Hi Rafael,
I run several popular Android performance benchmarks on teov7, using kernel 4.19.0 as my baseline because I happen to work on it. To backport teov7 to kernel 4.19.0, I also backport patch 5f26bdc: "cpuidle: menu: Fix wakeup statistics updates for polling state". The teov7 doesn't show regressions on such perf KPIs.
Compare "4.19 + 5f26bdc" and "4.19 + 5f26bdc + teov7" on Android with Intel Apollo Lake SoC:
Test Case Diff after appling teov7 Antutu_6 0.51% GFX5_openGL_Car_Chase 0.43% GFX5_openGL_Car_Chase_offscreen 0.25% GFX5_openGL_Manhattan31 0.75% GFX5_openGL_Manhattan31_1080_offscreen -0.10% Geekbench3.3 -0.13% H264_1080P_60FPS 0.00% H264_2160P_60FPS 0.00% H265_2K_10bit 0.00% H265_2K_8bit 0.00% Resume_time 1.31% full_boot -0.39%
Thanks Chen Hu
