Hi Josh,
|
||||
|
||||
Sorry for the slow resopnse you caught me on vacation :-)
|
||||
|
||||
I do not have either of these VMs ATM to test against. The patch below
|
||||
should solve the problem though It looks like the VM is returning zero
|
||||
for the highest P state (frequency) MSR. The patch will have the driver refuse
|
||||
to load and the system should fall through to one of the other configured
|
||||
governors/ scaling drivers.
|
||||
|
||||
Is it possible for tyou to test the patch below while I try to get a test setup
|
||||
put together locally?
|
||||
|
||||
Thanks in advance
|
||||
--Dirk

cpufreq/intel_pstate: Do not load on VM that do not report max P state.
|
||||
|
||||
It seems some VMs support the P state MSRs but return zeros. Fail
|
||||
gracefully if we are running in this environment.
