[LTP] [PATCH 2/2] power_management: Remove runpwtests0[125].sh

Petr Vorel
2026-03-18T13:27:23Z

These tests use power-aware scheduling sysfs, which were removed in
8e7fbcbc22c12 ("sched: Remove stale power aware scheduling remnants and dysfunctional knobs")
in kernel 3.5:

/sys/devices/system/cpu/sched_mc_power_savings
/sys/devices/system/cpu/sched_smt_power_savings

runpwtests05.sh was disabled since 2015 anyway.
Remove also pm_sched_domain.py and pm_get_sched_values.c (used only by
runpwtests05.sh) and .gitignore (contained only removed
pm_get_sched_values).
