Message

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.

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