# bench_session.sh start|stop|status - P15 measurement-validity rule, device side (Lenovo Y700, SM8650).
|
|
#
|
|
# start:
|
|
# 1. records each frequency-moving service's prior state and the msm_performance requests
|
|
# (/data/local/tmp/p15-bench-session, also echoed to the caller's log);
|
|
# 2. stops those services: thermal-engine, the QTI perf HAL, the vendor perf service, Lenovo's
|
|
# performance and hyperschedule services. Their requests OUTLIVE them: the perf stack's
|
|
# game-mode levels land in /sys/kernel/msm_performance/parameters/cpu_{max,min}_freq, a
|
|
# frequency QoS that clamps scaling_max_freq below any pin (measured 2026-10-08: 787 / 1286 /
|
|
# 1075 / 1248 MHz on policies 0/2/5/7 while pin_clocks.sh believed it had pinned 2035 MHz);
|
|
# 3. releases those requests and re-pins (pin_clocks.sh);
|
|
# 4. force-stops the anland desktop app, recording whether it ran. Its activity takes the
|
|
# foreground back whenever it is paused, so FCL launched over it never reaches the world
|
|
# (2026-10-08: a job's own end-of-run relaunch left it up and the next job got 0 of 4 worlds).
|
|
# stop: unpins the clocks (pin_clocks.sh restore: scaling min/max and the GPU devfreq window go back to
|
|
# their saved pre-pin values; before 2026-10-09 stop left them pinned), then starts every service
|
|
# that was running before start, and verifies each is running again;
|
|
# relaunches the anland app if it ran before start (keeps anland usable).
|
|
# ALWAYS run it - callers trap it on EXIT/INT/TERM, so an interrupted session restores too.
|
|
# Kernel-level protection (LMh, BCL, kernel thermal trip points) is never touched; the run's sampler
|
|
# (freq_sampler.sh -> freqcheck.py) shows any frequency collapse, and a collapse ends benchmarking.
