big.LITTLE IKS benchmark testing taking too long time than before

[Naresh Kamboju]

we have workbench invocation for TC2 which previously took approximately 4 minutes to complete when the logs were getting printed. But now without logs it takes 45 minutes to execute.

single loop log;

Its difficult to comment currently since the stdout logs are missing in the logs. Can you test it once with lava-android-test locally on your board and let us know if it is a problem with lava-android-test integration and takes 40 minutes ?

Found the issue. Looks like the workbench patches for LAVA branch were wrongly rebased. Looking at the configs which are split it appears that each congig has NumTimes set as 15 which is supposed to be configured as 1:

ID,Status,NumTimes,UseCase,OS Mode,A7 Cores,A15 Cores,A7 Governor,A15 Governor,hispeed_freq,above_hispeed_delay,go_hispeed_load,timer_rate
  2a,yes,15,Bbench_with_audio,iks_cpu,2,2,Interactive,Interactive,500000,80000,85,20000
