CPU frequency control fails for CPU 4 #14

Open qzed opened 2 years ago

qzed commented 2 years ago

CPU frequency control seems to fail for CPU 4 with the following log: 

[    1.984565] cpu cpu4: Voltage update failed freq=3072000
[    1.984571] cpu cpu4: failed to update OPP for freq=3072000
[    1.984576] cpu cpu4: Voltage update failed freq=3148800
[    1.984579] cpu cpu4: failed to update OPP for freq=3148800
[    1.984582] cpu cpu4: Voltage update failed freq=3148800
[    1.984585] cpu cpu4: failed to update OPP for freq=3148800

In addition to this, CPU core 0 seems to be pinned to ~80% usage (Note: these are likely separate issues, cpu4 is a big core whereas cpu0 is a little core).
