[PATCH v10 0/2] Refactor Gen11+ SAGV support

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



For Gen11+ platforms BSpec suggests disabling specific
QGV points separately, depending on bandwidth limitations
and current display configuration. Thus it required adding
a new PCode request for disabling QGV points and some
refactoring of already existing SAGV code.
Also had to refactor intel_can_enable_sagv function,
as current seems to be outdated and using skl specific
workarounds, also not following BSpec for Gen11+.

Stanislav Lisovskiy (2):
  drm/i915: Refactor intel_can_enable_sagv
  drm/i915: Restrict qgv points which don't have enough bandwidth.
