ListDisplays
Takes a type-0x6 output buffer containing the array of #DisplayInfo output entries. Returns an output u64.
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.
OpenLayer
Takes a PID-descriptor, a type-0x6 buffer for the output #NativeWindow, a #DisplayName(which was previously used with #OpenDisplay), an u64 ExternalLayerId, and an u64 AppletResourceUserId. Returns an output u64 NativeWindow_Size.
Official user-processes use an ExternalLayerId stored in a global state field if non-zero, otherwise:
- When AppletResourceUserId==0, #CreateStrayLayer is used instead of the OpenLayer cmd.
- When AppletResourceUserId!=0, {unknown cmd} is used and the output from that is used for ExternalLayerId with the OpenLayer cmd.
CloseLayer
Takes an input u64.
CreateStrayLayer
Takes a type-0x6 buffer for the output #NativeWindow, an u32, and an u64. Returns two output u64s: ExternalLayerId and NativeWindow_Size.
DestroyStrayLayer
Takes an input u64.
SetLayerScalingMode
Takes an input u32("ScalingMode") and u64.
GetIndirectLayerImageMap
Takes a PID-descriptor, an type-0x46 buffer, and four u64s(last u64 is AppletResourceUserId). Returns two output u64s.
GetIndirectLayerImageCropMap
Takes a PID-descriptor, an type-0x46 buffer, four floats, four u64s(last u64 is AppletResourceUserId). Returns two output u64s. The floats are stored immediately after each other(32bits).
GetIndirectLayerImageRequiredMemoryInfo
Takes two input u64s. Returns two output u64s.
GetDisplayVsyncEvent
Takes an input u64 DisplayId and returns a handle.
GetDisplayVsyncEventForDebug
Takes an input u64 DisplayId and returns a handle.

DisplayInfo
This is a 0x60-byte structure.
DisplayName
This is a 0x40-byte block: a NUL-terminated string.
NativeWindow
Max size of this buffer is 0x100-bytes(outbuf size used by official user-processes). Parsed("Deserialize...") by a function called by the code described under #OpenLayer, which executes code with Android symbols.
