[PULL] drm-intel-gt-next

[Joonas Lahtinen <joonas.lahtinen@linux.intel.com>]

Hi Dave & Sima,

A rather late first drm-intel-gt-next PR towards v6.8.

As most significant change we have addition of the DRM fdinfo memory stats
functionality. Then DG2 and MTL workaround additions and fixes and a few
for older platforms as well. PMU WARN_ON splat cleanup.

The rest is mostly code cleanups and fixes for odd corner cases.

Best Regards, Joonas

UAPI Changes:

-   drm/i915: Implement fdinfo memory stats printing

    Use the newly added drm_print_memory_stats helper to show memory
    utilisation of our objects in drm/driver specific fdinfo output.

    To collect the stats we walk the per memory regions object lists
    and accumulate object size into the respective drm_memory_stats
    categories.

Cross-subsystem Changes:

- Backmerge of drm-next (to bring drm-intel-next for PXP changes)

Driver Changes:

- Wa_18028616096 now applies to all DG2 (Matt R)
- Drop Wa_22014600077 on all DG2 (Matt R)
- Add new ATS-M device ID (Haridhar)
- More Meteorlake (MTL) workarounds (Matt R, Dnyaneshwar, Jonathan,
  Gustavo, Radhakrishna)
- PMU WARN_ON cleanup on driver unbind (Umesh)
- Limit GGTT WC flushing workaround to pre BXT/ICL platforms
- Complement implementation for Wa_16018031267 / Wa_16018063123
  (Andrzej, Jonathan, Nirmoy, Chris)

- Properly print internal GSC engine in trace logs (Tvrtko)
- Track gt pm wakerefs (Andrzej)
- Fix null deref bugs on perf code when perf is disabled (Harshit,
  Tvrtko)
- Fix __i915_request_create memory leak on driver unbind (Andrzej)
- Remove spurious unsupported HuC message on MTL (Daniele)
- Read a shadowed mmio register for ggtt flush (Vinay)
- Add missing new-line to GT_TRACE (Andrzej)
- Add drm_dbgs for critical PXP events (Alan)
- Skip pxp init if gt is wedged (Zhanjun)

- Replace custom intel runtime_pm tracker with ref_tracker library
  (Andrzej)
- Compiler warning/static checker/coding style cleanups (Arnd, Nirmoy,
  Soumya, Gilbert, Dorcas, Kunwu, Sam, Tvrtko)
- Code structure and helper cleanups (Jani, Tvrtko, Andi)
- Selftest improvements (John, Tvrtko, Andrzej)
