeFS. Official apps call code in sdk-nso which basically uses svcWaitSynchronization with the event from [[#GetEventHandle]] to check whether a message is available, then if so it uses [[#ReceiveMessage]]. The actual handling for message IDs is done in the app itself(see [[#NotificationMessage]]).

[7.0.0+] User-processes now use BeginVrModeEx/EndVrModeEx instead of [[#SetVrModeEnabled]]. Prior to using using BeginVrModeEx, [[Parental_Control_services|pctl]] IsStereoVisionPermitted is used and error 0xD08E is thrown if not allowed by pctl.

=== GetEventHandle ===
No input. Returns an output event handle. This is signalled when a message is available with [[#ReceiveMessage]].

=== ReceiveMessage ===
No input. Returns an output u32. Error 0x680 indicates no message is available.

=== GetThisAppletKind ===
No input, returns an output [[#AppletKind]].

=== GetOperationMode ===
No input. Returns an output u8 for the current [[#OperationMode]].

=== GetPerformanceMode ===
No input. Returns an output u32 for the current PerformanceMode.

=== GetCradleStatus ===
No input, returns an output u8.

=== GetBootMode ===
No input, returns an output u8.

Returns the value from [[Process_Manager_services|pm:bm]] GetBootMode.

=== GetCurrentFocusState ===
No input. Returns an output u8:

* 1: In focus.
* 2/3: Out of focus(running in "background").

=== GetAcquiredSleepLockEvent ===
No input, returns an output handle.

=== PushToGeneralChannel ===
Takes an input [[#IStorage]], no output.

This is not usable under an Application, however it is usable under a LibraryApplet.

Used for sending requests to [[qlaunch]]. sdk-nso creates a 0x10-byte storage which is sent to this. The following are the functions which use this, with the data written to the storage:
* <code>RequestHomeMenu</code> <code>5341 4d53 0100 0000 0200 0000 0100 0000</code> Returns to the main Home Menu, equivalent to pressing the HOME button.
* <code>RequestJumpToSystemUpdate</code> <code>5341 4d53 0100 0000 0b00 0000 0100 0000</code> Equivalent to entering "System Update" under System Settings. When leaving this, it returns to the main Home Menu.

=== GetHomeButtonReaderLockAccessor ===
No input, returns an output [[#ILockAccessor]].

=== GetReaderLockAccessorEx ===
Takes an input u32, returns an output [[#ILockAccessor]].

=== GetWriterLockAccessorEx ===
Takes an input u32, returns an output [[#ILockAccessor]].

=== IsVrModeEnabled ===
No input, returns an output u8 bool.

=== SetVrModeEnabled ===
Takes an input u8 bool flag. No output.

Updates internal AM state fields. If the new state doesn't match the previous state, this uses the [[Backlight_services]] {Disable/Enable}VrMode command depending on whether flag={disable/enable}.

When the VrMode is set to true, the console shows a screen rendered like vr asking the user to move his face away and hit the 'close' button. When this button is pressed, the console resets the vrMode to false.

=== BeginVrModeEx ===
No input/output.

Identical to [[#SetVrModeEnabled]] except with hard-coded flag=1.

=== EndVrModeEx ===
No input/output.

Identical to [[#SetVrModeEnabled]] except with hard-coded flag=0.

=== IsInControllerFirmwareUpdateSection ===
No input, returns an output u8 bool.

=== GetDefaultDisplayResolutionChangeEvent ===
No input, returns an output handle.

=== SetCpuBoostMode ===
Takes an input u32 '''CpuBoostMode''' (only modes 0 and 1 are valid) and passes it to [[PPC_services#apm:sys|SetCpuBoostMode]].

=== SetPerformanceConfigurationChangedNotification ===
Takes an input u8 bool, no output.

=== GetCurrentPerformanceConfiguration ===
No input, returns the result of calling [[PPC_services#apm:sys|GetCurrentPerformanceConfiguration]].

=== GetOperationModeSystemInfo ===
No input, returns a total of 4-bytes of output.

=== Exit ===
No input/output.

=== LockExit ===
No input/output.

Locks exit process of pressing X to close in HOME Menu for an application or HOME button for an applet. When locked, it will show the "waiting for software to be closed dialog" until UnlockExit is called or a 15 seconds timeout (when the latter occurs, the process is force-terminated).

=== UnlockExit ===
No input/output.

Unlocks exit process, if LockExit was previously used.

=== EnterFatalSection ===
No input/output.

=== LeaveFatalSection ===
No input/output.

[[#EnterFatalSection]] must be executed at least once before executing this command, otherwise error code 0x40080 will be returned. EnterFatalSection and LeaveFatalSection work in pairs, that is, N calls to EnterFatalSection must be performed first in order to perform N executions of LeaveFatalSection. Essentially, these two functions operate like how one would lock and unlock a recursive mutex.

=== GetLibraryAppletLaunchableEvent ===
No input, returns an output event handle with autoclear=false.

=== SetScreenShotPermission ===
Takes an input s32. No output.

Controls whether screenshot-capture is allowed.

'''SetShimLibraryVersion''' is a wrapper for [[Capture_services|caps:c]] cmd33. Commands '''SaveScreenShot''', '''SaveScreenShotEx0''', '''SaveScreenShotEx1''' and '''SaveScreenShotEx2''' are wrappers for [[Display_services|caps:sc]] cmd210.

== SaveScreenShot ==
Takes two input u32s, an u64 AppletResourceUserId, a PID, and a type-0x45 input buffer. Returns a 0x20-byte struct '''ApplicationAlbumEntry'''.

Official user-processes doesn't use this, instead [[#SaveScreenShotEx0]] is used: ScreenShotAttributeEx0 is all-zero except +0 is set to an input u32.

== SaveScreenShotEx0 ==
Takes an input 0x40-byte struct '''ScreenShotAttributeEx0''', an input u32, an input u64 AppletResourceUserId, a PID, and a type-0x45 input buffer. Returns a 0x20-byte struct '''ApplicationAlbumEntry'''.

= Library Applets =
This section documents library applet launching.

Before starting the applet, [[#IStorage]]s are [[#ILibraryAppletCreator|created]] and written, then passed to [[#ILibraryAppletAccessor]] PushInData. The [[#IStorage]] session is closed afterwards. The first [[#IStorage]] is [[#CommonArguments]], followed by any applet-specific [[#IStorage]]s.

Once the applet finishes running successfully, [[#ILibraryAppletAccessor]] PopOutData can be used to get the applet-specific [[#IStorage]] containing the applet output data.

== CommonArguments ==
The first [[#CreateStorage|IStorage]] passed to applets should contain the common library applet arguments. This is populated by <code>nn::la::CommonArgumentsWriter</code> and has the following format.

This struct is 0x20-bytes.

Official sw handles the first 8-bytes separately, which is a header. With CommonArguments version 0x0, the header is 4-bytes, while starting with version 0x1 it's 8-bytes.

== Mapping restrictions ==
The physaddr range 0x80060000-0x2000000000 is not allowed to be mapped as IO.
The physaddr range 0x80000000-0x2000000000 is not allowed to be mapped as Normal.

[2.0.0-4.1.0] The range for IO was changed into 0x80060000-0x81D3FFFF.

[2.0.0-4.1.0] A blacklist was added for IO and Normal mappings:
* 0x50040000-0x50060000 (ARM, Interrupt Controller)
* 0x6000F000 (Exception Vectors)
* 0x6001DC00-0x6001E000 (IPATCH)
* 0x7000E000 (RTC/PMC)
* 0x70019000 (MC)
* 0x7001C000 (MC0)
* 0x7001D000 (MC1)

[5.0.0+] For IO, this blacklist was abandoned and instead two range checks were added. For Normal mappings it is still applied

{| class="wikitable" border="1"
|-
! Value || Description
|-
| 1 || Unknown
|-
| 2 || UART
|-
| 4 || UART when sleeping
|-
| 0xFFFF || Log to all destinations
|}

This is "nn::lm::ILogGetter".

{| class="wikitable" border="1"
|-
! Cmd || Name
|-
| 0 || StartLogging
|-

Log services

Lioncache: Rename ILogger command 0 from Initialize to Log. I doubt the original service name is Initialize, and this is more in line with what the actual function does; given this is used heavily by some games to fire out debug info.

= lm =
This is "nn::lm::ILogService".

Error codes

2019-05-07T23:42:24Z

Lioncache: Add BCAT error codes for failed data verification and non-existent passphrases.

= Structure =
These have been redesigned from the 3DS so that they fit within a Aarch64 MOV instruction immediate most of the time (without requiring the additional MOVK).

{| class=wikitable
! Bits || Field
|-
| 8-0 || Module
|-
| 21-9 || Description
|}

When a fatal-error is received the error code is outputted using the following formatter:
%04d-%04d

.. where the first code is <code>2000 + Module</code>, and the other being <code>Description</code>. Bits >=22 from the error-code are unused when displaying fatal-errors, since the Description ends with bit21.

When a fatal-error is received the error code is outputted using the following formatter:
%04d-%04d

.. where the first code is <code>2000 + Module</code>, and the other being <code>Description</code>. Bits >=22 from the error-code are unused when displaying fatal-errors, since the Description ends with bit21.

When a fatal-error is received the error code is outputted using the following formatter:
%04d-%04d

.. where the first code is <code>2000 + Module</code>, and the other being <code>Description</code>. Bits >=22 from the error-code are unused when displaying fatal-errors, since the Description ends with bit21.

When a fatal-error is received the error code is outputted using the following formatter:
%04d-%04d

.. where the first code is <code>2000 + Module</code>, and the other being <code>Description</code>. Bits >=22 from the error-code are unused when displaying fatal-errors, since the Description ends with bit21.

Error codes

2019-05-07T18:28:11Z

Lioncache: Add a few BCAT error code values. These values are currently in use as of 8.0.0 (and earlier as well).

= Structure =
These have been redesigned from the 3DS so that they fit within a Aarch64 MOV instruction immediate most of the time (without requiring the additional MOVK).

When a fatal-error is received the error code is outputted using the following formatter:
%04d-%04d

.. where the first code is <code>2000 + Module</code>, and the other being <code>Description</code>. Bits >=22 from the error-code are unused when displaying fatal-errors, since the Description ends with bit21.

When a fatal-error is received the error code is outputted using the following formatter:
%04d-%04d

.. where the first code is <code>2000 + Module</code>, and the other being <code>Description</code>. Bits >=22 from the error-code are unused when displaying fatal-errors, since the Description ends with bit21.

'''Description:''' Set the process heap to a given Size. It can both extend and shrink the heap.

Size must be a multiple of 0x200000 (2MB).

On success, the heap base-address (which is fixed by kernel, aslr'd) is written to OutAddr.

Uses current process pool partition.

[2.0.0+] Size must be less than or equal to 4GB.

</div>

'''Description:''' Change attribute of page-aligned memory region.

This is used to turn on/off caching for a given memory area. Useful when talking to devices such as the GPU.

What happens "under the hood" is the "Memory Attribute Indirection Register" index is changed from 2 to 3 in the MMU descriptor.

|}
</div>

'''Description:''' Maps a memory range into a different range.

Mainly used for adding guard pages around stack.

Source range gets reprotected to --- (it can no longer be accessed), and bit0 is set in the source [[#MemoryAttribute]].

[1.0.0] This could be used to map into either the Alias Region or the Stack region.

[2.0.0+] This can only be used to map into the Stack region.

Code can get the range of the Alias region from [[#svcGetInfo]] id0=2,3, and on 2.0.0+ the range of the Stack region via [[#svcGetInfo]] id0=14, 15 (on 1.0.0, the Stack region had hardcoded limits).

When mapped into the Alias region, the mapped memory will have state 0x482907.

When mapped into the Stack region, the mapped memory will have state 0x5C3C0B.

'''Description:''' Unmaps a region that was previously mapped with [[#svcMapMemory]].

It's possible to unmap ranges partially, you don't need to unmap the entire range "in one go".

The srcaddr/dstaddr must match what was given when the pages were originally mapped.

Works with num_handles <= 0x40.

When zero handles are passed, this will wait forever until either timeout or cancellation occurs.

Does not accept 0xFFFF8001 or 0xFFFF8000 as handles.

=== Object types ===

'''KDebug:''' signals when there is a new [[#DebugEventInfo|DebugEvent]] (retrievable via [[#svcGetDebugEvent]]).

'''KClientPort:''' signals when the number of sessions is less than the maximum allowed.

'''KProcess:''' signals when the process undergoes a state change (retrievable via [[#svcGetProcessInfo]]).

'''KReadableEvent:''' signals when the event's corresponding KWritableEvent has been signaled via svcSignalEvent.

'''KServerPort:''' signals when there is an incoming connection waiting to be [[#svcAcceptSession|accepted]].

'''KServerSession:''' signals when there is an incoming message waiting to be [[#svcReplyAndReceive|received]] or the pipe is closed.

'''KThread:''' signals when the thread has exited.

=== Result codes ===

'''0x0:''' Success. One of the objects was signaled before the timeout expired, or one of the objects is a Session with a closed remote. Handle index is updated to indicate which object signaled.

'''0x7601:''' Thread termination requested. Handle index is not updated.

'''0xe401:''' Invalid handle. Returned when one of the handles passed is invalid. Handle index is not updated.

'''0xe601:''' Invalid address. Returned when the handles pointer is not a readable address. Handle index is not updated.

'''0xea01:''' Timeout. Returned when no objects have been signaled within the timeout. Handle index is not updated.

'''0xec01:''' Interrupted. Returned when another thread uses [[#svcCancelSynchronization]] to cancel this thread. Handle index is not updated.

'''0xee01:''' Too many handles. Returned when the number of handles passed is > 0x40.

If the referenced thread is currently in a synchronization call ([[#svcWaitSynchronization]], [[#svcReplyAndReceive]] or [[#svcReplyAndReceiveLight]]), that call will be interrupted and return 0xec01.
If that thread is not currently executing such a synchronization call, the next call to a synchronization call will return 0xec01.

This doesn't take force-pause (activity/debug pause) into account.

=== Result codes ===

'''0x0:''' Success. The thread was either interrupted or has had its flag set.

'''0xe401:''' Invalid handle. The handle given was either invalid or not a thread handle.

If the process is attached, report the Break event. Then, if svcContinueDebugEvent didn't apply IgnoreException on the thread: if TPIDR_EL0 is 0, adjust ELR_EL1 to retry to svc instruction (and set TPIDR_EL0 to 1).

Otherwise, if bit31 in reason isn't set, perform crash reporting (see Exception Handling section below), if it doesn't terminate the process adjust ELR_EL1 as well.

Otherwise just return 0.

If ReplyTarget is not zero, a reply from the TLS will be sent to that session.
Then it will wait until either of the passed sessions has an incoming message, is closed, a passed port has an incoming connection, or the timeout expires.
If there is an incoming message, it is copied to the TLS.

If ReplyTarget is zero, the TLS should contain a blank message. If this message has a C descriptor, the buffer it points to will be used as the pointer buffer. See [[IPC_Marshalling#IPC_buffers]]. Note that a pointer buffer cannot be specified if ReplyTarget is not zero.

After being validated, passed handles will be enumerated in order; even if a session has been closed, if one that appears earlier in the list has an incoming message, it will take priority and a result code of 0x0 will be returned.

=== Result codes ===

'''0x0:''' Success. Either a session has an incoming message or a port has an incoming connection. HandleIndex is set appropriately.

'''0xea01:''' Timeout. No handles were signalled before the timeout expired. HandleIndex is not updated.

'''0xf601:''' Port remote dead. One of the sessions has been closed. HandleIndex is set appropriately.

== svcMapPhysicalMemoryUnsafe ==
Same as [[#svcMapPhysicalMemory]] except it always uses pool partition 0.

