[Intel-gfx] [PATCH v3 01/11] drm/i915: Add a table with a descriptor for all i915 modifiers
Imre Deak
imre.deak at intel.com
Thu Oct 14 22:09:11 UTC 2021
Add a table describing all the framebuffer modifiers used by i915 at one
place. This has the benefit of deduplicating the listing of supported
modifiers for each platform and checking the support of these modifiers
on a given plane. This also simplifies in a similar way getting some
attribute for a modifier, for instance checking if the modifier is a
CCS modifier type.
While at it drop the cursor plane filtering from skl_plane_has_rc_ccs(),
as the cursor plane is registered with DRM core elsewhere.
v1: Unchanged.
v2:
- Keep the plane caps calculation in the plane code and pass an enum
with these caps to intel_fb_get_modifiers(). (Ville)
- Get the modifiers calling intel_fb_get_modifiers() in i9xx_plane.c as
well.
v3:
- s/.id/.modifier/ (Ville)
- Keep modifier_desc vs. plane_cap filter conditions consistent. (Ville)
- Drop redundant cursor plane check from skl_plane_has_rc_ccs(). (Ville)
- Use from, until display version fields in modifier_desc instead of a mask. (Jani)
- Unexport struct intel_modifier_desc, separate its decl and init. (Jani)
- Remove enum pipe, plane_id forward decls from intel_fb.h, which are
not needed after v2.
