wltests (workload tests)

ARM is pleased to announce a new automated test suite for benchmarking Linux scheduler & EAS improvements on Android workloads.

wltests is built on top of Lisa and Workload Automation (in-development version of WA v3) with the goal of: * automatically running a range of Android-based tests on a platform, collecting performance and power metrics * comparing different kernel versions and/or kernel options * analyzing differences using Lisa-based notebooks * easier porting to custom platform

It is intended to allow full evaluation of EAS/scheduler changes with real Android workloads (for example PELT vs. WALT comparisons)

The current set of workloads are: * Jankbench * Exoplayer for video & audio playback tests * Youtube (if gapps available on platform) * PCmark * Geekbench * Homescreen (to measure steady state energy consumption)

Install entire Lisa first according to installation instructions (Lisa now includes an in-development version of WA v3) https://github.com/ARM-software/lisa/wiki/Installation#required-dependencies The VM can be used if you have incompatibilities with locally-installed python libraries

Please see README.md in the wltests directory: https://github.com/ARM-software/lisa/tree/master/tools/wltests

If you have concerns about results being published for in-development hardware, comment out the commercial benchmarks (PCmark & Geekbench) in the agenda: tools/wltests/agendas/sched-evaluation-full.yaml

Platform - currently only one public platform (Linaro HiKey960): tools/wltests/platforms/hikey960_android-4.4 (this actually works for 4.4 and 4.9 based kernels)

Adding a new platform is easy - 3 files in platform directory

Any questions please let us know!