== svcCreateCodeMemory ==
Takes an address range with backing memory to create the code memory object.

The memory is initially memset to 0xFF after being locked.

== svcControlCodeMemory ==
Maps the backing memory for a Code memory object into the current process.

For [[#CodeMemoryOperation|CodeMemoryOperation_MapOwner]], memory permission must be RW-.

For [[#CodeMemoryOperation|CodeMemoryOperation_MapSlave]], memory permission must be R-- or R-X.

Operations [[#CodeMemoryOperation|CodeMemoryOperation_UnmapOwner/CodeMemoryOperation_UnmapSlave]] unmap memory that was previously mapped this way.

This allows one "secure JIT" process to map the code memory as RW-, and the other "slave" process to map it R-X.

[5.0.0+] Error 0xE401 is now returned when the process owner of the Code memory object is the same as the current process.

Read/write IO registers with a hardcoded whitelist. Input address is physical-address and must be aligned to 4.

rw_mask is 0 for reading and 0xffffffff for writing. You can also write individual bits by using a mask value.

You can only write to registers inside physical pages 0x70019000 (MC), 0x7001C000 (MC0), 0x7001D000 (MC1), and they all share the same whitelist.

The whitelist is same for writing as for reading.

The whitelist is:

0x054, 0x090, 0x094, 0x098, 0x09c, 0x0a0, 0x0a4, 0x0a8, 0x0ac, 0x0b0, 0x0b4, 0x0b8, 0x0bc, 0x0c0, 0x0c4, 0x0c8, 0x0d0, 0x0d4, 0x0d8, 0x0dc, 0x0e0, 0x100, 0x108, 0x10c, 0x118, 0x11c, 0x124, 0x128, 0x12c, 0x130, 0x134, 0x138, 0x13c, 0x158, 0x15c, 0x164, 0x168, 0x16c, 0x170, 0x174, 0x178, 0x17c, 0x200, 0x204, 0x2e4, 0x2e8, 0x2ec, 0x2f4, 0x2f8, 0x310, 0x314, 0x320, 0x328, 0x344, 0x348, 0x370, 0x374, 0x37c, 0x380, 0x390, 0x394, 0x398, 0x3ac, 0x3b8, 0x3bc, 0x3c0, 0x3c4, 0x3d8, 0x3e8, 0x41c, 0x420, 0x424, 0x428, 0x42c, 0x430, 0x44c, 0x47c, 0x480, 0x484, 0x50c, 0x554, 0x558, 0x55c, 0x670, 0x674, 0x690, 0x694, 0x698, 0x69c, 0x6a0, 0x6a4, 0x6c0, 0x6c4, 0x6f0, 0x6f4, 0x960, 0x970, 0x974, 0xa20, 0xa24, 0xb88, 0xb8c, 0xbc4, 0xbc8, 0xbcc, 0xbd0, 0xbd4, 0xbd8, 0xbdc, 0xbe0, 0xbe4, 0xbe8, 0xbec, 0xc00, 0xc5c, 0xcac

[2.0.0+] Whitelist was extended with 0x4c4, 0x4c8, 0x4cc, 0x584, 0x588, 0x58c.

[2.0.0+] The IO registers in range 0x7000E400 (PMC) size 0xC00 skip the whitelist, and do a TrustZone call using [[SMC]] Id1 0xC3000008(ReadWriteRegister).

[4.0.0+] Access to the Memory Controller (0x70019000) also uses smcReadWriteRegister.

Here is the whitelist imposed by that SMC, relative to the start of the PMC registers:

</div>

Sets one of the AArch64 hardware breakpoints. The nintendo switch has 6 hardware breakpoints, and 4 hardware watchpoints. The syscall has two behaviors depending on the value of hardware_breakpoint_id:

If hardware_breakpoint_id < 0x10, then it sets one of the AArch64 hardware breakpoints. Flags will go to DBGBCRn_EL1, and value to DBGBVRn_EL1. The only flags the user is allowed to set are those in the bitmask 0x7F01E1. Furthermore, the kernel will or it with 0x4004, in order to set various security flags to guarantee the watchpoints only triggers for code in EL0. If the user asks for a Breakpoint Type of ContextIDR match, the kernel shall use the given debug_handle to set DBGBVRn_EL1 to the ContextID of the debugged process.

If hardware_breakpoint_id is between 0x10 and 0x20 (exclusive), then it sets one of the AArch64 hardware watchpoints. Flags will go to DBGWCRn_EL1, and the value to DBGWVRn_EL1. The only flags the user is allowed to set are those in the bitmask 0xFF0F1FF9. Furthermore, the kernel will or it with 0x104004. This will set various security flags, and set the watchpoint type to be a Linked Watchpoint. This means that you need to link it to a Linked ContextIDR breakpoint. Check the ARM documentation for more information.

Note that hardware_breakpoint_id 0 to 4 match only to Virtual Address, while hardware_breakpoint_id 5 and 6 match against either Virtual Address, ContextID, or VMID. As such, if you are configuring a breakpoint to link for a watchpoint, make sure you use hardware_breakpoint_id 5 or 6.

For more documentation for hardware breakpoints, check out the AArch64 documentation for the [http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.ddi0488h/way1382455558968.html DBGBCRn_EL1 register] and the [http://infocenter.arm.com/help/topic/com.arm.doc.ddi0488h/way1382455560629.html DBGWCRn_EL1 register]

On [5.0.0] PoolPartition is specified in CreateProcessArgs. There are now 4 pool partitions.

On [5.0.0] (maybe lower?) a zero ResourceLimitHandle defaults to sysmodule limits and 0x12300000 bytes of memory.

The PersonalMmHeap are allocated as follows:
* For the application, normal insecure pool is used. Carveout 5 is used to provide protection.
* For the applet, a pre-allocated secure pool segment of size 0x400000 is used.
* For sysmodules, secure pool is allocated.

= Exception handling =
First of all, a function that might be called by synchronous exception handler and that is called by the SError handler fetches the exception info, adjusts PC, panics on exceptions taken from EL1, then dispatches the exception.

The dispatcher has two mutually exclusive exception reporting methods:
* by storing information at the start of the process's TLS memregion (TPIDRRO_EL0) and jumping back to the crt0
* by using KDebug

KDebug dispatching is used when at least one of the following conditions are met:
* SMC ConfigItem KernelMemConfig bit 1 is NOT set (it isn't on retail), unless: this is a software or hardware breakpoint, or a watchpoint, or [4.0.0+?] the process is attached and this is a Google PNaCl trap instruction (see LLVM source)
* FAR doesn't point to a valid address in mapped-readable CodeStatic memory (i.e. this is the case for NRO and JIT memory) or this is one of the following exceptions (it particular, that doesn't include FP exceptions occurring in CodeStatic memory):
** Uncategorized
** IllegalState
** SupervisorCallA32
** SupervisorCallA64
** PCAlignment
** SPAlignment
** SError
** BreakpointLowerEl
** SoftwareStepLowerEl (note: no way set single-step flag; not parsed)
** WatchpointLowerEl
** SoftwareBreakpointA32 (note: not parsed)
** SoftwareBreakpointA64 (note: not parsed)

In all other cases the userland-handled exception path is taken.

KDebug path:

If the process is attached, the exception is reported to the KDebug. If the thread was continued using flag IgnoreExceptions, it returns from the exception as if nothing happened.

If the latter is not the case, or if the process isn't attached, proceed to [2.0.0+] crash reporting (or in [1.0.0] just terminate the process):
if EnableDebug is set, and depending on the process state (more than one crash per process isn't permitted) it may signal itself with ProcessState_Crashed so that PM asks NS to start creport so that creport attaches to it and reports the crashes. Otherwise, just terminate.

Userland reporting path and svcReturnFromException:

In that case, after storing the regs in the TLS, the exception handler returns to the application's crt0 (entrypoint), with X0=<error description code> (see below) and X1=SP=frame=<stack top> (see above)

|-
|}

(During normal app boot the process is invoked with X0=0 and X1=main_thread_handle. The crt0 of retail apps determines whether to boot normally or handle an exception if X0 is set to 0 or not)

The application is supposed to promptly update the contents of elr_el1 to a user handler (and any other regs it sees fit) and call svcReturnFromException (error code) to call that handler. The latter is then expected to promptly abort the program.

svcReturnFromException updates the contents of the kernel stack frame with what the user provided in the TLS structure, sets TPIDR_EL0 to 1, then:
* if the provided error code is 0, gracefully pivots and returns from exception
* if it is not, replays the exception and pass it to the KDebug (see above). One can pass 0x10001 to prevent process termination. If the process is attached, this also prevents crash-collection/termination (different from the exception handler behavior)

If an exception occurs from the above user handler, the entire exception handling process will repeat with the new exception.

Note that if a thread that wasn't faulting calls svcReturnFromException, it signals an "invalid syscall" exception

Note that [[SMC|IsDebugMode]] is not used during exception-handling, except for enabling printing a message to UART-A. This UART code causes a system-hang on retail (likely due to a loop that doesn't exit). This printing doesn't seem to run when the process is attached for debugging?

Lioncache: Add kernel error codes related to invalid thread IDs in debug related supervisor calls.

These have been redesigned from the 3DS so that they fit within a Aarch64 MOV instruction immediate most of the time (without requiring the additional MOVK).

When a fatal-error is received the error code is outputted using the following formatter:
%04d-%04d

.. where the first code is <code>2000 + Module</code>, and the other being <code>Description</code>. Bits >=22 from the error-code are unused when displaying fatal-errors, since the Description ends with bit21.

'''Description:''' Set the process heap to a given Size. It can both extend and shrink the heap.

Size must be a multiple of 0x200000 (2MB).

On success, the heap base-address (which is fixed by kernel, aslr'd) is written to OutAddr.

Uses current process pool partition.

[2.0.0+] Size must be less than or equal to 4GB.

'''Description:''' Change attribute of page-aligned memory region.

This is used to turn on/off caching for a given memory area. Useful when talking to devices such as the GPU.

What happens "under the hood" is the "Memory Attribute Indirection Register" index is changed from 2 to 3 in the MMU descriptor.

</div>

'''Description:''' Maps a memory range into a different range.

Mainly used for adding guard pages around stack.

Source range gets reprotected to --- (it can no longer be accessed), and bit0 is set in the source [[#MemoryAttribute]].

[1.0.0] This could be used to map into either the Alias Region or the Stack region.

[2.0.0+] This can only be used to map into the Stack region.

Code can get the range of the Alias region from [[#svcGetInfo]] id0=2,3, and on 2.0.0+ the range of the Stack region via [[#svcGetInfo]] id0=14, 15 (on 1.0.0, the Stack region had hardcoded limits).

When mapped into the Alias region, the mapped memory will have state 0x482907.

When mapped into the Stack region, the mapped memory will have state 0x5C3C0B.

'''Description:''' Unmaps a region that was previously mapped with [[#svcMapMemory]].

It's possible to unmap ranges partially, you don't need to unmap the entire range "in one go".

The srcaddr/dstaddr must match what was given when the pages were originally mapped.

Works with num_handles <= 0x40.

When zero handles are passed, this will wait forever until either timeout or cancellation occurs.

Does not accept 0xFFFF8001 or 0xFFFF8000 as handles.

=== Object types ===

'''KDebug:''' signals when there is a new [[#DebugEventInfo|DebugEvent]] (retrievable via [[#svcGetDebugEvent]]).

'''KClientPort:''' signals when the number of sessions is less than the maximum allowed.

'''KProcess:''' signals when the process undergoes a state change (retrievable via [[#svcGetProcessInfo]]).

'''KReadableEvent:''' signals when the event's corresponding KWritableEvent has been signaled via svcSignalEvent.

'''KServerPort:''' signals when there is an incoming connection waiting to be [[#svcAcceptSession|accepted]].

'''KServerSession:''' signals when there is an incoming message waiting to be [[#svcReplyAndReceive|received]] or the pipe is closed.

'''KThread:''' signals when the thread has exited.

=== Result codes ===

'''0x0:''' Success. One of the objects was signaled before the timeout expired, or one of the objects is a Session with a closed remote. Handle index is updated to indicate which object signaled.

'''0x7601:''' Thread termination requested. Handle index is not updated.

'''0xe401:''' Invalid handle. Returned when one of the handles passed is invalid. Handle index is not updated.

'''0xe601:''' Invalid address. Returned when the handles pointer is not a readable address. Handle index is not updated.

'''0xea01:''' Timeout. Returned when no objects have been signaled within the timeout. Handle index is not updated.

'''0xec01:''' Interrupted. Returned when another thread uses [[#svcCancelSynchronization]] to cancel this thread. Handle index is not updated.

'''0xee01:''' Too many handles. Returned when the number of handles passed is > 0x40.

If the referenced thread is currently in a synchronization call ([[#svcWaitSynchronization]], [[#svcReplyAndReceive]] or [[#svcReplyAndReceiveLight]]), that call will be interrupted and return 0xec01.
If that thread is not currently executing such a synchronization call, the next call to a synchronization call will return 0xec01.

This doesn't take force-pause (activity/debug pause) into account.

=== Result codes ===

'''0x0:''' Success. The thread was either interrupted or has had its flag set.

'''0xe401:''' Invalid handle. The handle given was either invalid or not a thread handle.

If the process is attached, report the Break event. Then, if svcContinueDebugEvent didn't apply IgnoreException on the thread: if TPIDR_EL0 is 0, adjust ELR_EL1 to retry to svc instruction (and set TPIDR_EL0 to 1).

Otherwise, if bit31 in reason isn't set, perform crash reporting (see Exception Handling section below), if it doesn't terminate the process adjust ELR_EL1 as well.

Otherwise just return 0.

If ReplyTarget is not zero, a reply from the TLS will be sent to that session.
Then it will wait until either of the passed sessions has an incoming message, is closed, a passed port has an incoming connection, or the timeout expires.
If there is an incoming message, it is copied to the TLS.

If ReplyTarget is zero, the TLS should contain a blank message. If this message has a C descriptor, the buffer it points to will be used as the pointer buffer. See [[IPC_Marshalling#IPC_buffers]]. Note that a pointer buffer cannot be specified if ReplyTarget is not zero.

After being validated, passed handles will be enumerated in order; even if a session has been closed, if one that appears earlier in the list has an incoming message, it will take priority and a result code of 0x0 will be returned.

=== Result codes ===

'''0x0:''' Success. Either a session has an incoming message or a port has an incoming connection. HandleIndex is set appropriately.

'''0xea01:''' Timeout. No handles were signalled before the timeout expired. HandleIndex is not updated.

'''0xf601:''' Port remote dead. One of the sessions has been closed. HandleIndex is set appropriately.

== svcMapPhysicalMemoryUnsafe ==
Same as [[#svcMapPhysicalMemory]] except it always uses pool partition 0.

== svcCreateCodeMemory ==
Takes an address range with backing memory to create the code memory object.

The memory is initially memset to 0xFF after being locked.

== svcControlCodeMemory ==
Maps the backing memory for a Code memory object into the current process.

For [[#CodeMemoryOperation|CodeMemoryOperation_MapOwner]], memory permission must be RW-.

For [[#CodeMemoryOperation|CodeMemoryOperation_MapSlave]], memory permission must be R-- or R-X.

Operations [[#CodeMemoryOperation|CodeMemoryOperation_UnmapOwner/CodeMemoryOperation_UnmapSlave]] unmap memory that was previously mapped this way.

This allows one "secure JIT" process to map the code memory as RW-, and the other "slave" process to map it R-X.

[5.0.0+] Error 0xE401 is now returned when the process owner of the Code memory object is the same as the current process.

