We have couple of customer issues, related to SAGV/QGV point
calculation. Those patches contain fixes plus some additional
debugs for those issues.

Stanislav Lisovskiy (3):
  drm/i915: Add meaningful traces for QGV point info error handling
  drm/i915: Extract code required to calculate max qgv/psf gv point
  drm/i915: Disable SAGV on bw init, to force QGV point recalculation
