Applet Manager services

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.

appletAE

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

Cmd	Name	Notes
100	OpenSystemAppletProxy	Returns an #ISystemAppletProxy.
200	OpenLibraryAppletProxyOld ([1.0.0-2.3.0] OpenLibraryAppletProxy)	Returns an #ILibraryAppletProxy.
201	[3.0.0+] #OpenLibraryAppletProxy	Returns an #ILibraryAppletProxy.
300	OpenOverlayAppletProxy	Returns an #IOverlayAppletProxy.
350	OpenSystemApplicationProxy	Returns an #IApplicationProxy.

410	[6.0.0+] #GetSystemAppletControllerForDebug
450	[19.0.0+] #GetSystemProcessCommonFunctions
1000	[6.0.0+] #GetDebugFunctions

All of these Open*Proxy 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.

OpenLibraryAppletProxyOld eventually calls the same func as #OpenLibraryAppletProxy, except that the #AppletAttribute is all-zero.

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

The 01000000000010XX system 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 reserved input u64(official user-processes use hard-coded value 0), a PID,a process copy-handle(cur-proc handle alias), and a type-0x15 input buffer containing an #AppletAttribute.

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

CreateSelfLibraryAppletCreatorForDevelop

Takes a PID and an input u64 pid_placeholder, returns an #ILibraryAppletCreator.

The cached value loaded from Settings_services#GetDebugModeFlag must be 1, otherwise an error is returned.

The cached value loaded from system-setting am.debug!dev_function must be set to 0x1 with size 0x1, otherwise an error is returned.

GetSystemAppletControllerForDebug

No input, returns an #ISystemAppletControllerForDebug.

The cached value loaded from system-setting am.debug!dev_function must be set to 0x1 with size 0x1, and various state checks must pass, otherwise 0 is returned with no output interface.

GetSystemProcessCommonFunctions

No input. Returns an #ISystemProcessCommonFunctions.

GetDebugFunctions

No input, returns an #IDebugFunctions.

The cached value loaded from system-setting am.debug!dev_function must be set to 0x1 with size 0x1, otherwise 0 is returned with no output interface.

This is similar to #LaunchSystemApplet, except this uses ns LaunchLibraryApplet with a ProgramId from global state.

The global state field is initialized elsewhere with the value of system-setting am.debug!starter_id, defaulting to ProgramId 0100000000001012 (starter) if not available.

PopRequestLaunchApplicationForDebug

Takes a type-0x6 output buffer containing an array of u128 userIDs, returns an output ApplicationId and an output s32 total_userIDs.

The total entries in the userID buffer must be >= {total userIDs in state}.

When the cached value loaded from Settings_services#GetDebugModeFlag is 0 this will just set the bool to 0. Otherwise, the bool is loaded using data from system-setting am.debug!disable_force_terminate_application.

LaunchDevMenu

No input/output.

The cached value loaded from Settings_services#GetDebugModeFlag must be 1, otherwise an error is returned.

Uses ns LaunchDevMenu.

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):

• 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.

ClearUserChannel

No input/output.

Clears the UserChannel used by #UnpopToUserChannel.

UnpopToUserChannel

Takes an input #IStorage, no output.

The input storage is pushed to the UserChannel. This is the same channel used by #LaunchParameterKind value 1.

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.

Gets the ProgramIndex of the Application which launched this title. The output ProgramIndex is -1 when there was no previous title.

EnableApplicationAllThreadDumpOnCrash

Takes an input u8 bool, no output.

This is used by sdknso during applet-application initialization. A separate thread is setup where event-waiting is handled. When the Event is signaled, official sw will Abort.

SetDelayTimeToAbortOnGpuError

Takes an input s64 "nn::TimeSpan", no output.

GetFriendInvitationStorageChannelEvent

No input, returns an output Event handle with EventClearMode=0.

This is exposed by sdknso under nn::friends::. This returns a ptr to the cached Event in global state, with the Event being loaded if not previously initialized.

TryPopFromFriendInvitationStorageChannel

No input, returns an output #IStorage.

This uses the same StorageChannel as #PushToFriendInvitationStorageChannel.

This is exposed by sdknso under nn::friends::. When the storage_size is <0x10, this returns false. data_size = storage_size-0x10; Then the first 0x10-bytes from storage are read to stack, which is later copied to the output Uid on success prior to returning. Then the storage is read into the specified output buffer with storage-offset 0x10, where the size is size = data_size > buf_size ? buf_size : data_size. Reading is skipped if size is zero. Afterwards the used size is written to an output param. On success, true is returned.

