-----Original Message----- From: Lisovskiy, Stanislav stanislav.lisovskiy@intel.com Sent: Thursday, December 9, 2021 5:47 AM To: intel-gfx@lists.freedesktop.org Cc: dri-devel@lists.freedesktop.org; Lisovskiy, Stanislav stanislav.lisovskiy@intel.com; Saarinen, Jani jani.saarinen@intel.com; C, Ramalingam ramalingam.c@intel.com; ville.syrjala@linux.intel.com; Deak, Imre imre.deak@intel.com; Chery, Nanley G nanley.g.chery@intel.com Subject: [PATCH 2/2] drm/i915/dg2: Tile 4 plane format support
Tile4 in bspec format is 4K tile organized into 64B subtiles with same basic shape as for legacy TileY which will be supported by Display13.
v2: - Moved Tile4 assocating struct for modifier/display to the beginning(Imre Deak) - Removed unneeded case I915_FORMAT_MOD_4_TILED modifier checks(Imre Deak) - Fixed I915_FORMAT_MOD_4_TILED to be 9 instead of 12 (Imre Deak)
v3: - Rebased patch on top of new changes related to plane_caps. - Added static assert to check that PLANE_CTL_TILING_YF matches PLANE_CTL_TILING_4(Nanley Chery) - Fixed naming and layout description for Tile 4 in drm uapi header(Nanley Chery)
v4: - Extracted drm_fourcc changes to separate patch(Nanley Chery)
Oh, when we discussed this I didn't realize until later that you were asking for feedback on whether or not the fourcc changes needed to be split out. I think either way (combined or separate) is fine. Sorry for the confusion.
