Hi Dave & Daniel,

Here comes the final feature PR for 5.16.

As the biggest thing it adds multi-LRC (parallel) submission
implementation for GuC and a simplified parallel submission uAPI
to go with that (only works with GuC for now). It is has a similar
mission to the bonded submission uAPI, take a look at the kerneldocs
for full detail.

Then there are some improvements to making sure old pages are flushed from
caches before making them available to userspaces. Those extra flushes may
be visible in corner case scenarios if application is frequently importing
new dmabufs on non-LLC hardware. The better approach would anyway be to
recycle a pool of dmabufs than destroy and recreate.

In addition to that, it's only minor changes with mainly developer
impact and those can be seen in shortlog.

Regards, Joonas

PS. There has been request to backmerge drm-next after you merge this
    PR, to bring in dma-resv iterators. I'll do that.

PPS. Will send out the dim patches for the "for-linux-next-gt" branch
     updating to make sure we avoid the future conflicts.

UAPI Changes:

- Expose multi-LRC submission interface

  Similar to the bonded submission interface but simplified.
  Comes with GuC only implementation for now. See kerneldoc
  for more details.

  Userspace changes: https://github.com/intel/media-driver/pull/1252

- Expose logical engine instance to user

  Needed by the multi-LRC submission interface for GuC

  Userspace changes: https://github.com/intel/media-driver/pull/1252

Driver Changes:

- Fix blank screen booting crashes when CONFIG_CC_OPTIMIZE_FOR_SIZE=y (Hugh)
- Add support for multi-LRC submission in the GuC backend (Matt B)
- Add extra cache flushing before making pages userspace visible (Matt A, Thomas)
- Mark internal GPU object pages dirty so they will be flushed properly (Matt A)

- Move remaining debugfs interfaces i915_wedged/i915_forcewake_user into gt (Andi)
- Replace the unconditional clflushes with drm_clflush_virt_range() (Ville)
- Remove IS_ACTIVE macro completely (Lucas)
- Improve kerneldocs for cache_dirty (Matt A)

- Add missing includes (Lucas)
- Selftest improvements (Matt R, Ran, Matt A)