GetNotificationStorageChannelEvent

No input, returns an output Event handle with EventClearMode=0.

This is exposed by sdknso under nn::notification::. This returns a ptr to the cached Event in global state, with the Event being loaded if not previously initialized.

TryPopFromNotificationStorageChannel

No input, returns an output #IStorage.

This uses the same StorageChannel as #PushToNotificationStorageChannel.

This is exposed by sdknso under nn::notification::. The storage is read into the specified output buffer, where the size is size = storage_size > buf_size ? buf_size : storage_size. Reading is skipped if size is zero. Afterwards the used size is written to an output param.

GetHealthWarningDisappearedSystemEvent

No input, returns an output Event with EventClearMode=0.

SetHdcpAuthenticationActivated

Takes an input u8 bool, no output.

GetLaunchRequiredVersion

Takes an input ApplicationId, an u64, returns an output #LaunchRequiredVersion.

sdknso passes hard-coded value 0 for the u64.

SendServerMaintenanceOverlayNotification

Takes two input PosixTime, no output.

The second input value can optionally be 0.

GetLastApplicationExitReason

No input, returns an output s32.

CreateMovieWriter

Takes 8-bytes of input and a handle. Returns an #IMovieWriter.

This internally uses the GRC cmd to open an IMovieWriter. This is therefore not usable on NX since that cmd is stubbed.

StartContinuousRecordingFlushForDebug

Takes an input s64 nanoseconds-value, returns an output Event handle with autoclear=false.

The cached value loaded from system-setting am.debug!dev_function must be set to 0x1 with size 0x1, otherwise an error is returned.

CreateMovieMaker

Takes an input u64 size and a TransferMemory handle, returns an #IMovieMaker.

Official sw retries using the cmd in a loop on error 0x8D4 with svcSleepThread(100000000) being used first.

Official sw uses permissions=None for the TransferMemory, with an user-specified buffer. The size of the buffer used by official sw is 0x6000000.

PrepareForJit

Takes no input. Launches the jit-sysmodule via ns LaunchLibraryApplet if it has not already been launched for the current application, storing a std::shared_ptr<> for jit-sysmodule process tracking object as an IApplicationFunctions member.

~IApplicationFunctions() includes:

   if (this->jit_process) {
       Terminate(this->jit_process);
       this->jit_process = nullptr;
   }

Thus the lifetime of the jit sysmodule is tied to the application which uses it, and each application gets its own fresh copy of the jit sysmodule.

AM can also optionally launch jit-sysmodule automatically if the NACP enables it.

IMovieWriter

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

This was added with [19.0.0+].

CreateLibraryApplet

Takes 2 input u32s #AppletId and #LibraryAppletMode, returns an #ILibraryAppletAccessor.

TerminateAllLibraryApplets

No input/output.

Stubbed with an ILibraryAppletCreator from #CreateSelfLibraryAppletCreatorForDevelop, just returns an error.

Terminates all LibraryApplets which were created by the current applet (or by the Application when used from the #IApplicationAccessor cmd).

AreAnyLibraryAppletsLeft

No input, returns an output u8 bool.

Stubbed with an ILibraryAppletCreator from #CreateSelfLibraryAppletCreatorForDevelop, just returns an error.

Gets whether any LibraryApplets (#ILibraryAppletAccessor) which were created by the current applet are still open (or by the Application when used from the #IApplicationAccessor cmd).

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 #AppletMessage).

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

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:

• RequestHomeMenu 5341 4d53 0100 0000 0200 0000 0100 0000 Returns to the main Home Menu, equivalent to pressing the HOME button.
• RequestJumpToSystemUpdate 5341 4d53 0100 0000 0b00 0000 0100 0000 Equivalent to entering "System Update" under System Settings. When leaving this, it returns to the main Home Menu.

Library Applets

This section documents library applet launching.

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

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 IStorage passed to applets should contain the common library applet arguments. This is populated by nn::la::CommonArgumentsWriter 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.

Notes

AM-sysmodule will only initialize pdm:ntfy / use pdm:ntfy service commands when the value from pm:bm GetBootMode is not 0x1 (Maintenance).

An object constructor also writes the output from pm:bm GetBootMode into the created object. A vfunc for this object checks whether this field is Maintenance: if so, it calls a vfunc then a func and returns. Otherwise after calling various (v)funcs, if required this eventually uses ommdisp cmd600.