Read/write IO registers with a hardcoded whitelist. Input address is physical-address and must be aligned to 4.

rw_mask is 0 for reading and 0xffffffff for writing. You can also write individual bits by using a mask value.

You can only write to registers inside physical pages 0x70019000 (MC), 0x7001C000 (MC0), 0x7001D000 (MC1), and they all share the same whitelist.

The whitelist is same for writing as for reading.

The whitelist is:

0x054, 0x090, 0x094, 0x098, 0x09c, 0x0a0, 0x0a4, 0x0a8, 0x0ac, 0x0b0, 0x0b4, 0x0b8, 0x0bc, 0x0c0, 0x0c4, 0x0c8, 0x0d0, 0x0d4, 0x0d8, 0x0dc, 0x0e0, 0x100, 0x108, 0x10c, 0x118, 0x11c, 0x124, 0x128, 0x12c, 0x130, 0x134, 0x138, 0x13c, 0x158, 0x15c, 0x164, 0x168, 0x16c, 0x170, 0x174, 0x178, 0x17c, 0x200, 0x204, 0x2e4, 0x2e8, 0x2ec, 0x2f4, 0x2f8, 0x310, 0x314, 0x320, 0x328, 0x344, 0x348, 0x370, 0x374, 0x37c, 0x380, 0x390, 0x394, 0x398, 0x3ac, 0x3b8, 0x3bc, 0x3c0, 0x3c4, 0x3d8, 0x3e8, 0x41c, 0x420, 0x424, 0x428, 0x42c, 0x430, 0x44c, 0x47c, 0x480, 0x484, 0x50c, 0x554, 0x558, 0x55c, 0x670, 0x674, 0x690, 0x694, 0x698, 0x69c, 0x6a0, 0x6a4, 0x6c0, 0x6c4, 0x6f0, 0x6f4, 0x960, 0x970, 0x974, 0xa20, 0xa24, 0xb88, 0xb8c, 0xbc4, 0xbc8, 0xbcc, 0xbd0, 0xbd4, 0xbd8, 0xbdc, 0xbe0, 0xbe4, 0xbe8, 0xbec, 0xc00, 0xc5c, 0xcac

[2.0.0+] Whitelist was extended with 0x4c4, 0x4c8, 0x4cc, 0x584, 0x588, 0x58c.

[2.0.0+] The IO registers in range 0x7000E400 (PMC) size 0xC00 skip the whitelist, and do a TrustZone call using [[SMC]] Id1 0xC3000008(ReadWriteRegister).

[4.0.0+] Access to the Memory Controller (0x70019000) also uses smcReadWriteRegister.

Here is the whitelist imposed by that SMC, relative to the start of the PMC registers:

</div>

Sets one of the AArch64 hardware breakpoints. The nintendo switch has 6 hardware breakpoints, and 4 hardware watchpoints. The syscall has two behaviors depending on the value of hardware_breakpoint_id:

If hardware_breakpoint_id < 0x10, then it sets one of the AArch64 hardware breakpoints. Flags will go to DBGBCRn_EL1, and value to DBGBVRn_EL1. The only flags the user is allowed to set are those in the bitmask 0x7F01E1. Furthermore, the kernel will or it with 0x4004, in order to set various security flags to guarantee the watchpoints only triggers for code in EL0. If the user asks for a Breakpoint Type of ContextIDR match, the kernel shall use the given debug_handle to set DBGBVRn_EL1 to the ContextID of the debugged process.

If hardware_breakpoint_id is between 0x10 and 0x20 (exclusive), then it sets one of the AArch64 hardware watchpoints. Flags will go to DBGWCRn_EL1, and the value to DBGWVRn_EL1. The only flags the user is allowed to set are those in the bitmask 0xFF0F1FF9. Furthermore, the kernel will or it with 0x104004. This will set various security flags, and set the watchpoint type to be a Linked Watchpoint. This means that you need to link it to a Linked ContextIDR breakpoint. Check the ARM documentation for more information.

Note that hardware_breakpoint_id 0 to 4 match only to Virtual Address, while hardware_breakpoint_id 5 and 6 match against either Virtual Address, ContextID, or VMID. As such, if you are configuring a breakpoint to link for a watchpoint, make sure you use hardware_breakpoint_id 5 or 6.

For more documentation for hardware breakpoints, check out the AArch64 documentation for the [http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.ddi0488h/way1382455558968.html DBGBCRn_EL1 register] and the [http://infocenter.arm.com/help/topic/com.arm.doc.ddi0488h/way1382455560629.html DBGWCRn_EL1 register]

On [5.0.0] PoolPartition is specified in CreateProcessArgs. There are now 4 pool partitions.

On [5.0.0] (maybe lower?) a zero ResourceLimitHandle defaults to sysmodule limits and 0x12300000 bytes of memory.

The PersonalMmHeap are allocated as follows:
* For the application, normal insecure pool is used. Carveout 5 is used to provide protection.
* For the applet, a pre-allocated secure pool segment of size 0x400000 is used.
* For sysmodules, secure pool is allocated.

= Exception handling =
First of all, a function that might be called by synchronous exception handler and that is called by the SError handler fetches the exception info, adjusts PC, panics on exceptions taken from EL1, then dispatches the exception.

The dispatcher has two mutually exclusive exception reporting methods:
* by storing information at the start of the process's TLS memregion (TPIDRRO_EL0) and jumping back to the crt0
* by using KDebug

KDebug dispatching is used when at least one of the following conditions are met:
* SMC ConfigItem KernelMemConfig bit 1 is NOT set (it isn't on retail), unless: this is a software or hardware breakpoint, or a watchpoint, or [4.0.0+?] the process is attached and this is a Google PNaCl trap instruction (see LLVM source)
* FAR doesn't point to a valid address in mapped-readable CodeStatic memory (i.e. this is the case for NRO and JIT memory) or this is one of the following exceptions (it particular, that doesn't include FP exceptions occurring in CodeStatic memory):
** Uncategorized
** IllegalState
** SupervisorCallA32
** SupervisorCallA64
** PCAlignment
** SPAlignment
** SError
** BreakpointLowerEl
** SoftwareStepLowerEl (note: no way set single-step flag; not parsed)
** WatchpointLowerEl
** SoftwareBreakpointA32 (note: not parsed)
** SoftwareBreakpointA64 (note: not parsed)

In all other cases the userland-handled exception path is taken.

KDebug path:

If the process is attached, the exception is reported to the KDebug. If the thread was continued using flag IgnoreExceptions, it returns from the exception as if nothing happened.

If the latter is not the case, or if the process isn't attached, proceed to [2.0.0+] crash reporting (or in [1.0.0] just terminate the process):
if EnableDebug is set, and depending on the process state (more than one crash per process isn't permitted) it may signal itself with ProcessState_Crashed so that PM asks NS to start creport so that creport attaches to it and reports the crashes. Otherwise, just terminate.

Userland reporting path and svcReturnFromException:

{| class=wikitable
! Offset || Length || Description
|-
| 0x0 || 0x148 || Exception stack

TLS region start (A32):

{| class=wikitable
! Offset || Length || Description
|-
| 0x0 || 0x178 || Exception stack
|-
| 0x148 || 0x44 || ExceptionFrameA32

ExceptionFrameA32:

{| class=wikitable
! Offset || Length || Description
|-
| 0x0 || 0x20 (8*4) || GPRs 0..7.
|-
| 0x20 || 0x4 || sp
|-

|-
| 0x28 || 0x4 || pc (elr_el1)
|-
| 0x2C || 0x4 || tpidr_el0 = 1
|-
| 0x30 || 0x4 || cpsr & 0xFF0FFE20
|-
| 0x34 || 0x4 || afsr0
|-
| 0x38 || 0x4 || afsr1
|-
| 0x3C || 0x4 || esr
|-
| 0x40 || 0x4 || far
|}

In that case, after storing the regs in the TLS, the exception handler returns to the application's crt0 (entrypoint), with X0=<error description code> (see below) and X1=SP=frame=<stack top> (see above)

{| class=wikitable
! Desc. code || Meaning
|-
| 0x100 || Instruction abort
|-
| 0x102 || Misaligned PC
|-
| 0x103 || Misaligned SP
|-
| 0x106 || SError [not in 1.0.0?]
|-
| 0x301 || Bad SVC
|-
| 0x104 || Uncategorized, CP15RTTrap, CP15RRTTrap, CP14RTTrap, CP14RRTTrap, IllegalState, SystemRegisterTrap
|-
| 0x101 || None of the above, EC <= 0x34 and not a breakpoint
|-
|}

(During normal app boot the process is invoked with X0=0 and X1=main_thread_handle. The crt0 of retail apps determines whether to boot normally or handle an exception if X0 is set to 0 or not)

The application is supposed to promptly update the contents of elr_el1 to a user handler (and any other regs it sees fit) and call svcReturnFromException (error code) to call that handler. The latter is then expected to promptly abort the program.

svcReturnFromException updates the contents of the kernel stack frame with what the user provided in the TLS structure, sets TPIDR_EL0 to 1, then:
* if the provided error code is 0, gracefully pivots and returns from exception
* if it is not, replays the exception and pass it to the KDebug (see above). One can pass 0x10001 to prevent process termination. If the process is attached, this also prevents crash-collection/termination (different from the exception handler behavior)

If an exception occurs from the above user handler, the entire exception handling process will repeat with the new exception.

Note that if a thread that wasn't faulting calls svcReturnFromException, it signals an "invalid syscall" exception

Note that [[SMC|IsDebugMode]] is not used during exception-handling, except for enabling printing a message to UART-A. This UART code causes a system-hang on retail (likely due to a loop that doesn't exit). This printing doesn't seem to run when the process is attached for debugging?

Applet Manager services

Lioncache: Expand documentation about behavior of LeaveFatalSection

AM (Applet Manager) provides services for interacting with system applets while abstracting several aspects of power and operation management.

Contains multiple raw images, with at least the following: "NN_OMM_CHARGING_BIN_{begin|end}"(charging icon), low-battery icon, and the Nintendo Switch logo displayed during system boot.

All of these commands except [[#OpenLibraryAppletProxy]] take the same input as [[#OpenApplicationProxy]], with the same user-process retry-loop as [[#OpenApplicationProxy]]. These Open*Proxy commands (including appletOE) doesn't seem to usable from processes which aren't actual applets (such as sysmodules), at least for applet-types which aren't already in use.

This service is used by all system non-regular-applications.

The 01000000000010XX system [[Title_list|titles]] use the following applet types(above Open{type}Proxy commands):
* "qlaunch": SystemApplet
* "overlay": OverlayApplet
* "starter": SystemApplication
* "maintenance": SystemApplet
* All others: LibraryApplet

== OpenLibraryAppletProxy ==
Returns an [[#ILibraryAppletProxy]].

Takes a [[IPC_Marshalling|reserved]] input u64(official user-processes use hard-coded value 0), a PID,a process copy-handle(cur-proc handle alias), and an 0x80-byte type-0x15 input buffer '''AppletAttribute'''.

Official user-processes use the same retry loop with this as the other Open*Proxy commands.

The BOTW game uses this GamePlayRecording functionality from the main-nso "nninitStartup" function, with size 0x6000000(96MiB). The official GamePlayRecording-enable code does the following(this will panic on any failure):
* [[SVC|Creates]] TransferMemory using the input buffer and size, with permissions=0.
* Uses [[#InitializeGamePlayRecording]] with the TransferMemory.
* Closes the TransferMemory handle, + TransferMemory cleanup.
* Uses [[#SetGamePlayRecordingState]] with value 0x1.
This GamePlayRecording functionality presumably enables the video-recording usable starting with [[4.0.0]].

==== PopLaunchParameter ====
Takes an input u32 [[#LaunchParameterKind]], returns an output [[#IStorage]].

Pops a LaunchParameter [[#IStorage]], the storage will be removed from sysmodule state during this.

==== CreateApplicationAndPushAndRequestToStart ====
Takes an input u64 titleID and an input [[#IStorage]], no output. titleID=0 can be used to relaunch the current application.

==== CreateApplicationAndPushAndRequestToStartForQuest ====
Takes 2 input u32s (loaded from struct ApplicationAttributeForQuest), an input u64 titleID, and an input [[#IStorage]], no output.

==== CreateApplicationAndRequestToStart ====

==== SetApplicationCopyrightVisibility ====
Takes an input u8 bool, no output.

==== QueryApplicationPlayStatistics ====
Takes a type-0x6 output buffer containing an array of ApplicationPlayStatistics and a type-0x5 input buffer containing an array of u64 titleIDs. Returns an output s32 (actual total output entries?).

The number of entries in each array is the same. ApplicationPlayStatistics is a 8-byte struct.

=== TerminateAllLibraryApplets ===
No input/output.

=== AreAnyLibraryAppletsLeft ===
No input, returns an output u8 bool.

=== CreateStorage ===
Takes an input s64 for the storage size, returns an [[#IStorage]].

This allocates a buffer with the specified size which can then be accessed via [[#IStorageAccessor]].

=== CreateTransferMemoryStorage ===
Takes an input TransferMemory copy-handle, an input u8 bool, and an s64 size, returns an [[#IStorage]].

The user-process creates the TransferMemory with permissions=0.

The TransferMemory is mapped, which can then be accessed via [[#IStorageAccessor]]. The input bool controls whether writing to the storage is allowed: [[#Write]] will throw an error if this flag is not set.

=== CreateHandleStorage ===
Takes an input copy-handle and an input s64, returns an [[#IStorage]]. In some cases the s64 must not have the negative bit set.

The input can be arbitrary, however official sw is only (?) known to use this for TransferMemory (with s64=size).

Officially notification messages are handled by the application itself, not sdk-nso in ExeFS. Official apps call code in sdk-nso which basically uses svcWaitSynchronization with the event from [[#GetEventHandle]] to check whether a message is available, then if so it uses [[#ReceiveMessage]]. The actual handling for message IDs is done in the app itself(see [[#NotificationMessage]]).

=== GetEventHandle ===
No input. Returns an output event handle. This is signalled when a message is available with [[#ReceiveMessage]].

=== ReceiveMessage ===
No input. Returns an output u32. Error 0x680 indicates no message is available.

=== GetThisAppletKind ===
No input, returns an output [[#AppletKind]].

=== GetOperationMode ===
No input. Returns an output u8 for the current [[#OperationMode]].

=== GetPerformanceMode ===
No input. Returns an output u32 for the current PerformanceMode.

=== GetCradleStatus ===
No input, returns an output u8.

=== GetBootMode ===
No input, returns an output u8.

=== GetCurrentFocusState ===
No input. Returns an output u8:

* 1: In focus.
* 2/3: Out of focus(running in "background").

=== GetAcquiredSleepLockEvent ===
No input, returns an output handle.

=== PushToGeneralChannel ===
Takes an input [[#IStorage]], no output.

This is not usable under an Application, however it is usable under a LibraryApplet.

Used for sending requests to [[qlaunch]]. sdk-nso creates a 0x10-byte storage which is sent to this. The following are the functions which use this, with the data written to the storage:
* <code>RequestHomeMenu</code> <code>5341 4d53 0100 0000 0200 0000 0100 0000</code> Returns to the main Home Menu, equivalent to pressing the HOME button.
* <code>RequestJumpToSystemUpdate</code> <code>5341 4d53 0100 0000 0b00 0000 0100 0000</code> Equivalent to entering "System Update" under System Settings. When leaving this, it returns to the main Home Menu.

=== GetHomeButtonReaderLockAccessor ===
No input, returns an output [[#ILockAccessor]].

=== GetReaderLockAccessorEx ===
Takes an input u32, returns an output [[#ILockAccessor]].

=== IsVrModeEnabled ===
No input, returns an output u8 bool.

=== SetVrModeEnabled ===
Takes an input u8 bool flag. No output.

