[PATCH 0/2] drm/i915/dg2: Test DC5

[Imre Deak]

Hi,

yes, this could be related to enabling DC5.

However the MMIO BAR lost issue is not seen now, and the hang in
i915_selftest at live seems to be unrelated to the change disabling flip
queue handlers:

https://intel-gfx-ci.01.org/tree/drm-tip/Patchwork_103888v3/bat-dg2-9/igt@i915_selftest@live@perf.html

So I think
drm/i915/d12+: Disable DMC firmware flip queue handlers
should be merged and i915_selftest issue resolved before enabling DC5.
