# freq_sampler.sh <outfile> [period_s=2] - DEVICE-SIDE (pushed to /data/local/tmp, run as root in the
|
|
# background for the length of one measurement, killed by the caller). One line per sample:

|
# t=<uptime> c<policy>=<cur>/<max> ... gpu=<devfreq cur> gpuclk=<kgsl gpuclk> tpl=<thermal_pwrlevel>
|
|
# thr=<throttling> busy=<gpu_busy_percentage> cpuT=<hottest cpu zone> gpuT=<hottest gpuss zone> skinT=<skin>
|
|
# Cheap sysfs reads only, so the run it watches is not perturbed. freqcheck.py turns the file into
|
|
# min/max/peak and a VALID/INVALID verdict (P15 measurement-validity rule).
