[Intel-gfx] [PATCH] drm/i915: Reduce frequency of unspecific HSW reg debugging

2015-08-26 Thread Chris Wilson
Delay the expensive read on the FPGA_DBG register from once per mmio to once per forcewake section when we are doing the general wellbeing check rather than the targetted error detection. This almost reduces the overhead of the debug facility (for example when submitting execlists) to zero whilst k
