drm/xe: Move xe_uc_fw_abi.h to abi/

We aim to keep all pure ABI headers in the abi/ folder, but somehow we missed this file. Signed-off-by: Michal Wajdeczko Reviewed-by: Rodrigo Vivi Link: https://patch.msgid.link/20260527112608.22448-1-michal.wajdeczko@intel.com

Documentation/gpu: add dedicated documentation for Intel display

2026-05-11T07:30:13+00:00

Nowadays, the display support for drm/i915 and drm/xe is shared between the drivers, even though the code is located under drm/i915/display. The drm/i915 documentation has everything, including display topics, in one huge page, while the drm/xe documentation is well-organized but hardly mentions display. It's not great, to put it mildly. Split out the Intel display documentation to a dedicated directory, Documentation/gpu/intel-display. Also directly split the functionality/feature documentation to dedicated pages to keep the main index page high level and readable. We'll want to organize this further, but just sort them alphabetically for starters. Drop the boilerplate documentation sections that don't actually document anything. Cross-reference drm/i915, drm/xe, and intel-display.

drm/xe: Document GT statistics

2026-03-30T09:00:45+00:00

In the context of porting applications to SVM, the Xe GT statistics are used by application developers to validate expected behavior such as proper alignment, page fault count and migrations. As those statistics are made for kernel developers, they assume good understanding of driver internals, which is not always the case on the application side. Therefore, this commit documents the usage of GT statistics and clarifies the meaning of identifiers which correspond to the values exposed via debugfs. Documentation is close to identifiers declaration to make it easier to maintain when adding new entries in the future. v2: Fix page reclaim list (PRL) entries (Matthew Brost) Assisted-by: GitHub Copilot:claude-sonnet-4.6 Cc: Matthew Brost Reviewed-by: Matthew Brost Link: https://lore.kernel.org/r/20260327202749.222794-1-francois.dugast@intel.com Signed-off-by: Francois Dugast

drm/xe: Decouple GuC RC code from xe_guc_pc

2026-02-05T22:17:30+00:00

Move enable/disable GuC RC logic into the new file. This will allow us to independently enable/disable GuC RC and not rely on SLPC related functions. GuC already provides separate H2G interfaces to setup GuC RC and SLPC.
