drm/gpusvm: Fix kernel-doc

2025-03-13T03:53:47Z

Due to wrong `.. kernel-doc` directive in Documentation/gpu/rfc/gpusvm.rst the documentation was actually not parsing anything from drivers/gpu/drm/drm_gpusvm.c. This fixes the kernel-doc include and all warnings/errors created when doing so.

gpu: nova-core: add initial documentation

2025-03-09T18:24:29Z

Add the initial documentation of the Nova project. The initial project documentation consists out of a brief introduction of the project, as well as project guidelines both general and nova-core specific and a task list for nova-core specifically. The task list is divided into tasks for general Rust infrastructure required by the project, tasks regarding GSP enablement and firmware abstraction, general GPU driver tasks as well as tasks related to external API design and test infrastructure.

Documentation/gpu: Add acronyms for some firmware components

2025-02-25T16:43:58Z

Users can check the file "/sys/kernel/debug/dri/0/amdgpu_firmware_info" to get information on the firmware loaded in the system. This file has multiple acronyms that are not documented in the glossary. This commit introduces some missing acronyms to the AMD glossary documentation. The meaning of each acronym in this commit was extracted from code documentation available in the following files: - drivers/gpu/drm/amd/amdgpu/gfx_v7_0.c - drivers/gpu/drm/amd/include/amd_shared.h Changes since v1: - Expand acronym meanings based on Alex Deucher suggestions.
