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.

Chris Wilson (5):       drm/i915/gt: Program mocs:63 for cache eviction on gen9

That also needs commit 444fbf5d7058 ("drm/i915/gt: Declare gen9 has 64 mocs entries!") which seems to have not made it into this pull.

yeap, I'm sorry I have missed that one. dim doesn't deal very well with fixes for fixes and I end up missing that.

It is now on dif and will be part of this week's pull request.

Thanks for the heads up, Rodrigo.
