* cmd210: User-processes use hard-coded size 0x88 for the type-0x15 buffer.
 +
* cmd1106/1107: User-processes use hard-coded sizes 0x400 and 0x404 for the first/second type-0x15 buffers.
 +
* cmd1201/1202/1203: These are only usable when the previously loaded value from [[Settings_services|set:sys GetDebugModeFlag]] is set.
 +
 +
The only caps:sc commands used by [[GRC_services|GRC]] are: 1101, 1106, and 1107.
 +
 +
[8.0.0+] Cmd210 and cmd1004 now takes an additional type-0x15 input buffer.
 +
 +
== CaptureRawImage ==
 +
Takes a type-0x46 output buffer, an input u32 '''layer_stack''', 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.
 +
 +
Stubbed with [5.0.0+], where it now returns error 0x7FECE.
 +
 +
== CaptureRawImageWithTimeout ==
 +
Calls the same internal func as [[#CaptureRawImage]], where the last param is an additional cmd input u64 instead of hard-coded value 0x5f5e100.
 +
 +
Stubbed with [5.0.0+], where it now returns error 0x7FECE.
 +
 +
== SetupOverlayMovieThumbnail ==
 +
Takes two input u64s '''width'''/'''height''', a 0x18-byte input struct, and two type-0x46 output buffers.
 +
 +
For the input struct, [[GRC_services|GRC]] uses the output from [[Capture_services|caps:c]] cmd2101.
 +
 +
'''width'''/'''height''' must be 1280x720. The first buffer address must be 0x400-byte aligned. The size of the first buffer must be at least '''width'''*'''height''', and must be aligned to 0x20000-bytes.
 +
 +
The requirements for the second buffer address/size are the same as the first buffer, except the minimum size is ('''width'''*'''height''')/2.
 +
 +
== Cmd1106 ==
 +
Takes a 0x40-byte input struct, two input u64s '''width'''/'''height''', a 0x18-byte input struct, two type-0x15 input buffers, a type-0x6 output buffer, and two type-0x46 output buffers, returns 3 output u64s.
 +
 +
'''width'''/'''height''' have same requirements as [[#SetupOverlayMovieThumbnail]]. The size of the type-0x6 buffer must be at least 0x7D000. The requirements for the type-0x46 buffers are the same as [[#SetupOverlayMovieThumbnail]].
 +
 +
[5.0.0+] Now takes a total of 0x68-bytes of input instead of 0x30.
 +
 +
== Cmd1107 ==
 +
Takes a 0x40-byte input struct, two input u64s '''width'''/'''height''', a 0x18-byte input struct, two type-0x15 input buffers, a type-0x6 output buffer, and a type-0x45 input buffer, returns 3 output u64s.
 +
 +
'''width'''/'''height''' have same requirements as [[#SetupOverlayMovieThumbnail]]. The size of the type-0x6 buffer must be at least 0x7D000. The size of the type-0x45 buffer must be at least 0x384000.
 +
 +
[5.0.0+] Now takes a total of 0x68-bytes of input instead of 0x30.

* "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).

Takes an input u32 boolean, and an u64 DisplayId.

== GetDisplayResolution ==
 +
Takes an input u64 DisplayId and returns two output s64s: width and height. Official sw copies these to s32 output fields.
 +
 
 +
== 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.

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

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

 +
Takes a PID-descriptor, an type-0x46 buffer, two s64s width/height, then two u64s: <output from [[AM_services|AM]] GetIndirectLayerConsumerHandle>, and [[AM_services|AppletResourceUserId]]. Returns two output s64s, which are copied to output u64s by official sw.
 +
 
 +
Official sw sets the width/height using input s32s.
 +
 
 +
Calls the same func as [[#GetIndirectLayerImageCropMap]] internally, with the input floats set to 0.0f, then 1.0f for the rest.
 +
 
 +
== 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 s64s: width and height. Returns two output s64s, which are copied to output u64s by official sw. First field is the buffer size to use with the ImageMap cmds, second field is the buffer address alignment for those cmds.
 +
 
 +
Official sw sets the width/height using input s32s.

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

This is a 0x60-byte structure.

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

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

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]].

This normally contains the following:

 +

 +
|-
 +
| 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]].
