StartFirmwareUpdate

Takes a total of 0x20-bytes of input, 2 handles, and returns an output handle.

[3.0.0+] Now takes a total of 8-bytes of input, and no longer uses any input/output handles.

GetFirmwareVersion

Takes a total of 8-bytes of input, and returns a total of 4-bytes of output.

[3.0.0+] Now returns an additional 0xC-bytes of output.

GetDestinationFirmwareVersion

Takes a total of 8-bytes of input, and returns a total of 4-bytes of output.

[3.0.0+] Now returns an additional 0xC-bytes of output.

DiscardFirmwareInfoCacheForRevert

Takes a total of 8-bytes of input, and returns a total of 5-bytes of output.

[3.0.0+] No input/output.

UpdateControllerColor

Takes two input u32s for the colors, an input u64 UniquePadId, and no output.

A state flag must be clear, otherwise an error is thrown. Afterwards, this flag is set.

Sends the spi-write subcommand to the specified controller, for writing the color data. This writes to offset 0x6050 size 0x6, where the first 3-bytes are from the first u32 and the remaining 3-bytes are from the second u32.

UpdateDesignInfo

Takes 4 input u32s for the colors, an input u8, an input u64 UniquePadId, and no output.

A state flag must be clear (same as #UpdateControllerColor), otherwise an error is thrown. Afterwards, this flag is set.

Sends the spi-write subcommand to the specified controller, for writing to offset 0x6050 size 0xD. The first 3-bytes from each u32 is used for the spi-write-data, with the u8 being copied immediately afterwards the color data.

AttachHdlsWorkBuffer

Takes an input TransferMemory handle and an u64 for the TransferMemory size, no output.

Official user-processes use TransferMemory size=0x1000 and permissions=RW.

This TransferMemory is used as input/output by the other Hdls commands.

Hdls is for virtual HID controllers.

ReleaseHdlsWorkBuffer

No input/output.

DumpHdlsNpadAssignmentState

No input/output.

After using this cmd, the output #HdlsNpadAssignment is located at tmem+0.

DumpHdlsStates

No input/output.

After using this cmd, the output #HdlsStateList struct is located at tmem+0.

ApplyHdlsNpadAssignmentState

Takes an input u8 bool, no output.

Prior to using this cmd, the input #HdlsNpadAssignment is written to tmem+0 by the user-process.

ApplyHdlsStateList

No input/output.

Prior to using this cmd, the input #HdlsStateList is written to tmem+0 by the user-process.

The #HdlsState will be applied for each HdlsHandle. If a HdlsHandle is not found, code similar to #AttachHdlsVirtualDevice will run with the #HdlsDeviceInfo, then it will continue with applying state with the new device.

AttachHdlsVirtualDevice

Takes an #HdlsDeviceInfo, returns a 8-byte HdlsHandle.

DetachHdlsVirtualDevice

Takes an input 8-byte HdlsHandle, no output.

SetHdlsState

Takes an input #HdlsState and an input 8-byte HdlsHandle, no output.

This is "nn::hid::system::NotificationLedPattern".

This is a 0x48-byte struct.

The above descriptions in the table are based on the info from here.

argdata in the subcommand is initialized as follows: ((u8*)cmd_argdata)[pos] = u8_in[pos2] | u8_in[pos3]<<4; Hence, 4bits from pairs of 2-bytes of the input struct are combined to write to the subcommand. Only the low 4bits of each used byte in the struct is used. This is written to stack initially, then copied to the actual cmd_argdata (the data immediately following the subcommandID byte). There's a total of 0x1B-bytes of cmd_argdata initialized from this.

The layout of cmd_argdata is as follows:

Offset	Size	Description
0x0	0x1B	See above.
0x1B	0xB	Cleared to zero.
0x26	0x5	Unused
0x2B	0x8	Set to an input value, which is hard-coded 0.
0x33	0x2	Set to value 0.
0x35	0x1	Set to value 1.

IReadSession

This is "nn::ahid::IReadSession".

Cmd	Name	Notes
0

Cmd0 uses PostBufferAsync etc with the INPUT endpoint. The size must be <=0x1000. The actual transfer size is returned in an output u64. The data is copied from the tmpbuf to the output buffer using the actual-transfer-size.
