* gpu: nvgpu: Change GPCPLL NA rate in flightAlex Frid2015-03-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Added support for GM20b GPCPLL frequency change in NA mode outside of bypass. In this case the respective PLL DVFS detection settings are updated in flight. The implemented algorithm relies on characterization providing two frequency limits at the same voltage: max frequency on the F/V curve (Fmax@V) in NA mode with characterized DVFS coefficient, and safe frequency under the curve when DVFS coefficient is zero (Fsafe@V, which is effectively the same as Fmax@V in legacy/non-DVFS mode). Transition between two Fmax@V points on the curve includes: - Lowering frequency to Fsafe@V for the minimum V of the transition end-points - Setting DVFS coefficient to zero - Changing DVFS calibration point to the new voltage - Setting DVFS coefficient characterized for the new voltage - Setting final target frequency Note that voltage is changed by Tegra SoC DVFS before (when voltage increases), or after (whet voltage decreases) the above procedure. This commit kept NA mode disabled.

* gpu: nvgpu: implement poll() for semaphoresKonsta Holtta2015-03-18
| | | | | | | | | | | | | | | | | | Add poll interface and control ioctls for waiting for GPU job completion via semaphores. Poll on a gk20a channel file waits for events from pending semaphore interrupts (stalling) of that channel. New ioctls enable and disable the events, and clear a single interrupt event so that next poll doesn't wake up for it again.
