* 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.

Transitions that may create glitch are implemented in glitch-less steps with minimum possible interim divider value (for example, 1 <=> 2 transition has interim value 3: 1 <=> 3 <=> 2). Steps allowed for glitch-less transitions may not always have frequency jump at/below VCO min/2 (in the example above 1st step jumps 2/3 of VCOmin). Enabled external linear divider at 1:2 during such steps. Used extra write of the same data when changing GM20b linear divider.

Modify the gpu/cpu priority decision logic to choose CPU priority until GPU frequency gets "near" the CPU-priority-limited-GPU-fmax. Introduce the priority_bias debugfs parameter to facilitate tuning of "near". priority_bias takes a value from 0 to 100.
