Hi,

There is not known root cause to why we end up in a situation
where the dmc doesn't anymore obey us on dc state setup.

https://bugs.freedesktop.org/show_bug.cgi?id=93698
https://bugs.freedesktop.org/show_bug.cgi?id=93697

But here are few patches to alleviate the consequences
if that happens. We really want to keep the gpu alive
even if the dmc starts hallucinating.

Mika Kuoppala (2):
  drm/i915: Stop using DC states if firmware disagrees on the state
  drm/i915: Use init power domain during reset
