Hi Dave & Daniel,
Here goes the first drm-intel-gt-next PR towards 6.1. Quite a small one.
As primary things, there's the parallel support of GuC v69 and v70
which already went in via -fixes, improvements to the TLB invalidation
performance regressions, further DG2 enabling and improved debugging
for GuC errors.
On top of that, locking simplification for freeing objects to avoid
potential system freeze, addition of gt/gtN/.defaults (including freq
to start), silencing some messages that are not errors.
Regards, Joonas
PS. I left a few commits out from top of drm-intel-gt-next as there is fixup
needed for at least one. I will include those in the next PR.

drm-intel-gt-next-2022-08-24:
UAPI Changes:
- Create gt/gtN/.defaults/ for per gt sysfs defaults
Create a gt/gtN/.defaults/ directory (similar to
engine/<engine-name>/.defaults/) to expose default parameter values for
each gt in sysfs. This allows userspace to restore default parameter values
after they have changed.
Driver Changes:
- Support GuC v69 in parallel to v70 (Daniele)
- Improve TLB invalidation to limit performance regression (Chris, Mauro)
- Expose per-gt RPS defaults in sysfs (Ashutosh)
- Suppress OOM warning for shmemfs object allocation failure (Chris, Nirmoy)
- Disable PCI resize on 32-bit machines (Nirmoy)
- Update DG2 to GuC v70.4.1 (John)
- Fix CCS data copying on DG2 during swapping (Matt A)
- Add DG2 performance tuning setting recommended by spec (Matt R)
- Add GuC <-> kernel time stamp translation information to error logs (John)
- Record GuC CTB info in error logs (John)
- Route semaphores to GuC for Gen12+ when enabled (Michal Wi, John)
- Improve resilency to bug #3575: Handle reset timeouts under unrelated kernel hangs (Chris, Ashutosh)
- Avoid system freeze by removing shared locking on freeing objects (Chris, Nirmoy)
- Demote GuC error "No response for request" into debug when expected (Zhanjun)
- Fix GuC capture size warning and bump the size (John)
- Use streaming loads to speed up dumping the GuC log (Chris, John)
- Don't abort on CTB_UNUSED status from GuC (John)
- Don't send spurious policy update for GuC child contexts (Daniele)
- Don't leak the CCS state (Matt A)
- Prefer drm_err over pr_err (John)
- Eliminate unused calc_ctrl_surf_instr_size (Matt A)
- Add dedicated function for non-ctx register tuning settings (Matt R)
- Style and typo fixes, documentation improvements (Jason Wang, Mauro)
- Selftest improvements (Matt B, Rahul, John)
