2014-09-19edp: sysedp : CPU/GPU priority depends on fGPUMatt Longnecker
Provide sysedp_dynamic_capping with the instantaneous GPU frequency when notifying it of the GPU load. 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.

2014-04-10EDP: add userspace knob to update ESR valueTimo Alho
This patch adds a sysfs entry /sys/power/sysedp/batmon/esr. This allows an user space process to update the current ESR value seen by the sysedp_batmon_calc component. sysedp_batmon_calc will compute the ratio between internal table based ESR estimate and value set from user space. This ratio will be then used to scale all future table based ESR estimations.

The calculation of AP+DRAM is now as follows: P_AP_DRAM = P_BAT - SUM(P_MAX) + min(SUM(P_MAX - P_THRESH), P_THROT) where P_AP_DRAM is power available for AP+DRAM P_BAT is total power available from battery SUM(P_MAX) is sum of maximum peak power of consumers (OC=1) SUM(P_THRESH) is sum of maximum peak power of consumers (OC=0) P_THROT is the maximum amount of power that HW thorttling can reduce.

2013-09-14EDP: tegra: rebase core client states on gainSivaram Nair
The core client E-states are scaled down proportional to the gain factor. This will reduce the difference between an available budget and AP+DRAM EDP table entries.

2013-09-14EDP: tegra: filter out isolated gpu peaksSivaram Nair
Isolated gpu load peaks degrade CPU performance without benefitting the GPU use case. This patch implements a filter to detect such events by requiring the GPU load to be above gpu_high_threshold for at least gpu_high_count (default is 2) number of consecutive notifications.

2013-09-14EDP: tegra: compensate for performance reductionsSivaram Nair
While calculating the CPU freq cap for a given AP+DRAM power budget (the allowed E-state level), performance is lost in two places. (1) after applying the gain factor: since the E-state level multiplied by the gain factor does not exactly match a row in the AP+DRAM table (resulting in the selection of a lower value). (2) while looking up in the cpu power limit table: some delta mW is lost as in the above case (since there is no exact match, we are choosing a lower level) (1) is fixed by adding the delta amount to cpu power (2) is fixed by choosing a ceiling value (this is OK since in almost all cases, we have some battery cap remaining).

T148 AP+DRAM EDP tables require GPU and EMC freqs to be specified in kHz. Pluto and Macallan already specifies the freqs in mHz - so this patch contains board file changes too (since these have to go as a single change).