Updates internal AM state fields. If the new state doesn't match the previous state, this uses the [[Backlight_services]] {Disable/Enable}VrMode command depending on whether flag={disable/enable}.

When the VrMode is set to true, the console shows a screen rendered like vr asking the user to move his face away and hit the 'close' button. When this button is pressed, the console resets the vrMode to false.

=== IsInControllerFirmwareUpdateSection ===
No input, returns an output u8 bool.

=== GetDefaultDisplayResolutionChangeEvent ===
No input, returns an output handle.

=== Exit ===
No input/output.

=== LockExit ===
No input/output.

Locks exit process of pressing X to close in HOME Menu for an application or HOME button for an applet. When locked, it will show the "waiting for software to be closed dialog" until UnlockExit is called or a 15 seconds timeout (when the latter occurs, the process is force-terminated).

=== UnlockExit ===
No input/output.

Unlocks exit process, if LockExit was previously used.

=== EnterFatalSection ===
No input/output.

=== LeaveFatalSection ===
No input/output.

[[#EnterFatalSection]] must be executed at least once before executing this command, otherwise error code 0x40080 will be returned. EnterFatalSection and LeaveFatalSection work in pairs, that is, N calls to EnterFatalSection must be performed first in order to perform N executions of LeaveFatalSection. Essentially, these two functions operate like how one would lock and unlock a recursive mutex.

=== GetLibraryAppletLaunchableEvent ===
No input, returns an output event handle with autoclear=false.

=== SetScreenShotPermission ===
Takes an input s32. No output.

Controls whether screenshot-capture is allowed. 0 = disable, 1 = enable, 2 = unknown.

Cmd32 is a wrapper for [[Capture_services|caps:c]] cmd33. Commands 201, 203, and 210 are wrappers for [[Display_services|caps:sc]] cmd210.

== SaveScreenShot ==
Takes two input u32s, an u64 AppletResourceUserId, a PID, and a type-0x45 input buffer. Returns a 0x20-byte struct '''ApplicationAlbumEntry'''.

Official user-processes doesn't use this, instead [[#SaveScreenShotEx0]] is used: ScreenShotAttributeEx0 is all-zero except +0 is set to an input u32.

== SaveScreenShotEx0 ==
Takes an input 0x40-byte struct '''ScreenShotAttributeEx0''', an input u32, an input u64 AppletResourceUserId, a PID, and a type-0x45 input buffer. Returns a 0x20-byte struct '''ApplicationAlbumEntry'''.

= Library Applets =
This section documents library applet launching.

Before starting the applet, [[#IStorage]]s are [[#ILibraryAppletCreator|created]] and written, then passed to [[#ILibraryAppletAccessor]] PushInData. The [[#IStorage]] session is closed afterwards. The first [[#IStorage]] is [[#CommonArguments]], followed by any applet-specific [[#IStorage]]s.

Once the applet finishes running successfully, [[#ILibraryAppletAccessor]] PopOutData can be used to get the applet-specific [[#IStorage]] containing the applet output data.

== CommonArguments ==
The first [[#CreateStorage|IStorage]] passed to applets should contain the common library applet arguments. This is populated by <code>nn::la::CommonArgumentsWriter</code> and has the following format.

This struct is 0x20-bytes.

Official sw handles the first 8-bytes separately, which is a header. With CommonArguments version 0x0, the header is 4-bytes, while starting with version 0x1 it's 8-bytes.

When a fatal-error is received the error code is outputted using the following formatter:
%04d-%04d

.. where the first code is <code>2000 + Module</code>, and the other being <code>Description</code>. Bits >=22 from the error-code are unused when displaying fatal-errors, since the Description ends with bit21.

When this value is 0, gameplay cannot be recorded. When this value is 1, the game must manually sacrifice some of its heap as transfer memory for AM's IApplicationProxy->InitializeGamePlayRecording(). When this value is 2, AM will call NS->BoostSystemMemoryResourceSize(), and allocate the required memory for recording automatically without the usermode process having to do anything.

Applet Manager services

Lioncache: Document the remaining two LibraryAppletMode modes

AM (Applet Manager) provides services for interacting with system applets while abstracting several aspects of power and operation management.

Contains multiple raw images, with at least the following: "NN_OMM_CHARGING_BIN_{begin|end}"(charging icon), low-battery icon, and the Nintendo Switch logo displayed during system boot.

All of these commands except [[#OpenLibraryAppletProxy]] take the same input as [[#OpenApplicationProxy]], with the same user-process retry-loop as [[#OpenApplicationProxy]]. These Open*Proxy commands (including appletOE) doesn't seem to usable from processes which aren't actual applets (such as sysmodules), at least for applet-types which aren't already in use.

This service is used by all system non-regular-applications.

The 01000000000010XX system [[Title_list|titles]] use the following applet types(above Open{type}Proxy commands):
* "qlaunch": SystemApplet
* "overlay": OverlayApplet
* "starter": SystemApplication
* "maintenance": SystemApplet
* All others: LibraryApplet

== OpenLibraryAppletProxy ==
Returns an [[#ILibraryAppletProxy]].

Takes a [[IPC_Marshalling|reserved]] input u64(official user-processes use hard-coded value 0), a PID,a process copy-handle(cur-proc handle alias), and an 0x80-byte type-0x15 input buffer '''AppletAttribute'''.

Official user-processes use the same retry loop with this as the other Open*Proxy commands.

The BOTW game uses this GamePlayRecording functionality from the main-nso "nninitStartup" function, with size 0x6000000(96MiB). The official GamePlayRecording-enable code does the following(this will panic on any failure):
* [[SVC|Creates]] TransferMemory using the input buffer and size, with permissions=0.
* Uses [[#InitializeGamePlayRecording]] with the TransferMemory.
* Closes the TransferMemory handle, + TransferMemory cleanup.
* Uses [[#SetGamePlayRecordingState]] with value 0x1.
This GamePlayRecording functionality presumably enables the video-recording usable starting with [[4.0.0]].

==== PopLaunchParameter ====
Takes an input u32 [[#LaunchParameterKind]], returns an output [[#IStorage]].

Pops a LaunchParameter [[#IStorage]], the storage will be removed from sysmodule state during this.

==== CreateApplicationAndRequestToStartForQuest ====
Takes 2 input u32s (loaded from struct ApplicationAttributeForQuest) and an input u64 titleID, no output.

Same as [[#CreateApplicationAndPushAndRequestToStartForQuest]] except without the input storage, official sw uses this when no input storage is specified.

==== GetDesiredLanguage ====
No input, returns an output [[Settings_services#LanguageCode|LanguageCode]].

==== SetTerminateResult ====
Takes an input u32 '''Result''', no output.

For example, in some cases official apps use this with [[Error_codes|error]] 0x2A2 then uses svcBreak.

==== SetApplicationCopyrightVisibility ====
Takes an input u8 bool, no output.

==== QueryApplicationPlayStatistics ====
Takes a type-0x6 output buffer containing an array of ApplicationPlayStatistics and a type-0x5 input buffer containing an array of u64 titleIDs. Returns an output s32 (actual total output entries?).

The number of entries in each array is the same. ApplicationPlayStatistics is a 8-byte struct.

==== ClearUserChannel ====
No input/output.

==== CreateMovieMaker ====
Takes an input u64 and handle, returns an [[#IMovieMaker]].

==== PrepareForJit ====

=== TerminateAllLibraryApplets ===
No input/output.

=== AreAnyLibraryAppletsLeft ===
No input, returns an output u8 bool.

=== CreateStorage ===
Takes an input s64 for the storage size, returns an [[#IStorage]].

This allocates a buffer with the specified size which can then be accessed via [[#IStorageAccessor]].

=== CreateTransferMemoryStorage ===
Takes an input TransferMemory copy-handle, an input u8 bool, and an s64 size, returns an [[#IStorage]].

The user-process creates the TransferMemory with permissions=0.

The TransferMemory is mapped, which can then be accessed via [[#IStorageAccessor]]. The input bool controls whether writing to the storage is allowed: [[#Write]] will throw an error if this flag is not set.

=== CreateHandleStorage ===
Takes an input copy-handle and an input s64, returns an [[#IStorage]]. In some cases the s64 must not have the negative bit set.

The input can be arbitrary, however official sw is only (?) known to use this for TransferMemory (with s64=size).

Officially notification messages are handled by the application itself, not sdk-nso in ExeFS. Official apps call code in sdk-nso which basically uses svcWaitSynchronization with the event from [[#GetEventHandle]] to check whether a message is available, then if so it uses [[#ReceiveMessage]]. The actual handling for message IDs is done in the app itself(see [[#NotificationMessage]]).

=== GetEventHandle ===
No input. Returns an output event handle. This is signalled when a message is available with [[#ReceiveMessage]].

=== ReceiveMessage ===
No input. Returns an output u32. Error 0x680 indicates no message is available.

=== GetThisAppletKind ===
No input, returns an output [[#AppletKind]].

=== GetOperationMode ===
No input. Returns an output u8 for the current [[#OperationMode]].

=== GetPerformanceMode ===
No input. Returns an output u32 for the current PerformanceMode.

=== GetCradleStatus ===
No input, returns an output u8.

=== GetBootMode ===
No input, returns an output u8.

=== GetCurrentFocusState ===
No input. Returns an output u8:

* 1: In focus.
* 2/3: Out of focus(running in "background").

=== GetAcquiredSleepLockEvent ===
No input, returns an output handle.

=== PushToGeneralChannel ===
Takes an input [[#IStorage]], no output.

This is not usable under an Application, however it is usable under a LibraryApplet.

Used for sending requests to [[qlaunch]]. sdk-nso creates a 0x10-byte storage which is sent to this. The following are the functions which use this, with the data written to the storage:
* <code>RequestHomeMenu</code> <code>5341 4d53 0100 0000 0200 0000 0100 0000</code> Returns to the main Home Menu, equivalent to pressing the HOME button.
* <code>RequestJumpToSystemUpdate</code> <code>5341 4d53 0100 0000 0b00 0000 0100 0000</code> Equivalent to entering "System Update" under System Settings. When leaving this, it returns to the main Home Menu.

=== GetHomeButtonReaderLockAccessor ===
No input, returns an output [[#ILockAccessor]].

=== GetReaderLockAccessorEx ===
Takes an input u32, returns an output [[#ILockAccessor]].

=== IsVrModeEnabled ===
No input, returns an output u8 bool.

=== SetVrModeEnabled ===
Takes an input u8 bool flag. No output.

Updates internal AM state fields. If the new state doesn't match the previous state, this uses the [[Backlight_services]] {Disable/Enable}VrMode command depending on whether flag={disable/enable}.

When the VrMode is set to true, the console shows a screen rendered like vr asking the user to move his face away and hit the 'close' button. When this button is pressed, the console resets the vrMode to false.

=== IsInControllerFirmwareUpdateSection ===
No input, returns an output u8 bool.

=== GetDefaultDisplayResolutionChangeEvent ===
No input, returns an output handle.

Official user-processes doesn't use this, instead [[#SaveScreenShotEx0]] is used: ScreenShotAttributeEx0 is all-zero except +0 is set to an input u32.

== SaveScreenShotEx0 ==
Takes an input 0x40-byte struct '''ScreenShotAttributeEx0''', an input u32, an input u64 AppletResourceUserId, a PID, and a type-0x45 input buffer. Returns a 0x20-byte struct '''ApplicationAlbumEntry'''.

= Library Applets =
This section documents library applet launching.

Before starting the applet, [[#IStorage]]s are [[#ILibraryAppletCreator|created]] and written, then passed to [[#ILibraryAppletAccessor]] PushInData. The [[#IStorage]] session is closed afterwards. The first [[#IStorage]] is [[#CommonArguments]], followed by any applet-specific [[#IStorage]]s.

Once the applet finishes running successfully, [[#ILibraryAppletAccessor]] PopOutData can be used to get the applet-specific [[#IStorage]] containing the applet output data.

== CommonArguments ==
The first [[#CreateStorage|IStorage]] passed to applets should contain the common library applet arguments. This is populated by <code>nn::la::CommonArgumentsWriter</code> and has the following format.

This struct is 0x20-bytes.

Official sw handles the first 8-bytes separately, which is a header. With CommonArguments version 0x0, the header is 4-bytes, while starting with version 0x1 it's 8-bytes.

This uses Android code.

Command(s) from here are constantly used while displaying gfx.

TransactParcel is used by 1.0.0 official user-processes, while starting with 3.0.0 TransactParcelAuto is used instead.

For IHOSBinderDriver, the below '''ID''' is loaded from the layer's [[Display_services#NativeWindow]].

== TransactParcel ==
Takes a s32 ('''ID'''), an u32 ('''code'''), a type-0x5 input buffer ('''parcel_data'''), a type-0x6 output buffer ('''parcel_reply''') and an input u32 ('''flags'''). Each word is placed immediately after the previous word.

Analogous to "onTransact" from "android.os.IServiceManager".

== AdjustRefcount ==

Takes 3 input s32s: '''ID''', '''addval''', and '''type'''. Each word immediately follows the previous word. No additional output.

'''type''' indicates whether the strong reference count or weak reference count will be affected. 0 indicates the weak reference count, while 1 indicates the strong reference count.

|}

During init, {addval=1, type=0} is used then {addval=1, type=1} is used.

== GetNativeHandle ==
Takes an input s32 ('''ID''') and u32, with the latter immediately following the previous word. Returns an output event handle.

== TransactParcelAuto ==
Takes a s32 ('''ID'''), an u32 ('''code'''), a type-0x21 input buffer ('''parcel_data'''), a type-0x22 output buffer ('''parcel_reply''') and an input u32 ('''flags'''). Each word is placed immediately after the previous word.

Lioncache: Document unknown fields within DisplayInfo. These indicate if a display has a limited number of layers (and if so, how many layers are allowed).

The only image data contained in this sysmodule is basically a saved display framebuffer, no image data for actively-used layers/framebuffers.

== Cmd1 ==
Takes a type-0x46 output buffer, an input u32, two input u64s '''width'''/'''height''', an input s64 '''buffer_count''', and an input s64 '''buffer_index'''.

'''width'''/'''height''' must match 1280/720. '''buffer_index''' must be < '''buffer_count'''. '''buffer_index''' and '''buffer_count''' must not be negative.

'''buffer_index''' and '''buffer_count''' correspond to buffers with size 0x384000(1280*720*4).

Value 0 is usable for the input u32.

This takes a screenshot, the output buffer contains the RGBA8 image.

Available sessions for each service:
* "vi:u": Only GetRelayService.
* "vi:s": Everything except GetManagerDisplayService.
* "vi:m": All.

When attempting to use a get-session cmd with a service it's not available with, error 0xA72 is returned.

These commands using PIDs have AppletResourceUserId as the last input u64, hence AppletResourceUserId must [[IPC_Marshalling|match]] the user-process PID(no special handling for value 0).

== GetRelayService ==
Returns an [[Nvnflinger_services#dispdrv|IHOSBinderDriver]] interface which abstracts "nn::visrv::service::RelayServiceImpl".

== GetIndirectDisplayTransactionService ==
Returns an [[Nvnflinger_services#dispdrv|IHOSBinderDriver]] interface which abstracts "nn::visrv::service::IndirectDisplayTransactionServiceImpl".

== GetSystemDisplayService ==
Returns an [[#ISystemDisplayService]].

== GetManagerDisplayService ==
Returns an [[#IManagerDisplayService]].

== ListDisplays ==
Takes a type-0x6 output buffer containing the array of [[#DisplayInfo]] output entries. Returns an output u64: total number of output entries.

Normally(?) this only returns the "Default" display.

== OpenDisplay ==
Takes a [[#DisplayName]] as input. Returns an output u64, the DisplayId.

