linux.git/drivers/gpu/drm/xe/display/xe_frontbuffer.h, branch master Linux kernel source tree drm/{i915, xe}/frontbuffer: move frontbuffer handling to parent interface 2026-03-11T09:32:10+00:00 Jani Nikula jani.nikula@intel.com 2026-03-02T18:17:37+00:00 2cca25160d159e6351e3273b088db0b4f359ef6a Move the get/put/ref/flush_for_display calls to the display parent interface. For i915, move the hooks next to the other i915 core frontbuffer code in i915_gem_object_frontbuffer.c. For xe, add new file xe_frontbuffer.c for the same. Note: The intel_frontbuffer_flush() calls from i915_gem_object_frontbuffer.c will partially route back to i915 core via the parent interface. This is less than stellar.

Move the get/put/ref/flush_for_display calls to the display parent
interface.

For i915, move the hooks next to the other i915 core frontbuffer code in
i915_gem_object_frontbuffer.c. For xe, add new file xe_frontbuffer.c for
the same.

Note: The intel_frontbuffer_flush() calls from
i915_gem_object_frontbuffer.c will partially route back to i915 core via
the parent interface. This is less than stellar.
