I am trying to reproduce the issue but so far not successful. I did move to power-domains for CPUFreq on Juno. IIUC all we need is both cpufreq and performance genpd drivers in the kernel and then GPU using perf genpd fails with probe deferral right ? I need pointers to reproduce the issue so that I can check if what I have cooked up as a solution really works. -- Regards, Sudeep
