The first three patches in this series are taken from
https://patchwork.freedesktop.org/series/116868/
These patches are included here because the last patch
has dependency on the pat_index refactor.
This series is focusing on uAPI changes,
1. end support for set caching ioctl [PATCH 4/5]
2. add set_pat extension for gem_create [PATCH 5/5]
v2: drop one patch that was merged separately
341ad0e8e254 drm/i915/mtl: Add PTE encode function
v3: rebase on https://patchwork.freedesktop.org/series/117082/
Hi, Fei.
Does this uAPI update also affect any discrete GPUs supported by i915,
And in that case, does it allow setting non-snooping PAT indices on
those devices?
If so, since the uAPI for discrete GPU devices doesn't allow incoherency
between GPU and CPU (apart from write-combining buffering), the correct
CPU caching mode matching the PAT index needs to be selected for the
buffer object in i915_ttm_select_tt_caching().
Thanks,
Thomas

drm/i915: use pat_index instead of cache_level
drm/i915: make sure correct pte encode is used
drm/i915/mtl: end support for set caching ioctl
drm/i915: Allow user to set cache at BO creation
