[PATCH 0/4] some optimization for evergreen cs

[Grazvydas Ignotas]

These patches try to reduce CPU usage of register command checker
without affecting functionality.
For me this gives 3-4% perf improvement in glxgears and ~1% CPU usage reduction
in "The Talos Principle" CS thread.

Grazvydas Ignotas (4):
  drm/radeon: simplify register checker
  drm/radeon: split evergreen_cs_check_reg
  drm/radeon: refactor register check loop
  drm/radeon: remove use of volatile qualifier
