In order to explain the name clean-ups in GSP RPC routines, a kernel doc to explain the memory layout and terms is required. Add a kernel doc to introduce the GSP RPC.

drm/nouveau NVIDIA GPU Driver
|
|
===============================
|
|
|
|
The drm/nouveau driver provides support for a wide range of NVIDIA GPUs,
|
|
covering GeForce, Quadro, and Tesla series, from the NV04 architecture up
|
|
to the latest Turing, Ampere, Ada families.

NVKM: NVIDIA Kernel Manager
|
|
===========================
|
|
|
|
The NVKM component serves as the core abstraction layer within the nouveau
|
|
driver, responsible for managing NVIDIA GPU hardware at the kernel level.
|
|
NVKM provides a unified interface for handling various GPU architectures.
|
|
|
|
It enables resource management, power control, memory handling, and command
|
|
submission required for the proper functioning of NVIDIA GPUs under the
|
|
nouveau driver.
|
|
|
|
NVKM plays a critical role in abstracting hardware complexities and
|
|
providing a consistent API to upper layers of the driver stack.
