This patch set touches Xe and i915 drivers. On i915 is checked if running on Xe2 hardware and enable framebuffer ccs decompression unconditionally for tile4 framebuffers. On Xe driver with Xe2 hardware check if ccs compression is in use and behave accordingly; attempt to use ccs with linear and x-tiled framebuffers will result in -EINVAL as display does support decompression only on tile4. v2: Add compressed flag into pat index table and use that. Try to avoid situation where framebuffer can be bound with different pat index after it was pinned. v3: Small changes. Changed pat index annotation code author for Matthew as it was cut'n'paste from review comment. v4: Drop attempts to control ccs for linear/x-tile. Just unconditionally enable tile4 decompression on display.
