AMDGPU heavily relies on ring buffers to manage its components; as a
result, it has an elaborate mechanism of operation with multiple details
around it. This commit introduces new documentation on ring buffers,
detailing their management and expanding the explanation of Enforce
isolation. Finally, this commit also adds the documentation available in
the amdgpu_ring.c file to it.

Documentation/gpu: Create a GC entry in the amdgpu documentation2025-04-07T19:18:35+00:00Rodrigo Siqueirasiqueira@igalia.com2025-03-25T17:18:46+00:00urn:sha1:e7aaa5fbf4fc1aa9c348075aab9bf054727f025f
GC is a large block that plays a vital role for amdgpu; for this reason,
this commit creates one specific page for GC and adds extra information
about the CP component.

Documentation/gpu: Create a documentation entry just for hardware info2025-04-07T19:18:35+00:00Rodrigo Siqueirasiqueira@igalia.com2025-03-25T17:18:44+00:00urn:sha1:c6a1c23d1041f7a5f8f259face14212c6ce4f1a8
The APU and dGPU tables are hidden in the driver misc info, which makes
it hard to find specific hardware info when users need it. This commit
creates a single page for this information and adds it to the top of the
amdgpu list to improve searchability.

Documentation/gpu: Change index order to show driver core first2025-04-07T19:18:35+00:00Rodrigo Siqueirasiqueira@igalia.com2025-03-25T17:18:43+00:00urn:sha1:5acd17d6d14ec1112a6427e7c02569cba6c46f2d
Since driver-core has an overview of the AMD GPU hardware structure, it
makes more sense to keep it first. This commit move driver-core up in
the index list.

drm/amdgpu: Add documentation for enforce isolation feature2024-11-08T16:45:29+00:00Srinivasan Shanmugamsrinivasan.shanmugam@amd.com2024-11-06T13:55:50+00:00urn:sha1:5954cfa812f4f5850cf0246c499a6dc256196b01
This feature enables process isolation on the graphics engine by
serializing access to it and adding a cleaner shader which clears LDS
(Local Data Store) and GPRs (General Purpose Registers) between jobs.