To open the default display, input string "Default" can be used.

== OpenDefaultDisplay ==
Returns an output u64.

Probably not (?) used by newer official user-processes, since those use OpenDisplay with the default string instead.

== CloseDisplay ==
Takes an input u64, DisplayId.

== SetDisplayEnabled ==
Takes an input u32 boolean, and an u64 DisplayId.

== GetDisplayResolution ==
Takes an input u64 DisplayId and returns two output u64s: width and height.

== OpenLayer ==
Takes a PID-descriptor, a type-0x6 buffer for the output [[#NativeWindow]], a [[#DisplayName]](which was previously used with [[#OpenDisplay]]), an u64 LayerId, and an u64 [[AM_services|AppletResourceUserId]]. Returns an output u64 NativeWindow_Size.

Official user-processes use a LayerId stored in a global state field("...ExternalLayerId") if non-zero, otherwise:
* When AppletResourceUserId==0, [[#CreateStrayLayer]] is used instead of the OpenLayer cmd.
* When AppletResourceUserId!=0, [[AM_services#CreateManagedDisplayLayer]] is used and the output from that is used for LayerId with the OpenLayer cmd.

This OpenLayer command returns error 0x272 when the AppletResourceUserId is invalid.

== CloseLayer ==
Takes an input u64: LayerId which was used with [[#OpenLayer]].

== CreateStrayLayer ==
Takes a type-0x6 buffer for the output [[#NativeWindow]], an u32(LayerFlags bitmask), and an u64 DisplayId. Returns two output u64s: LayerId and NativeWindow_Size.

== DestroyStrayLayer ==
Takes an input u64: LayerId from [[#CreateStrayLayer]].

== SetLayerScalingMode ==
Takes an input u64("ScalingMode") and u64 ("LayerId").

== GetIndirectLayerImageMap ==
Takes a PID-descriptor, an type-0x46 buffer, and four u64s: width(s32), height(s32), <output from [[AM_services|AM]] GetIndirectLayerConsumerHandle>, and [[AM_services|AppletResourceUserId]]. Returns two output u64s.

== GetIndirectLayerImageCropMap ==
Takes a PID-descriptor, an type-0x46 buffer, four floats, four u64s(last u64 is [[AM_services|AppletResourceUserId]]). Returns two output u64s. The floats are stored immediately after each other(32bits).

== GetIndirectLayerImageRequiredMemoryInfo ==
Takes two input u64s: with and height. Returns two output u64s. First u64 is the buffer size to use with the ImageMap cmds.

== GetDisplayVsyncEvent ==
Takes an input u64 DisplayId and returns a handle.

== GetDisplayVsyncEventForDebug ==
Takes an input u64 DisplayId and returns a handle.

== ISystemDisplayService ==
This is "nn::visrv::sf::ISystemDisplayService".

This normally contains an u32 with value 0?

= Resolution handling =
There doesn't seem to be a way to get the actual TV resolution while using the "Default" Display. Official apps just hard-code what resolution to use depending on the current [[AM_services|OperationMode]].

Available sessions for each service:
* "vi:u": Only GetRelayService.
* "vi:s": Everything except GetManagerDisplayService.
* "vi:m": All.

When attempting to use a get-session cmd with a service it's not available with, error 0xA72 is returned.

These commands using PIDs have AppletResourceUserId as the last input u64, hence AppletResourceUserId must [[IPC_Marshalling|match]] the user-process PID(no special handling for value 0).

== GetRelayService ==
Returns an [[Nvnflinger_services#dispdrv|IHOSBinderDriver]] interface which abstracts "nn::visrv::service::RelayServiceImpl".

== GetIndirectDisplayTransactionService ==
Returns an [[Nvnflinger_services#dispdrv|IHOSBinderDriver]] interface which abstracts "nn::visrv::service::IndirectDisplayTransactionServiceImpl".

== GetSystemDisplayService ==
Returns an [[#ISystemDisplayService]].

== GetManagerDisplayService ==
Returns an [[#IManagerDisplayService]].

== ListDisplays ==
Takes a type-0x6 output buffer containing the array of [[#DisplayInfo]] output entries. Returns an output u64: total number of output entries.

Normally(?) this only returns the "Default" display.

== OpenDisplay ==
Takes a [[#DisplayName]] as input. Returns an output u64, the DisplayId.

To open the default display, input string "Default" can be used.

== OpenDefaultDisplay ==
Returns an output u64.

Probably not (?) used by newer official user-processes, since those use OpenDisplay with the default string instead.

== CloseDisplay ==
Takes an input u64, DisplayId.

== SetDisplayEnabled ==
Takes an input u32 boolean, and an u64 DisplayId.

== GetDisplayResolution ==
Takes an input u64 DisplayId and returns two output u64s: width and height.

== OpenLayer ==
Takes a PID-descriptor, a type-0x6 buffer for the output [[#NativeWindow]], a [[#DisplayName]](which was previously used with [[#OpenDisplay]]), an u64 LayerId, and an u64 [[AM_services|AppletResourceUserId]]. Returns an output u64 NativeWindow_Size.

Official user-processes use a LayerId stored in a global state field("...ExternalLayerId") if non-zero, otherwise:
* When AppletResourceUserId==0, [[#CreateStrayLayer]] is used instead of the OpenLayer cmd.
* When AppletResourceUserId!=0, [[AM_services#CreateManagedDisplayLayer]] is used and the output from that is used for LayerId with the OpenLayer cmd.

This OpenLayer command returns error 0x272 when the AppletResourceUserId is invalid.

== CloseLayer ==
Takes an input u64: LayerId which was used with [[#OpenLayer]].

== CreateStrayLayer ==
Takes a type-0x6 buffer for the output [[#NativeWindow]], an u32(LayerFlags bitmask), and an u64 DisplayId. Returns two output u64s: LayerId and NativeWindow_Size.

== DestroyStrayLayer ==
Takes an input u64: LayerId from [[#CreateStrayLayer]].

== SetLayerScalingMode ==
Takes an input u64("ScalingMode") and u64 ("LayerId").

== GetIndirectLayerImageMap ==
Takes a PID-descriptor, an type-0x46 buffer, and four u64s: width(s32), height(s32), <output from [[AM_services|AM]] GetIndirectLayerConsumerHandle>, and [[AM_services|AppletResourceUserId]]. Returns two output u64s.

== GetIndirectLayerImageCropMap ==
Takes a PID-descriptor, an type-0x46 buffer, four floats, four u64s(last u64 is [[AM_services|AppletResourceUserId]]). Returns two output u64s. The floats are stored immediately after each other(32bits).

== GetIndirectLayerImageRequiredMemoryInfo ==
Takes two input u64s: with and height. Returns two output u64s. First u64 is the buffer size to use with the ImageMap cmds.

== GetDisplayVsyncEvent ==
Takes an input u64 DisplayId and returns a handle.

== GetDisplayVsyncEventForDebug ==
Takes an input u64 DisplayId and returns a handle.

== ISystemDisplayService ==
This is "nn::visrv::sf::ISystemDisplayService".

This is a 0x60-byte structure.

The width/height for the "Default" Display is the resolution for 1080p even when in handheld-mode.

= DisplayName =
This is a 0x40-byte block: a NUL-terminated string.

Can be "Default", "External", "Edid", "Internal" or "Null".

= NativeWindow =
Max size of this buffer is 0x100-bytes(outbuf size used by official user-processes). Parsed("...DeserializeNativeWindow()") by a function called by the code described under [[#OpenLayer]], which executes code with Android symbols.

This is a [[#Parcel]].

== ParcelData ==
This normally contains the following:

{| class="wikitable" border="1"
|-
! Offset || Size || Description
|-
| 0x0 || 0x4 || 0x2
|-
| 0x4 || 0x4 || Probably the user-process PID?

|-
| 0x18 || 0x8 || NUL-terminated "dispdrv" string.
|-
| 0x20 || 0x8 || All-zero normally?
|}

The above ID is used for the ID param for the binder commands with [[#GetRelayService|IHOSBinderDriver]].

== ParcelObjects ==
This normally contains an u32 with value 0?

= Resolution handling =
There doesn't seem to be a way to get the actual TV resolution while using the "Default" Display. Official apps just hard-code what resolution to use depending on the current [[AM_services|OperationMode]].

Error codes

2019-01-02T12:16:16Z

Lioncache: Add VI error code that indicates unsupported/unimplemented operations (this is used as a return value in some stubbed functions within vtables)

= Structure =
These have been redesigned from the 3DS so that they fit within a Aarch64 MOV instruction immediate most of the time (without requiring the additional MOVK).

{| class=wikitable
! Bits || Field
|-
| 8-0 || Module
|-
| 21-9 || Description

When a fatal-error is received the error code is outputted using the following formatter:
%04d-%04d

.. where the first code is <code>2000 + Module</code>, and the other being <code>Description</code>. Bits >=22 from the error-code are unused when displaying fatal-errors, since the Description ends with bit21.

When a fatal-error is received the error code is outputted using the following formatter:
%04d-%04d

.. where the first code is <code>2000 + Module</code>, and the other being <code>Description</code>. Bits >=22 from the error-code are unused when displaying fatal-errors, since the Description ends with bit21.

When a fatal-error is received the error code is outputted using the following formatter:
%04d-%04d

.. where the first code is <code>2000 + Module</code>, and the other being <code>Description</code>. Bits >=22 from the error-code are unused when displaying fatal-errors, since the Description ends with bit21.

Error codes

2018-12-30T19:58:12Z

Lioncache: Add time error codes for out of range values and for cases when things cannot be found. These are both used in the implementation of ToPosixTime when looking up timezone entries based off a given rule.

= Structure =
These have been redesigned from the 3DS so that they fit within a Aarch64 MOV instruction immediate most of the time (without requiring the additional MOVK).

| 21-9 || Description

When a fatal-error is received the error code is outputted using the following formatter:
%04d-%04d

.. where the first code is <code>2000 + Module</code>, and the other being <code>Description</code>. Bits >=22 from the error-code are unused when displaying fatal-errors, since the Description ends with bit21.

Error codes

Lioncache: Add time error code for memory allocation failures. This is (as would be expected) used mostly near the service boundaries where allocations are necessary for different handle types

= Structure =
These have been redesigned from the 3DS so that they fit within a Aarch64 MOV instruction immediate most of the time (without requiring the additional MOVK).

{| class=wikitable
! Bits || Field

| 8-0 || Module
|-
| 21-9 || Description
|}

When a fatal-error is received the error code is outputted using the following formatter:
%04d-%04d

.. where the first code is <code>2000 + Module</code>, and the other being <code>Description</code>. Bits >=22 from the error-code are unused when displaying fatal-errors, since the Description ends with bit21.

Error codes

2018-12-29T18:41:18Z

Lioncache: Add time error code for unimplemented functionality. This seems to be used in inheritance trees to indicate unimplemented behavior in different class implementations for a few functions

= Structure =
These have been redesigned from the 3DS so that they fit within a Aarch64 MOV instruction immediate most of the time (without requiring the additional MOVK).

{| class=wikitable
! Bits || Field
|-
| 8-0 || Module
|-
| 21-9 || Description
|}

When a fatal-error is received the error code is outputted using the following formatter:
%04d-%04d

.. where the first code is <code>2000 + Module</code>, and the other being <code>Description</code>. Bits >=22 from the error-code are unused when displaying fatal-errors, since the Description ends with bit21.

When a fatal-error is received the error code is outputted using the following formatter:
%04d-%04d

.. where the first code is <code>2000 + Module</code>, and the other being <code>Description</code>. Bits >=22 from the error-code are unused when displaying fatal-errors, since the Description ends with bit21.

When a fatal-error is received the error code is outputted using the following formatter:
%04d-%04d

.. where the first code is <code>2000 + Module</code>, and the other being <code>Description</code>. Bits >=22 from the error-code are unused when displaying fatal-errors, since the Description ends with bit21.

Lioncache: Add PDM error codes related to user IDs

= Structure =
These have been redesigned from the 3DS so that they fit within a Aarch64 MOV instruction immediate most of the time (without requiring the additional MOVK).

{| class=wikitable
! Bits || Field
|-
| 8-0 || Module
|-
| 21-9 || Description
|}

When a fatal-error is received the error code is outputted using the following formatter:
%04d-%04d

.. where the first code is <code>2000 + Module</code>, and the other being <code>Description</code>. Bits >=22 from the error-code are unused when displaying fatal-errors, since the Description ends with bit21.

These have been redesigned from the 3DS so that they fit within a Aarch64 MOV instruction immediate most of the time (without requiring the additional MOVK).

{| class=wikitable
! Bits || Field

| 8-0 || Module
|-
| 21-9 || Description
|}

When a fatal-error is received the error code is outputted using the following formatter:
%04d-%04d

.. where the first code is <code>2000 + Module</code>, and the other being <code>Description</code>. Bits >=22 from the error-code are unused when displaying fatal-errors, since the Description ends with bit21.

When a fatal-error is received the error code is outputted using the following formatter:
%04d-%04d

.. where the first code is <code>2000 + Module</code>, and the other being <code>Description</code>. Bits >=22 from the error-code are unused when displaying fatal-errors, since the Description ends with bit21.

When a fatal-error is received the error code is outputted using the following formatter:
%04d-%04d

.. where the first code is <code>2000 + Module</code>, and the other being <code>Description</code>. Bits >=22 from the error-code are unused when displaying fatal-errors, since the Description ends with bit21.

These have been redesigned from the 3DS so that they fit within a Aarch64 MOV instruction immediate most of the time (without requiring the additional MOVK).

| 21-9 || Description

When a fatal-error is received the error code is outputted using the following formatter:
%04d-%04d

.. where the first code is <code>2000 + Module</code>, and the other being <code>Description</code>. Bits >=22 from the error-code are unused when displaying fatal-errors, since the Description ends with bit21.

Lioncache: Add settings module error codes for null settings names and keys

= Structure =
These have been redesigned from the 3DS so that they fit within a Aarch64 MOV instruction immediate most of the time (without requiring the additional MOVK).

{| class=wikitable

| 8-0 || Module
|-
| 21-9 || Description
|}

When a fatal-error is received the error code is outputted using the following formatter:
%04d-%04d

.. where the first code is <code>2000 + Module</code>, and the other being <code>Description</code>. Bits >=22 from the error-code are unused when displaying fatal-errors, since the Description ends with bit21.

Error codes

2018-12-23T07:07:11Z

Lioncache: Add mii error code that indicates if certain behaviors are dev/debug-only functionality. When present, this is usually always preceded by a call into the set:sys module checking if the bool "is_db_test_mode_enabled" settings key has a true value set.

= Structure =
These have been redesigned from the 3DS so that they fit within a Aarch64 MOV instruction immediate most of the time (without requiring the additional MOVK).

{| class=wikitable
! Bits || Field
|-
| 8-0 || Module
|-
| 21-9 || Description
|}

When a fatal-error is received the error code is outputted using the following formatter:
%04d-%04d

.. where the first code is <code>2000 + Module</code>, and the other being <code>Description</code>. Bits >=22 from the error-code are unused when displaying fatal-errors, since the Description ends with bit21.

Lioncache: Add FS error code for allocator alignment violations

= Structure =
These have been redesigned from the 3DS so that they fit within a Aarch64 MOV instruction immediate most of the time (without requiring the additional MOVK).

{| class=wikitable
! Bits || Field
|-
| 8-0 || Module
|-
| 21-9 || Description
|}

When a fatal-error is received the error code is outputted using the following formatter:
%04d-%04d

.. where the first code is <code>2000 + Module</code>, and the other being <code>Description</code>. Bits >=22 from the error-code are unused when displaying fatal-errors, since the Description ends with bit21.

Lioncache: Add mii error code for entries that can't be found.

