[PULL] drm-xe-next-fixes

[Rodrigo Vivi]

Hi Dave and Sima,

 Here goes a very early drm-xe-next-fixes with 2 important fixes
 that are going to impact user space.

 1. The first one is the rename of the OA stuff from the bad 'perf'
 name to the xe_observation. Although the rename in the uapi
 header is likely inoffensive because our UMDs always copy the
 header to their code, there's a sysfs filename change that is
 impacting mesa.

 For this one Mesa MR is ready and they are only waiting for this
 pull request to be picked by you so they can merge that to Mesa:
 https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/30027

 With both sides in place, there won't be any kernel version
 released with the bad naming and no Mesa released using that
 filename. This is the main reason that I'm sending this PR
 earlier than normal.

 2. The second case, which also impact user space is the
 write-back caching mode for system memory on DGFX. In this case
 we introduce a limitation in the cache selection uapi that is
 transparent to UMDs. I mean, no change on their side is needed.
 Coherence is maintained with some know possible visible and
 acceptable/accepted differences in CPU access speed.

 Thanks,
 Rodrigo.
