[Intel-gfx] [PATCH v2] drm/i915: Debugfs disable RPS boost and idle

2014-04-28 Thread Daisy Sun
RP frequency request is affected by 2 modules: normal turbo algorithm and RPS boost algorithm. By adding RPS boost algorithm to the mix, the final frequency becomes relatively unpredictable. Add a switch to enable/disable RPS boost functionality. When disabled, RP frequency will follow the normal t