= Structure =
These have been redesigned from the 3DS so that they fit within a Aarch64 MOV instruction immediate most of the time (without requiring the additional MOVK).

When a fatal-error is received the error code is outputted using the following formatter:
%04d-%04d

.. where the first code is <code>2000 + Module</code>, and the other being <code>Description</code>. Bits >=22 from the error-code are unused when displaying fatal-errors, since the Description ends with bit21.

When a fatal-error is received the error code is outputted using the following formatter:
%04d-%04d

.. where the first code is <code>2000 + Module</code>, and the other being <code>Description</code>. Bits >=22 from the error-code are unused when displaying fatal-errors, since the Description ends with bit21.

== RegisterProgram ==
Takes a storageID, a pid, a titleID, a 0x1C type-A buffer for the [[NPDM#FS_Access_Header| FS Access Header]], and a 0x2C type-A buffer for the [[NPDM#FS_Access_Control| FS Access Control]]

Final FS permissions are stored as (ACI0_perms & ACID_perms). Will panic(svcBreak) when buffer sizes from ipc-rawdata are invalid.

== UnregisterProgram ==
Takes a pid. Removes registered FS permissions for that PID.

== SetEnabledProgramVerification ==
Seems to sets a global flag to inputval & 1.

When the flag is zero, it will set ret=0 instead of ret={error} when verifying the fixed-key [[NPDM]] ACID signature fails. This also skips verifying the [[NCA_Format|NCA Header]] signature using the ACID key. Note that if verifying the fixed-key ACID signature is successful, and verifying the ACID-key NCA header signature fails, it will throw an error and abort.

== Permissions ==
Every time permissions are checked, the process registration [[#fsp-pr]] is loaded using the session processID. The permission data is populated with data from the [[NPDM]].

If the processID is <= 6 (which happens only for built-in sysmodules), it will use a hardcoded registration data. The default mask in this case is 0x8000000000000000.

Note that the functions check whether or not at least one bit is set in the mask. This means that, you don't need to set 0xFFFFFFFFFFFFFFFF to get all permissions: it suffices to set 0x8000000000000000.

If the code were to request an invalid input type, panic. But this never happens.

== OpenFileSystem ==
Takes a type-0x19 input buffer (ContentPath) and a [[#FileSystemType]] as parameters. Returns an [[#IFileSystem]].

[2.0.0+] This function was removed.

== SetCurrentProcess ==
Takes a pid-descriptor.

== OpenFileSystemWithPatch ==
Takes an input [[#FileSystemType]] and an u64 title-id. Returns an [[#IFileSystem]].

Web-applet loads the [[#FileSystemType]] (which must be '''ContentManual''') from u32_table[inparam].

Note: web-applet strings refer to both this cmd and [[#OpenFileSystemWithId]] as "MountContent", but official nn_sf_sync symbols use "OpenXX" names.

== OpenFileSystemWithId ==
Takes a type-0x19 input buffer, an [[#FileSystemType]] and an u64 title-id. Returns an [[#IFileSystem]].

The [[#IFileSystem]] must be '''ContentMeta''' if the NCA type is 0 (control).

The input buffer is the output string path from [[NS_Services#GetApplicationContentPath|GetApplicationContentPath]].

May return errors when attempting to access NCA-paths for an update-title with a gamecard, when the gamecard isn't inserted. May return error 0x7D402 in some cases with update-titles. Non-val2 in32 values with NCA-type1 are unusable, even for normal titles.

The official "MountApplicationPackage" func uses this with in64=0 and [[#FileSystemType]] '''ApplicationPackage'''.

After the [[#FileSystemType]] specific permissions are checked, it then gets the func retval for permissions-type 0x25 and func0.

When [[#FileSystemType]] is '''ContentMeta''', it uses in64=0xffffffffffffffff internally, otherwise it checks if in64 is set to 0xffffffffffffffff then throws an error if so. When the in64 used internally is not 0xffffffffffffffff, it's compared with the NCA titleID, then an error is thrown on mismatch.

== OpenBisFileSystem ==
Takes a type-0x19 input buffer string and a u32 [[Flash_Filesystem|Bis partitionID]]. Official user-process code sets instr[0] = 0 normally. Returns an [[#IFileSystem]].

Only partitionIDs for FAT partitions are usable with this, otherwise error 0x2EE202 is returned. Seems to be about the same as [[#OpenBisStorage]] except this mounts the partition filesystem instead of allowing direct access to the partition sectors.

== OpenBisStorage ==
Takes a u32 partition ID, returns 0x2EE202 for partitions which do not exist, 0x320002 for partitions which cannot be opened and a valid [[#IStorage]] handle otherwise.

== InvalidateBisCache ==
Seems to invalidate the Bis cache for MBR/GPT after overwriting that data via the OpenBisStorage IStorage. Used by [[SystemInitializer]].

== DeleteSaveDataFileSystem ==
Takes an input u64.

== CreateSaveDataFileSystem ==
Takes a 0x40-byte Save-struct entry, a 0x40-byte SaveCreate-struct entry, and a 0x10-byte input struct.

Only the first 0x5-bytes in the 0x10-byte struct are initialized: all-zero when automatically creating savedata during savecommon mount by official user-processes. In the dedicated save-creation code in official user-processes: +0 u32 = 0x40060, +4 u8 = 1.

Creates regular savedata.

== CreateSaveDataFileSystemBySystemSaveDataId ==
Takes a 0x40-byte Save-struct entry and a 0x40-byte SaveCreate-struct entry.

Creates savedata in the SYSTEM [[Flash_Filesystem|NAND]] partition.

== OpenGameCardStorage ==
Takes two input u32s (gamecard handle, partition ID), and returns an [[#IStorage]] for the [[Gamecard_Format|partition]].

== OpenGameCardFileSystem ==
Takes two input u32s, with the second u32 located at +4 in rawdata after the first u32. Returns an [[#IFileSystem]].

Mounts a [[Gamecard_Partition|gamecard partition]].

== OpenSaveDataFileSystem ==
Takes an input u8 [[#SaveDataSpaceId]] and a 0x40-byte Save-struct entry. Official user-process code is only known to use value 1 for the u8.

Returns an [[#IFileSystem]].

Permissions aren't checked until the specified save is successfully found.

Only one process (specifically only one [[#IFileSystem]] session) can mount a given savedata at any given time (this includes SystemSaveData).

== OpenSaveDataFileSystemBySystemSaveDataId ==
Takes an input u8 [[#SaveDataSpaceId]] and a 0x40-byte Save-struct entry. Web-applet only uses value0 for the input u8.

Returns an [[#IFileSystem]].

Mounts savedata in the SYSTEM [[Flash_Filesystem|NAND]] partition.

== ReadSaveDataFileSystemExtraDataBySaveDataSpaceId ==
Takes an input u8 [[#SaveDataSpaceId]], an input u64 saveID, and a type-0x6 output buffer containing the [[#SaveDataFileSystemExtraData]].

== ReadSaveDataFileSystemExtraData ==
Takes an input u64 saveID and a type-0x6 output buffer containing the [[#SaveDataFileSystemExtraData]].

== OpenSaveDataInfoReader ==
No input, returns an output [[#ISaveDataInfoReader]].

== OpenSaveDataInfoReaderBySaveDataSpaceId ==
Takes an input u8 [[#SaveDataSpaceId]], returns an output [[#ISaveDataInfoReader]].

== OpenContentStorageFileSystem ==
Takes a [[#ContentStorageId]]. Invalid values return 0x2EE202.

Returns an [[#IFileSystem]] with NCA files. The read data from these files is identical to the data read by [[NCM_services#ReadContentIdFile]].

== OpenDataStorageByDataId ==
Takes a [[#StorageId]] and a TitleID.

Returns a [[IPC_Marshalling#Domain_message|domain object ID]] implementing the [[#IStorage]] interface for data archives.

== OpenDeviceOperator ==
This command returns a session to a port implementing the [[#IDeviceOperator]] interface.

== OpenSdCardDetectionEventNotifier ==
This command returns a session to a port implementing the [[#IEventNotifier]] interface.

== OpenGameCardDetectionEventNotifier ==
This command returns a session to a port implementing the [[#IEventNotifier]] interface.

== VerifySaveDataFileSystem ==
Takes an unknown input u64 and a type-0x6 output buffer.

The input u64 high-byte must be non-zero, otherwise an [[Error_codes|error]] is returned(0xE02).

== GetSaveDataCommitId ==
Takes an input u8 and u64, returns an output u64.

== SetSdCardEncryptionSeed ==
Takes in the 0x10 byte SD card encryption seed, and loads it into FS-module state.

[[NS_Services|NS]]-module reads the 0x10 bytes from SdCard:/Nintendo/Contents/private, and compares them to the first 0x10 bytes of the ns_appman:/private (in [[Flash_Filesystem#System_Savegames|system savedata]] 0x8000000000000043). If they match, NS calls this command using bytes 0x10-0x20 from ns_appman:/private. The rest of this file (0x1F0 bytes total) is (usually/always?) all-zero.

== SetGlobalAccessLogMode ==
Takes an input u32.

== GetGlobalAccessLogMode ==
Returns an output u32.

GlobalAccessLogMode is normally 0.

== OutputAccessLogToSdCard ==
Takes a type-0x5 input buffer.

The input buffer is the string to output to the log. User-processes normally include a newline at the end.

User-processes only use this when the value previously loaded from [[#GetGlobalAccessLogMode]] has bit1 set.

When bit1 in GlobalAccessLogMode is clear, FS-module will just return 0 for OutputAccessLogToSdCard. However even with that set the log doesn't show up SD, unknown why.

The input buffer is written to the "$FsAccessLog:/FsAccessLog.txt" file, where "$FsAccessLog" is the SD-card mount-name. It's written to the current end of the file(appended).

= IFileSystem =
This is "nn::fssrv::sf::IFileSystem".

There are two main implementations of this interface:

* '''RomFS''': Filesystem implementation statically linked in the binary. Uses an [[#IStorage]] interface as underlying raw device.
* '''IPC proxy''': Used for all non-RomFS filesystems. In this case, actual filesystem implementation is in the FS process.

== GetEntryType ==
Takes a type-0x9 input buffer for the path and returns [[#DirectoryEntryType]] as an output u32.

== OpenFile ==
Takes a type-0x19 input buffer for the path, and an u32 '''mode'''. '''mode''' controls how the file is opened, based on which bits are set:

* When bit 0 is set, the file is Readable: you can use the Read operation.
* When bit 1 is set, the file is Writable: you can use the Write operation.
* When bit 2 is set, the file is Appendable: unless this bit is set, you will not be able to write beyond the end of a file (such writes will result in an error 0x307202)

== OpenDirectory ==
Takes a type-0x9 input buffer for the path and an u64 '''filter_flags'''. '''filter_flags''' controls what type of entries are read by the [[#IDirectory]]: bitmask 0x1 = directories, bitmask 0x2 = files.

== Commit ==
Like [https://3dbrew.org/wiki/FS:ControlArchive 3DS], this has to be used after writing to savedata for the changes to take affect.

== GetFreeSpaceSize ==
Takes a type-0x9 input buffer for the path and returns an output byte-size u64 for the total free space with this FS.

== GetTotalSpaceSize ==

== GetGameCardUpdatePartitionInfo ==
Returns a titleID and the title-version for it.

* Output u32 with ARMS-gamecard: title-version v131162. This is the title-version for [[2.1.0]], which is the sysupdate included with this gamecard. Launch-day gamecards return title-version v450.
* Output u64 with ARMS-gamecard: titleID 0100000000000816.

[[NS_Services|NS]] appears to only use this with [[Content_Manager_services#GetTitleIdInfo]] and [[Content_Manager_services#GetUpdateTitleList]] with storageid=nandsys, for checking whether a sysupdate is required.

== RegisterProgram ==
Takes a storageID, a pid, a titleID, a 0x1C type-A buffer for the [[NPDM#FS_Access_Header| FS Access Header]], and a 0x2C type-A buffer for the [[NPDM#FS_Access_Control| FS Access Control]]

Final FS permissions are stored as (ACI0_perms & ACID_perms). Will panic(svcBreak) when buffer sizes from ipc-rawdata are invalid.

== UnregisterProgram ==
Takes a pid. Removes registered FS permissions for that PID.

== SetEnabledProgramVerification ==
Seems to sets a global flag to inputval & 1.

When the flag is zero, it will set ret=0 instead of ret={error} when verifying the fixed-key [[NPDM]] ACID signature fails. This also skips verifying the [[NCA_Format|NCA Header]] signature using the ACID key. Note that if verifying the fixed-key ACID signature is successful, and verifying the ACID-key NCA header signature fails, it will throw an error and abort.

== Permissions ==
Every time permissions are checked, the process registration [[#fsp-pr]] is loaded using the session processID. The permission data is populated with data from the [[NPDM]].

If the processID is <= 6 (which happens only for built-in sysmodules), it will use a hardcoded registration data. The default mask in this case is 0x8000000000000000.

Note that the functions check whether or not at least one bit is set in the mask. This means that, you don't need to set 0xFFFFFFFFFFFFFFFF to get all permissions: it suffices to set 0x8000000000000000.

If the code were to request an invalid input type, panic. But this never happens.

== OpenFileSystem ==
Takes a type-0x19 input buffer (ContentPath) and a [[#FileSystemType]] as parameters. Returns an [[#IFileSystem]].

[2.0.0+] This function was removed.

== SetCurrentProcess ==
Takes a pid-descriptor.

== OpenFileSystemWithPatch ==
Takes an input [[#FileSystemType]] and an u64 title-id. Returns an [[#IFileSystem]].

Web-applet loads the [[#FileSystemType]] (which must be '''ContentManual''') from u32_table[inparam].

Note: web-applet strings refer to both this cmd and [[#OpenFileSystemWithId]] as "MountContent", but official nn_sf_sync symbols use "OpenXX" names.

== OpenFileSystemWithId ==
Takes a type-0x19 input buffer, an [[#FileSystemType]] and an u64 title-id. Returns an [[#IFileSystem]].

The [[#IFileSystem]] must be '''ContentMeta''' if the NCA type is 0 (control).

The input buffer is the output string path from [[NS_Services#GetApplicationContentPath|GetApplicationContentPath]].

May return errors when attempting to access NCA-paths for an update-title with a gamecard, when the gamecard isn't inserted. May return error 0x7D402 in some cases with update-titles. Non-val2 in32 values with NCA-type1 are unusable, even for normal titles.

The official "MountApplicationPackage" func uses this with in64=0 and [[#FileSystemType]] '''ApplicationPackage'''.

After the [[#FileSystemType]] specific permissions are checked, it then gets the func retval for permissions-type 0x25 and func0.

When [[#FileSystemType]] is '''ContentMeta''', it uses in64=0xffffffffffffffff internally, otherwise it checks if in64 is set to 0xffffffffffffffff then throws an error if so. When the in64 used internally is not 0xffffffffffffffff, it's compared with the NCA titleID, then an error is thrown on mismatch.

== OpenBisFileSystem ==
Takes a type-0x19 input buffer string and a u32 [[Flash_Filesystem|Bis partitionID]]. Official user-process code sets instr[0] = 0 normally. Returns an [[#IFileSystem]].

Only partitionIDs for FAT partitions are usable with this, otherwise error 0x2EE202 is returned. Seems to be about the same as [[#OpenBisStorage]] except this mounts the partition filesystem instead of allowing direct access to the partition sectors.

== OpenBisStorage ==
Takes a u32 partition ID, returns 0x2EE202 for partitions which do not exist, 0x320002 for partitions which cannot be opened and a valid [[#IStorage]] handle otherwise.

== InvalidateBisCache ==
Seems to invalidate the Bis cache for MBR/GPT after overwriting that data via the OpenBisStorage IStorage. Used by [[SystemInitializer]].

