When the frequency seems stuck at 800 MHz, then please put a load on a CPU and look at the pstate request and granted MSR's.
Example, where I force CPU 2: $ taskset -c 2 yes > /dev/null and then look at the request and granted pstates: $ sudo rdmsr --bitfield 15:8 -u -a 0x199 8 8 48 8 30 8 8 8 8 33 8 8 and $ sudo rdmsr --bitfield 15:8 -u -a 0x198 48 48 48 48 48 48 48 48 48 48 48 48 So, and as expected, I am asking for the highest patete possible for CPU 2 and being given pstate 48 on all CPUs. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1945221 Title: CPU frequency stuck at minimum value..again Ubuntu 20.04.3 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/thermald/+bug/1945221/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
