Adds a new intel backend for interfacing with the Xe kernel driver.
Currently only tested on gen12 (Xe1; e.g. TGL, ADL, MTL).
Test 1: drm-tests (natively): stop ui and then run:
- mapped_texture_test
- null_platform_test -m [I915_FORMAT_MOD_X_TILED|I915_FORMAT_MOD_Y_TILED]
- plane_test (by default it uses NV12)
Test 2: full OS: boot to UI, execute webGL and/or YouTube successfully and watch
the terminal: TERM=xterm watch -n1 -d cat /sys/kernel/debug/dri/0/i915_display_info
for color formats and display plane usage
v1: Carlos Santa <carlos.santa@intel.corp-partner.google.com>
v2: Ryan Neph <ryanneph@google.com>
- formatting fixes
- remove deprecated #ifdef I915_SCANOUT_Y_TILED conditional compilation
- add missing backend_xe implementations
- mimic i915_add_combinations
- Match formatting, order of operations, and add the missing combo for
YVU420_ANDROID + USE_CAMERA_WRITE.
- In a future CL, we'll factor this into a common function called by both
backends.
- simplify xe_bo_map()
- The conditional body is always taken, so remove the conditional entirely.
- mark late-gen12 as mtl_or_newer until proper version handling is used.
