drm/xe/fbdev: use the same 64-byte stride alignment as i915

2025-12-18T13:03:39+00:00

[ Upstream commit 4a36b339a14ae6f2a366125e3d64f0c165193293 ] For reasons unknown, xe uses XE_PAGE_SIZE alignment for stride. Presumably it's just a confusion between stride alignment and bo allocation size alignment. Switch to 64 byte alignment to, uh, align with i915. This will also be helpful in deduplicating and unifying the xe and i915 framebuffer allocation.

drm/xe: Convert xe_bo_create_pin_map() for exhaustive eviction

2025-09-10T07:16:06+00:00

Introduce an xe_bo_create_pin_map_novm() function that does not take the drm_exec paramenter to simplify the conversion of many callsites. For the rest, ensure that the same drm_exec context that was used for locking the vm is passed down to validation. Use xe_validation_guard() where appropriate. v2: - Avoid gotos from within xe_validation_guard(). (Matt Brost) - Break out the change to pf_provision_vf_lmem8 to a separate patch. - Adapt to signature change of xe_validation_guard().

drm/xe: Convert xe_bo_create_pin_map_at() for exhaustive eviction

2025-09-10T07:16:05+00:00

Most users of xe_bo_create_pin_map_at() and xe_bo_create_pin_map_at_aligned() are not using the vm parameter, and that simplifies conversion. Introduce an xe_bo_create_pin_map_at_novm() function and make the _aligned() version static. Use xe_validation_guard() for conversion. v2: - Adapt to signature change of xe_validation_guard().
