Merge tag 'drm-xe-next-2023-12-21-pr1-1' of https://gitlab.freedesktop.org/drm/xe/kernel into drm-next
Introduce a new DRM driver for Intel GPUs Xe, is a new driver for Intel GPUs that supports both integrated and discrete platforms. The experimental support starts with Tiger Lake. i915 will continue be the main production driver for the platforms up to Meteor Lake and Alchemist. Then the goal is to make this Intel Xe driver the primary driver for Lunar Lake and newer platforms. It uses most, if not all, of the key drm concepts, in special: TTM, drm-scheduler, drm-exec, drm-gpuvm/gpuva and others. Signed-off-by: Dave Airlie <airlied@redhat.com> [airlied: add an extra X86 check, fix a typo, fix drm_exec_init interface change].
