Bug Assessment : VLK - 4701
 
    • Reproduction rate : 100% (from CI Bug Log) from 6 runs.
    • Last seen 2 days back on TGL systems.
    • pm_rps@min-max-config-load – Subtest to verify the constraints with high load and to check if we can reach max.
    • pm_rps@waitboost – Subtest to verify if we can achieve boost using gem_wait.
    • pm_rps@reset – Subtest to test boost frequency after GPU reset.
    • In this case, the issue seems to be the min-max-config-loaded test that is failing in turn causing the waitboost and reset tests to fails. During the min-max test, the loaded-check expects the current frequency to be greater than the max frequency. The tests fails since this condition is not met. 
    • This condition should be verified. I will continue to follow the issue.

Thanks for the initial assessment. Once you know the user impact, can you please set the severity of this bug? Currently severity is not set.

GPU clocks on tgl are currently snafu; the HW does not seem to honour our frequency requests.
Comment 8 sujaritha.sundaresan 2019-11-04 22:42:30 UTC
Increasing the loaded wait timeout from 3000 to 3500 resolves this issue and allows the min-max-config-loaded, reset and waitboost tests to pass.
