[Intel-gfx] [PATCH] drm/i915: vlv: fix RPS interrupt mask setting

2014-04-03 Thread Imre Deak
This typo may lead to missed RPS interrupts and as a result a too low or too high frequency for the current workload. The interrupt mask will be set properly at a subsequent GPU idle event, but can get corrupted again at the next RPS up/down event. Signed-off-by: Imre Deak --- drivers/gpu/drm/i9
