== InitializeA ==
== InitializeGraphicsWithTransferMemory ==
Unofficial name.
 
Takes a TransferMemory handle, an input [[Applet_Manager_services#AppletResourceUserId|AppletResourceUserId]] and an input u64 '''TransferMemorySize'''. No output.
 
== InitializeGraphics ==
Unofficial name.
Unofficial name.


Sends current process handle, and struct { u64 aruid; u64 always_0x8000000000000005; u64 always_0; u64 always_0; u64 always_0; u64 svc_get_info_31_or_32_output; }.
Takes a Process handle, an input [[Applet_Manager_services#AppletResourceUserId|AppletResourceUserId]] and five input u64s. No output.
 
The first u64 appears to be a version ([19.0.0] 0x8000000000000001, [20.1.1] 0x8000000000000005), the last u64 is the output from new [[SVC#InfoType|InfoType]] 31 or 32 and the remaining u64s are all 0.


== InitializeB ==
== SetCurrentProcessHandle ==
Unofficial name.
Unofficial name.


Sends current process handle. No args. Sent directly after cmd4.
Takes a Process handle. No output.
 
Called directly after [[#InitializeGraphicsWithTransferMemory]] or [[#InitializeGraphics]].


== InitializeC ==
== StartGraphics ==
Unofficial name.
Unofficial name.


Sent directly after [[#InitializeB]].
No input/output.


== InitializeNvDrv2UserWithTransferMemory ==
Called directly after [[#SetCurrentProcessHandle]].
 
== PrepareGpuManagerSession ==
Unofficial name.

Called directly after [[#CreateGpuManagerSessionWithTransferMemory]] or [[#CreateGpuManagerSession]].
 
== StartGpuManagerSession ==
Unofficial name.
 
No input/output.
 
Called directly after [[#PrepareGpuManagerSession]].
 
== CreateGpuManagerSessionWithTransferMemory ==
Unofficial name.

[19.0.0] '''Version''' must be 2.
 
== CreateGpuManagerSession ==
Unofficial name.
 
Takes an input u64 '''Version'''. Returns a [[#GpuManagerSession]].

== CreateNvDrv2UserSessionWithTransferMemory ==
Unofficial name.
 
Takes a TransferMemory handle, an input u64 '''TransferMemorySize''' and an input u8. Returns an [[#INvDrv2User]].
 
== CreateNvDrv2UserSession ==
Unofficial name.
Unofficial name.


No input. Returns an [[#INvDrv2User]].

=== GetEventIdRange ===
Unofficial name.
No input. Returns two u32s '''EventIdMin''' and '''EventIdMax'''.
=== CreateEvent ===
Unofficial name.
Takes an input u32 '''EventId'''. Returns an output Event handle.
=== RequestGpuSession ===
Unofficial name.
Takes an input u32 '''EventId'''. No output.
'''EventId''' must have been previously passed to [[#CreateEvent]] and the returned Event handle will be signalled when the session is ready.
=== GetGpuSession ===
Unofficial name.
No input. Returns a [[#GpuSession]].
Called after [[#RequestGpuSession]] and the Event handle has been signalled.

==== CreateGpuMemory ====
Unofficial name.
Takes two input u64s '''MemoryAddressStart''' and '''MemoryAddressEnd''' and two u8s. Returns an output u32 '''GpuMemoryHandle'''.
The memory region between '''MemoryAddressStart''' and '''MemoryAddressEnd''' must have been passed to [[#SVC|SVC]] 0x80 with attribute 0x20.
==== DestroyGpuMemory ====
Unofficial name.
Takes two input u32s '''GpuMemoryHandle''' and '''EventId'''. No output.
The Event handle associated with '''EventId''' will be signalled when the memory is released.