== DeleteSaveDataFileSystem ==
Takes an input u64.

== CreateSaveDataFileSystem ==
Takes a 0x40-byte Save-struct entry, a 0x40-byte SaveCreate-struct entry, and a 0x10-byte input struct.

Only the first 0x5-bytes in the 0x10-byte struct are initialized: all-zero when automatically creating savedata during savecommon mount by official user-processes. In the dedicated save-creation code in official user-processes: +0 u32 = 0x40060, +4 u8 = 1.

Creates regular savedata.

== CreateSaveDataFileSystemBySystemSaveDataId ==
Takes a 0x40-byte Save-struct entry and a 0x40-byte SaveCreate-struct entry.

Creates savedata in the SYSTEM [[Flash_Filesystem|NAND]] partition.

== OpenGameCardStorage ==
Takes two input u32s (gamecard handle, partition ID), and returns an [[#IStorage]] for the [[Gamecard_Format|partition]].

== OpenGameCardFileSystem ==
Takes two input u32s, with the second u32 located at +4 in rawdata after the first u32. Returns an [[#IFileSystem]].

Mounts a [[Gamecard_Partition|gamecard partition]].

== OpenSaveDataFileSystem ==
Takes an input u8 [[#SaveDataSpaceId]] and a 0x40-byte Save-struct entry. Official user-process code is only known to use value 1 for the u8.

Returns an [[#IFileSystem]].

Permissions aren't checked until the specified save is successfully found.

Only one process (specifically only one [[#IFileSystem]] session) can mount a given savedata at any given time (this includes SystemSaveData).

== OpenSaveDataFileSystemBySystemSaveDataId ==
Takes an input u8 [[#SaveDataSpaceId]] and a 0x40-byte Save-struct entry. Web-applet only uses value0 for the input u8.

Returns an [[#IFileSystem]].

Mounts savedata in the SYSTEM [[Flash_Filesystem|NAND]] partition.

== ReadSaveDataFileSystemExtraDataBySaveDataSpaceId ==
Takes an input u8 [[#SaveDataSpaceId]], an input u64 saveID, and a type-0x6 output buffer containing the [[#SaveDataFileSystemExtraData]].

== ReadSaveDataFileSystemExtraData ==
Takes an input u64 saveID and a type-0x6 output buffer containing the [[#SaveDataFileSystemExtraData]].

== OpenSaveDataInfoReader ==
No input, returns an output [[#ISaveDataInfoReader]].

== OpenSaveDataInfoReaderBySaveDataSpaceId ==
Takes an input u8 [[#SaveDataSpaceId]], returns an output [[#ISaveDataInfoReader]].

== OpenContentStorageFileSystem ==
Takes a [[#ContentStorageId]]. Invalid values return 0x2EE202.

Returns an [[#IFileSystem]] with NCA files. The read data from these files is identical to the data read by [[NCM_services#ReadContentIdFile]].

== OpenDataStorageByDataId ==
Takes a [[#StorageId]] and a TitleID.

Returns a [[IPC_Marshalling#Domain_message|domain object ID]] implementing the [[#IStorage]] interface for data archives.

== OpenDeviceOperator ==
This command returns a session to a port implementing the [[#IDeviceOperator]] interface.

== OpenSdCardDetectionEventNotifier ==
This command returns a session to a port implementing the [[#IEventNotifier]] interface.

== OpenGameCardDetectionEventNotifier ==
This command returns a session to a port implementing the [[#IEventNotifier]] interface.

== VerifySaveDataFileSystem ==
Takes an unknown input u64 and a type-0x6 output buffer.

The input u64 high-byte must be non-zero, otherwise an [[Error_codes|error]] is returned(0xE02).

== GetSaveDataCommitId ==
Takes an input u8 and u64, returns an output u64.

== SetSdCardEncryptionSeed ==
Takes in the 0x10 byte SD card encryption seed, and loads it into FS-module state.

[[NS_Services|NS]]-module reads the 0x10 bytes from SdCard:/Nintendo/Contents/private, and compares them to the first 0x10 bytes of the ns_appman:/private (in [[Flash_Filesystem#System_Savegames|system savedata]] 0x8000000000000043). If they match, NS calls this command using bytes 0x10-0x20 from ns_appman:/private. The rest of this file (0x1F0 bytes total) is (usually/always?) all-zero.

== SetGlobalAccessLogMode ==
Takes an input u32.

== GetGlobalAccessLogMode ==
Returns an output u32.

GlobalAccessLogMode is normally 0.

== OutputAccessLogToSdCard ==
Takes a type-0x5 input buffer.

The input buffer is the string to output to the log. User-processes normally include a newline at the end.

User-processes only use this when the value previously loaded from [[#GetGlobalAccessLogMode]] has bit1 set.

When bit1 in GlobalAccessLogMode is clear, FS-module will just return 0 for OutputAccessLogToSdCard. However even with that set the log doesn't show up SD, unknown why.

The input buffer is written to the "$FsAccessLog:/FsAccessLog.txt" file, where "$FsAccessLog" is the SD-card mount-name. It's written to the current end of the file(appended).

= IStorage =
This is "nn::fssrv::sf::IStorage".

This is the interface for a raw device, usually a block device.

= IFileSystem =
This is "nn::fssrv::sf::IFileSystem".

There are two main implementations of this interface:

* '''RomFS''': Filesystem implementation statically linked in the binary. Uses an [[#IStorage]] interface as underlying raw device.
* '''IPC proxy''': Used for all non-RomFS filesystems. In this case, actual filesystem implementation is in the FS process.

== GetEntryType ==
Takes a type-0x9 input buffer for the path and returns [[#DirectoryEntryType]] as an output u32.

== OpenFile ==
Takes a type-0x19 input buffer for the path, and an u32 '''mode'''. '''mode''' controls how the file is opened, based on which bits are set:

* When bit 0 is set, the file is Readable: you can use the Read operation.
* When bit 1 is set, the file is Writable: you can use the Write operation.
* When bit 2 is set, the file is Appendable: unless this bit is set, you will not be able to write beyond the end of a file (such writes will result in an error 0x307202)

== OpenDirectory ==
Takes a type-0x9 input buffer for the path and an u64 '''filter_flags'''. '''filter_flags''' controls what type of entries are read by the [[#IDirectory]]: bitmask 0x1 = directories, bitmask 0x2 = files.

== Commit ==
Like [https://3dbrew.org/wiki/FS:ControlArchive 3DS], this has to be used after writing to savedata for the changes to take affect.

== GetFreeSpaceSize ==
Takes a type-0x9 input buffer for the path and returns an output byte-size u64 for the total free space with this FS.

== GetTotalSpaceSize ==
Takes a type-0x9 input buffer for the path and returns an output byte-size u64 for the total space available with this FS(free+used).

== CleanDirectoryRecursively ==
Takes a type-0x9 input buffer for the path and clears the contents of the directory specified in the path.

== GetFileTimeStampRaw ==
Takes a type-0x19 input buffer for the path and returns a 0x20-byte struct. This contains 3 u64s and an u8.

== GetGameCardUpdatePartitionInfo ==
Returns a titleID and the title-version for it.

* Output u32 with ARMS-gamecard: title-version v131162. This is the title-version for [[2.1.0]], which is the sysupdate included with this gamecard. Launch-day gamecards return title-version v450.
* Output u64 with ARMS-gamecard: titleID 0100000000000816.

'''Description:''' Maps a memory range into a different range.

Mainly used for adding guard pages around stack.

Source range gets reprotected to --- (it can no longer be accessed), and bit0 is set in the source [[#MemoryAttribute]].

[1.0.0] This could be used to map into either the Alias Region or the Stack region.

[2.0.0+] This can only be used to map into the Stack region.

Code can get the range of the Alias region from [[#svcGetInfo]] id0=2,3, and on 2.0.0+ the range of the Stack region via [[#svcGetInfo]] id0=14, 15 (on 1.0.0, the Stack region had hardcoded limits).

When mapped into the Alias region, the mapped memory will have state 0x482907.

When mapped into the Stack region, the mapped memory will have state 0x5C3C0B.

Works with num_handles <= 0x40.

When zero handles are passed, this will wait forever until either timeout or cancellation occurs.

Does not accept 0xFFFF8001 or 0xFFFF8000 as handles.

=== Object types ===

'''KDebug:''' signals when there is a new [[#DebugEventInfo|DebugEvent]] (retrievable via [[#svcGetDebugEvent]]).

'''KClientPort:''' signals when the number of sessions is less than the maximum allowed.

'''KProcess:''' signals when the process undergoes a state change (retrievable via [[#svcGetProcessInfo]]).

'''KReadableEvent:''' signals when the event's corresponding KWritableEvent has been signaled via svcSignalEvent.

'''KServerPort:''' signals when there is an incoming connection waiting to be [[#svcAcceptSession|accepted]].

'''KServerSession:''' signals when there is an incoming message waiting to be [[#svcReplyAndReceive|received]] or the pipe is closed.

'''KThread:''' signals when the thread has exited.

=== Result codes ===

'''0x0:''' Success. One of the objects was signaled before the timeout expired, or one of the objects is a Session with a closed remote. Handle index is updated to indicate which object signaled.

'''0x7601:''' Thread termination requested. Handle index is not updated.

'''0xe401:''' Invalid handle. Returned when one of the handles passed is invalid. Handle index is not updated.

'''0xe601:''' Invalid address. Returned when the handles pointer is not a readable address. Handle index is not updated.

'''0xea01:''' Timeout. Returned when no objects have been signaled within the timeout. Handle index is not updated.

'''0xec01:''' Interrupted. Returned when another thread uses [[#svcCancelSynchronization]] to cancel this thread. Handle index is not updated.

'''0xee01:''' Too many handles. Returned when the number of handles passed is > 0x40.

If the referenced thread is currently in a synchronization call ([[#svcWaitSynchronization]], [[#svcReplyAndReceive]] or [[#svcReplyAndReceiveLight]]), that call will be interrupted and return 0xec01.
If that thread is not currently executing such a synchronization call, the next call to a synchronization call will return 0xec01.

This doesn't take force-pause (activity/debug pause) into account.

=== Result codes ===

'''0x0:''' Success. The thread was either interrupted or has had its flag set.

'''0xe401:''' Invalid handle. The handle given was either invalid or not a thread handle.

Size and CmdPtr must be 0x1000-aligned.

=== Result codes ===

'''0x0:''' Success.

'''0xcc01:''' CmdPtr is not 0x1000-aligned.

'''0xca01:''' Size is not 0x1000-aligned.

'''0xce01:''' KSessionRequest allocation failed (unlikely) or pointer buffer size exceeded.

If the process is attached, report the Break event. Then, if svcContinueDebugEvent didn't apply IgnoreException on the thread: if TPIDR_EL0 is 0, adjust ELR_EL1 to retry to svc instruction (and set TPIDR_EL0 to 1).

Otherwise, if bit31 in reason isn't set, perform crash reporting (see Exception Handling section below), if it doesn't terminate the process adjust ELR_EL1 as well.

This is like svcSetHeapSize except you can allocate heap at any address you'd like.

Uses current process pool partition.

If ReplyTarget is not zero, a reply from the TLS will be sent to that session.
Then it will wait until either of the passed sessions has an incoming message, is closed, a passed port has an incoming connection, or the timeout expires.
If there is an incoming message, it is copied to the TLS.

If ReplyTarget is zero, the TLS should contain a blank message. If this message has a C descriptor, the buffer it points to will be used as the pointer buffer. See [[IPC_Marshalling#IPC_buffers]]. Note that a pointer buffer cannot be specified if ReplyTarget is not zero.

After being validated, passed handles will be enumerated in order; even if a session has been closed, if one that appears earlier in the list has an incoming message, it will take priority and a result code of 0x0 will be returned.

=== Result codes ===

'''0x0:''' Success. Either a session has an incoming message or a port has an incoming connection. HandleIndex is set appropriately.

'''0xea01:''' Timeout. No handles were signalled before the timeout expired. HandleIndex is not updated.

'''0xf601:''' Port remote dead. One of the sessions has been closed. HandleIndex is set appropriately.

== svcMapPhysicalMemoryUnsafe ==
Same as [[#svcMapPhysicalMemory]] except it always uses pool partition 0.

== svcCreateCodeMemory ==
Takes an address range with backing memory to create the code memory object.

The memory is initially memset to 0xFF after being locked.

== svcControlCodeMemory ==
Maps the backing memory for a Code memory object into the current process.

For [[#CodeMemoryOperation|CodeMemoryOperation_MapOwner]], memory permission must be RW-.

For [[#CodeMemoryOperation|CodeMemoryOperation_MapSlave]], memory permission must be R-- or R-X.

Operations [[#CodeMemoryOperation|CodeMemoryOperation_UnmapOwner/CodeMemoryOperation_UnmapSlave]] unmap memory that was previously mapped this way.

This allows one "secure JIT" process to map the code memory as RW-, and the other "slave" process to map it R-X.

[5.0.0+] Error 0xE401 is now returned when the process owner of the Code memory object is the same as the current process.

Read/write IO registers with a hardcoded whitelist. Input address is physical-address and must be aligned to 4.

rw_mask is 0 for reading and 0xffffffff for writing. You can also write individual bits by using a mask value.

You can only write to registers inside physical pages 0x70019000 (MC), 0x7001C000 (MC0), 0x7001D000 (MC1), and they all share the same whitelist.

The whitelist is same for writing as for reading.

The whitelist is:

0x054, 0x090, 0x094, 0x098, 0x09c, 0x0a0, 0x0a4, 0x0a8, 0x0ac, 0x0b0, 0x0b4, 0x0b8, 0x0bc, 0x0c0, 0x0c4, 0x0c8, 0x0d0, 0x0d4, 0x0d8, 0x0dc, 0x0e0, 0x100, 0x108, 0x10c, 0x118, 0x11c, 0x124, 0x128, 0x12c, 0x130, 0x134, 0x138, 0x13c, 0x158, 0x15c, 0x164, 0x168, 0x16c, 0x170, 0x174, 0x178, 0x17c, 0x200, 0x204, 0x2e4, 0x2e8, 0x2ec, 0x2f4, 0x2f8, 0x310, 0x314, 0x320, 0x328, 0x344, 0x348, 0x370, 0x374, 0x37c, 0x380, 0x390, 0x394, 0x398, 0x3ac, 0x3b8, 0x3bc, 0x3c0, 0x3c4, 0x3d8, 0x3e8, 0x41c, 0x420, 0x424, 0x428, 0x42c, 0x430, 0x44c, 0x47c, 0x480, 0x484, 0x50c, 0x554, 0x558, 0x55c, 0x670, 0x674, 0x690, 0x694, 0x698, 0x69c, 0x6a0, 0x6a4, 0x6c0, 0x6c4, 0x6f0, 0x6f4, 0x960, 0x970, 0x974, 0xa20, 0xa24, 0xb88, 0xb8c, 0xbc4, 0xbc8, 0xbcc, 0xbd0, 0xbd4, 0xbd8, 0xbdc, 0xbe0, 0xbe4, 0xbe8, 0xbec, 0xc00, 0xc5c, 0xcac

[2.0.0+] Whitelist was extended with 0x4c4, 0x4c8, 0x4cc, 0x584, 0x588, 0x58c.

[2.0.0+] The IO registers in range 0x7000E400 (PMC) size 0xC00 skip the whitelist, and do a TrustZone call using [[SMC]] Id1 0xC3000008(ReadWriteRegister).

[4.0.0+] Access to the Memory Controller (0x70019000) also uses smcReadWriteRegister.

