This is a new data provider to get state residency from fvp_stats, which is similar with DVFS data provider. But the difference is that CPU frequency table is read from cpufreq sysfs and not predefined in the config. Bug: 272642210 Bug: 267638537 Test: dumpsys android.hardware.power.stats.IPowerStats/default Change-Id: I22451b55dee5dfb0a1b36497533c2063984d5483 Signed-off-by: Darren Hsu <darrenhsu@google.com>
