[Intel-gfx] [PATCH v2 0/8] drm/i915: SAGV block time fixes

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala at linux.intel.com>

Try to fix SAGV block time handling:
- zero means no SAGV
- avoid integer overflows
- slightly better debug logs
- assorted cleanups

v2: reorder to allow stable backport of the zero->no SAGV patch
    Fix/clean some PSF GV stuff as well that caught my eye

Ville Syrjälä (8):
  drm/i915: Treat SAGV block time 0 as SAGV disabled
  drm/i915: Rework SAGV block time probing
  drm/i915: Probe whether SAGV works on pre-icl
  drm/i915: Reject excessive SAGV block time
  drm/i915: Rename pre-icl SAGV enable/disable functions
  drm/i915: Fix PSF GV point mask when SAGV is not possible
  drm/i915: Unconfuses QGV vs. PSF point masks
  drm/i915: Rename QGV request/response bits
