Hi Dave and Daniel,
Please ignore the pull request I had sent yesterday and use only this one.
I had missed one patch: 14d1eaf08845 ("drm/i915/gt: Protect context lifetime with RCU").
Also, please notice that the commit 6db58901c2aa ("drm/i915/display: return earlier from
+intel_modeset_init() without display") was not actually a crucial fix, but it
+allowed a clean pick of the use-after-free one.
Here goes drm-intel-fixes-2020-12-03:
Fixes for GPU hang, null dereference, suspend-resume, power consumption, and use-after-free.
- Program mocs:63 for cache eviction on gen9 (Chris)
- Protect context lifetime with RCU (Chris)
- Split the breadcrumb spinlock between global and contexts (Chris)
- Retain default context state across shrinking (Venkata)
- Limit frequency drop to RPe on parking (Chris)
- Return earlier from intel_modeset_init() without display (Jani)
- Defer initial modeset until after GGTT is initialized (Chris)
Thanks,
Rodrigo.
