Re: [PATCH 2/5] acpi-cpufreq: Add support for disabling dynamic overclocking

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



While this patch will work and is not invalid, I don't like it.

It advertises a user I/F that suggests that disabling turbo
is on a per logical processor basis -- but a write to
any of the attributes will write to every CPU in the system.

Either it should do per-cpu limiting (which, btw doesn't
work if you use the MISC_ENABLES MSR method in this patch,
and would instead need to use the PERF_CTL.32 method)
or there should be a per-system attribute
that reflects that this knob is per-system.

thanks,