Here is the whitelist imposed by that SMC, relative to the start of the PMC registers:

If hardware_breakpoint_id < 0x10, then it sets one of the AArch64 hardware breakpoints. Flags will go to DBGBCRn_EL1, and value to DBGBVRn_EL1. The only flags the user is allowed to set are those in the bitmask 0x7F01E1. Furthermore, the kernel will or it with 0x4004, in order to set various security flags to guarantee the watchpoints only triggers for code in EL0. If the user asks for a Breakpoint Type of ContextIDR match, the kernel shall use the given debug_handle to set DBGBVRn_EL1 to the ContextID of the debugged process.

If hardware_breakpoint_id is between 0x10 and 0x20 (exclusive), then it sets one of the AArch64 hardware watchpoints. Flags will go to DBGWCRn_EL1, and the value to DBGWVRn_EL1. The only flags the user is allowed to set are those in the bitmask 0xFF0F1FF9. Furthermore, the kernel will or it with 0x104004. This will set various security flags, and set the watchpoint type to be a Linked Watchpoint. This means that you need to link it to a Linked ContextIDR breakpoint. Check the ARM documentation for more information.

Note that hardware_breakpoint_id 0 to 4 match only to Virtual Address, while hardware_breakpoint_id 5 and 6 match against either Virtual Address, ContextID, or VMID. As such, if you are configuring a breakpoint to link for a watchpoint, make sure you use hardware_breakpoint_id 5 or 6.

For more documentation for hardware breakpoints, check out the AArch64 documentation for the [http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.ddi0488h/way1382455558968.html DBGBCRn_EL1 register] and the [http://infocenter.arm.com/help/topic/com.arm.doc.ddi0488h/way1382455560629.html DBGWCRn_EL1 register]

= Exception handling =
First of all, a function that might be called by synchronous exception handler and that is called by the SError handler fetches the exception info, adjusts PC, panics on exceptions taken from EL1, then dispatches the exception.

The dispatcher has two mutually exclusive exception reporting methods:
* by storing information at the start of the process's TLS memregion (TPIDRRO_EL0) and jumping back to the crt0
* by using KDebug

KDebug dispatching is used when at least one of the following conditions are met:
* SMC ConfigItem KernelMemConfig bit 1 is NOT set (it isn't on retail), unless: this is a software or hardware breakpoint, or a watchpoint, or [4.0.0+?] the process is attached and this is a Google PNaCl trap instruction (see LLVM source)
* FAR doesn't point to a valid address in mapped-readable CodeStatic memory (i.e. this is the case for NRO and JIT memory) or this is one of the following exceptions (it particular, that doesn't include FP exceptions occurring in CodeStatic memory):
** Uncategorized
** IllegalState
** SupervisorCallA32
** SupervisorCallA64
** PCAlignment
** SPAlignment
** SError
** BreakpointLowerEl
** SoftwareStepLowerEl (note: no way set single-step flag; not parsed)
** WatchpointLowerEl
** SoftwareBreakpointA32 (note: not parsed)
** SoftwareBreakpointA64 (note: not parsed)

In all other cases the userland-handled exception path is taken.

KDebug path:

If the process is attached, the exception is reported to the KDebug. If the thread was continued using flag IgnoreExceptions, it returns from the exception as if nothing happened.

If the latter is not the case, or if the process isn't attached, proceed to [2.0.0+] crash reporting (or in [1.0.0] just terminate the process):
if EnableDebug is set, and depending on the process state (more than one crash per process isn't permitted) it may signal itself with ProcessState_Crashed so that PM asks NS to start creport so that creport attaches to it and reports the crashes. Otherwise, just terminate.

Userland reporting path and svcReturnFromException:

In that case, after storing the regs in the TLS, the exception handler returns to the application's crt0 (entrypoint), with X0=<error description code> (see below) and X1=SP=frame=<stack top> (see above)

|-
|}

(During normal app boot the process is invoked with X0=0 and X1=main_thread_handle. The crt0 of retail apps determines whether to boot normally or handle an exception if X0 is set to 0 or not)

The application is supposed to promptly update the contents of elr_el1 to a user handler (and any other regs it sees fit) and call svcReturnFromException (error code) to call that handler. The latter is then expected to promptly abort the program.

svcReturnFromException updates the contents of the kernel stack frame with what the user provided in the TLS structure, sets TPIDR_EL0 to 1, then:
* if the provided error code is 0, gracefully pivots and returns from exception
* if it is not, replays the exception and pass it to the KDebug (see above). One can pass 0x10001 to prevent process termination. If the process is attached, this also prevents crash-collection/termination (different from the exception handler behavior)

If an exception occurs from the above user handler, the entire exception handling process will repeat with the new exception.

Note that if a thread that wasn't faulting calls svcReturnFromException, it signals an "invalid syscall" exception

Note that [[SMC|IsDebugMode]] is not used during exception-handling, except for enabling printing a message to UART-A. This UART code causes a system-hang on retail (likely due to a loop that doesn't exit). This printing doesn't seem to run when the process is attached for debugging?

Takes a storageID, a pid, a titleID, a 0x1C type-A buffer for the [[NPDM#FS_Access_Header| FS Access Header]], and a 0x2C type-A buffer for the [[NPDM#FS_Access_Control| FS Access Control]]

Final FS permissions are stored as (ACI0_perms & ACID_perms). Will panic(svcBreak) when buffer sizes from ipc-rawdata are invalid.

== UnregisterProgram ==
Takes a pid. Removes registered FS permissions for that PID.

== SetEnabledProgramVerification ==
Seems to sets a global flag to inputval & 1.

When the flag is zero, it will set ret=0 instead of ret={error} when verifying the fixed-key [[NPDM]] ACID signature fails. This also skips verifying the [[NCA_Format|NCA Header]] signature using the ACID key. Note that if verifying the fixed-key ACID signature is successful, and verifying the ACID-key NCA header signature fails, it will throw an error and abort.

== Permissions ==
Every time permissions are checked, the process registration [[#fsp-pr]] is loaded using the session processID. The permission data is populated with data from the [[NPDM]].

If the processID is <= 6 (which happens only for built-in sysmodules), it will use a hardcoded registration data. The default mask in this case is 0x8000000000000000.

Note that the functions check whether or not at least one bit is set in the mask. This means that, you don't need to set 0xFFFFFFFFFFFFFFFF to get all permissions: it suffices to set 0x8000000000000000.

If the code were to request an invalid input type, panic. But this never happens.

== OpenFileSystem ==
Takes a type-0x19 input buffer (ContentPath) and a [[#FileSystemType]] as parameters. Returns an [[#IFileSystem]].

[2.0.0+] This function was removed.

== SetCurrentProcess ==
Takes a pid-descriptor.

== OpenFileSystemWithPatch ==
Takes an input [[#FileSystemType]] and an u64 title-id. Returns an [[#IFileSystem]].

Web-applet loads the [[#FileSystemType]] (which must be '''ContentManual''') from u32_table[inparam].

Note: web-applet strings refer to both this cmd and [[#OpenFileSystemWithId]] as "MountContent", but official nn_sf_sync symbols use "OpenXX" names.

== OpenFileSystemWithId ==
Takes a type-0x19 input buffer, an [[#FileSystemType]] and an u64 title-id. Returns an [[#IFileSystem]].

The [[#IFileSystem]] must be '''ContentMeta''' if the NCA type is 0 (control).

The input buffer is the output string path from [[NS_Services#GetApplicationContentPath|GetApplicationContentPath]].

May return errors when attempting to access NCA-paths for an update-title with a gamecard, when the gamecard isn't inserted. May return error 0x7D402 in some cases with update-titles. Non-val2 in32 values with NCA-type1 are unusable, even for normal titles.

The official "MountApplicationPackage" func uses this with in64=0 and [[#FileSystemType]] '''ApplicationPackage'''.

After the [[#FileSystemType]] specific permissions are checked, it then gets the func retval for permissions-type 0x25 and func0.

When [[#FileSystemType]] is '''ContentMeta''', it uses in64=0xffffffffffffffff internally, otherwise it checks if in64 is set to 0xffffffffffffffff then throws an error if so. When the in64 used internally is not 0xffffffffffffffff, it's compared with the NCA titleID, then an error is thrown on mismatch.

== OpenBisFileSystem ==
Takes a type-0x19 input buffer string and a u32 [[Flash_Filesystem|Bis partitionID]]. Official user-process code sets instr[0] = 0 normally. Returns an [[#IFileSystem]].

Only partitionIDs for FAT partitions are usable with this, otherwise error 0x2EE202 is returned. Seems to be about the same as [[#OpenBisStorage]] except this mounts the partition filesystem instead of allowing direct access to the partition sectors.

== OpenBisStorage ==
Takes a u32 partition ID, returns 0x2EE202 for partitions which do not exist, 0x320002 for partitions which cannot be opened and a valid [[#IStorage]] handle otherwise.

== InvalidateBisCache ==
Seems to invalidate the Bis cache for MBR/GPT after overwriting that data via the OpenBisStorage IStorage. Used by [[SystemInitializer]].

== DeleteSaveDataFileSystem ==
Takes an input u64.

== CreateSaveDataFileSystem ==
Takes a 0x40-byte Save-struct entry, a 0x40-byte SaveCreate-struct entry, and a 0x10-byte input struct.

Only the first 0x5-bytes in the 0x10-byte struct are initialized: all-zero when automatically creating savedata during savecommon mount by official user-processes. In the dedicated save-creation code in official user-processes: +0 u32 = 0x40060, +4 u8 = 1.

Creates regular savedata.

== CreateSaveDataFileSystemBySystemSaveDataId ==
Takes a 0x40-byte Save-struct entry and a 0x40-byte SaveCreate-struct entry.

Creates savedata in the SYSTEM [[Flash_Filesystem|NAND]] partition.

== OpenGameCardStorage ==
Takes two input u32s (gamecard handle, partition ID), and returns an [[#IStorage]] for the [[Gamecard_Format|partition]].

== OpenGameCardFileSystem ==
Takes two input u32s, with the second u32 located at +4 in rawdata after the first u32. Returns an [[#IFileSystem]].

Mounts a [[Gamecard_Partition|gamecard partition]].

== OpenSaveDataFileSystem ==
Takes an input u8 [[#SaveDataSpaceId]] and a 0x40-byte Save-struct entry. Official user-process code is only known to use value 1 for the u8.

Returns an [[#IFileSystem]].

Permissions aren't checked until the specified save is successfully found.

Only one process (specifically only one [[#IFileSystem]] session) can mount a given savedata at any given time (this includes SystemSaveData).

== OpenSaveDataFileSystemBySystemSaveDataId ==
Takes an input u8 [[#SaveDataSpaceId]] and a 0x40-byte Save-struct entry. Web-applet only uses value0 for the input u8.

Returns an [[#IFileSystem]].

Mounts savedata in the SYSTEM [[Flash_Filesystem|NAND]] partition.

== ReadSaveDataFileSystemExtraDataBySaveDataSpaceId ==
Takes an input u8 [[#SaveDataSpaceId]], an input u64 saveID, and a type-0x6 output buffer containing the [[#SaveDataFileSystemExtraData]].

== ReadSaveDataFileSystemExtraData ==
Takes an input u64 saveID and a type-0x6 output buffer containing the [[#SaveDataFileSystemExtraData]].

== OpenSaveDataInfoReader ==
No input, returns an output [[#ISaveDataInfoReader]].

== OpenSaveDataInfoReaderBySaveDataSpaceId ==
Takes an input u8 [[#SaveDataSpaceId]], returns an output [[#ISaveDataInfoReader]].

== OpenContentStorageFileSystem ==
Takes a [[#ContentStorageId]]. Invalid values return 0x2EE202.

Returns an [[#IFileSystem]] with NCA files. The read data from these files is identical to the data read by [[NCM_services#ReadContentIdFile]].

== OpenDataStorageByDataId ==
Takes a [[#StorageId]] and a TitleID.

Returns a [[IPC_Marshalling#Domain_message|domain object ID]] implementing the [[#IStorage]] interface for data archives.

== OpenDeviceOperator ==
This command returns a session to a port implementing the [[#IDeviceOperator]] interface.

== OpenSdCardDetectionEventNotifier ==
This command returns a session to a port implementing the [[#IEventNotifier]] interface.

== OpenGameCardDetectionEventNotifier ==
This command returns a session to a port implementing the [[#IEventNotifier]] interface.

== VerifySaveDataFileSystem ==
Takes an unknown input u64 and a type-0x6 output buffer.

The input u64 high-byte must be non-zero, otherwise an [[Error_codes|error]] is returned(0xE02).

== GetSaveDataCommitId ==
Takes an input u8 and u64, returns an output u64.

== SetSdCardEncryptionSeed ==
Takes in the 0x10 byte SD card encryption seed, and loads it into FS-module state.

[[NS_Services|NS]]-module reads the 0x10 bytes from SdCard:/Nintendo/Contents/private, and compares them to the first 0x10 bytes of the ns_appman:/private (in [[Flash_Filesystem#System_Savegames|system savedata]] 0x8000000000000043). If they match, NS calls this command using bytes 0x10-0x20 from ns_appman:/private. The rest of this file (0x1F0 bytes total) is (usually/always?) all-zero.

== SetGlobalAccessLogMode ==
Takes an input u32.

== GetGlobalAccessLogMode ==
Returns an output u32.

GlobalAccessLogMode is normally 0.

== OutputAccessLogToSdCard ==
Takes a type-0x5 input buffer.

The input buffer is the string to output to the log. User-processes normally include a newline at the end.

User-processes only use this when the value previously loaded from [[#GetGlobalAccessLogMode]] has bit1 set.

When bit1 in GlobalAccessLogMode is clear, FS-module will just return 0 for OutputAccessLogToSdCard. However even with that set the log doesn't show up SD, unknown why.

The input buffer is written to the "$FsAccessLog:/FsAccessLog.txt" file, where "$FsAccessLog" is the SD-card mount-name. It's written to the current end of the file(appended).

= IFileSystem =
This is "nn::fssrv::sf::IFileSystem".

There are two main implementations of this interface:

* '''RomFS''': Filesystem implementation statically linked in the binary. Uses an [[#IStorage]] interface as underlying raw device.
* '''IPC proxy''': Used for all non-RomFS filesystems. In this case, actual filesystem implementation is in the FS process.

== GetEntryType ==
Takes a type-0x9 input buffer for the path and returns [[#DirectoryEntryType]] as an output u32.

== OpenFile ==
Takes a type-0x19 input buffer for the path, and an u32 '''mode'''. '''mode''' controls how the file is opened, based on which bits are set:

* When bit 0 is set, the file is Readable: you can use the Read operation.
* When bit 1 is set, the file is Writable: you can use the Write operation.
* When bit 2 is set, the file is Appendable: unless this bit is set, you will not be able to write beyond the end of a file (such writes will result in an error 0x307202)

== OpenDirectory ==
Takes a type-0x9 input buffer for the path and an u64 '''filter_flags'''. '''filter_flags''' controls what type of entries are read by the [[#IDirectory]]: bitmask 0x1 = directories, bitmask 0x2 = files.

== Commit ==
Like [https://3dbrew.org/wiki/FS:ControlArchive 3DS], this has to be used after writing to savedata for the changes to take affect.

== GetFreeSpaceSize ==
Takes a type-0x9 input buffer for the path and returns an output byte-size u64 for the total free space with this FS.

== GetTotalSpaceSize ==
Takes a type-0x9 input buffer for the path and returns an output byte-size u64 for the total space available with this FS(free+used).

== CleanDirectoryRecursively ==
Takes a type-0x9 input buffer for the path and clears the contents of the directory specified in the path.

== GetFileTimeStampRaw ==
Takes a type-0x19 input buffer for the path and returns a 0x20-byte struct. This contains 3 u64s and an u8.
