Thanks for the timely reply, Daniel. The intention to bring debugfs for RPS boost and idle is when boost and idle are disabled, we are able to have a clear vision of what normal turbo algorithm. It‘s very helpful to verify if the turbo algorithm is working as expected, at least from the VPG va

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

2014-04-25 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
