Hi,
I have applied the whole series to the linux-next branch of the linux-pm.git
Thanks!
tree, but I'm quite unsure about [7/8]. Is it really necessary? I mean, since
we want users to switch to a different driver anyway, which already has a knob
providing the functionality in question, what's the point really?
Afaik this was mostly for compiler people or other developers doing
benchmarks to be able to avoid fluctating numbers caused by turbo/boost
mode.
I don't know whether it's used by any userspace tool.
Well, at least we use it here in quite some scripts, both for testing
and for benchmarking.
As this has been in for 2.5 year by now, I'd like to keep it for one or
two more major releases and then remove it.
If, it would certainly
be an AMD specific tool for developers. If you (AMD) know a userspace tool
out there it may make sense to keep it the one or other kernel round,
otherwise I guess it can simply be deleted.
I will add the functionality (to enable/disable turbo/boost mode)
to cpupower userspace tool as soon as this is in.
Shouldn't be much more than a -t option and a
one liner to read out or set another cpufreq sysfs file.
Thanks, that would be nice.
Regards,
Andre.
