[Intel-gfx] [PATCH] drm/i915: Ajdust down threshold in intel_pm.

2012-07-03 Thread Stéphane Marchesin
The up and down thresholds are very asymetric, so it is possible to have a case where a spike of rendering increases the GPU clock to the max (because the up threshold is low) and then a simple blinking cursor is enough to keep the clock at the maximum speed forever (because the down threshold is h
