==== PostBufferAsync ====

Takes an input u32 '''size''', an input u64 '''buffer''', and an input u64 '''unk''', returns an output u32 '''xferId'''.

Takes an input u32 '''size''', an input u64 '''buffer''', and an input u64 '''id''', returns an output u32 '''xferId'''.

HID-sysmodule passes value 0 for the last u64.

Starts a data transfer with a single urb.

Starts a data transfer with a single urb.

The official sw func which uses this cmd and handles waiting on the Event passes value 0 for the '''id'''. The async version which exposes this cmd directly uses '''id''' from user input - the user funcs pass a value starting at 0 then increment it each time (for sending multiple requests at once, with 0 for the first request in this set of requests).

On newer sysvers the state fields setup by [[#CreateSmmuSpace]] are compared with '''buffer'''. If it's within bounds of the SmmuSpace (which won't be the case when [[#CreateSmmuSpace]] wasn't used), it will then verify that buffer+buffer_size is within bounds throwing an error otherwise. Note that a buffer from [[#CreateSmmuSpace]] can't be reused by another endpoint with PostBufferAsync.

==== BatchBufferAsync ====

==== BatchBufferAsync ====

Takes 3 input u32s ('''urbCount''', '''unk1''', and '''unk2'''), an input u64 '''buffer''' and u64 '''unk''', and a type-0x5 ([3.0.0+] type-0x21) input buffer, returns an output u32 '''xferId'''.

Takes 3 input u32s ('''urbCount''', '''unk1''', and '''unk2'''), an input u64 '''buffer''' and u64 '''id''', and a type-0x5 ([3.0.0+] type-0x21) input buffer, returns an output u32 '''xferId'''.

Where '''unk''' is the same as [[#PostBufferAsync_2|#PostBufferAsync]].

Where '''id''' is the same as [[#PostBufferAsync_2|#PostBufferAsync]].

This uses the same func internally as [[#PostBufferAsync_2|#PostBufferAsync]] except multiple urbs are specified by the user: the input buffer contains an array of u32s for the size of each urb, where '''urbCount''' is the total number of entries in this array. With [[#PostBufferAsync_2|#PostBufferAsync]] the last 2 params passed to the internal func are hard-coded to 0, while with this command it's '''unk1''' and '''unk2'''.
