Subject: Question on intel_pstate driver
Date: Sat, 31 May 2014 15:44:02 -0600 [thread overview]
Message-ID: <1425705.adneRaQSNa@balsa> (raw)
Hi,
I've noticed a strange issue on my lenovo W530 laptop for a few months now.
Even with just a few percent cpu use, it spins the cpu up to it's full boost
on one or more cores, and tends to keep it there for an extended period. Ever
since my laptop has been significantly warmer, and louder than it was a while
back.
Cpu is a: i7-3720QM
Current kernel is: 3.14.4 (debian)
I've also tried vanilla kernels: 3.13, 3.14-rc8
Disabling the intel_pstep driver seems to disable boost states completely,
which is odd, as I could swear it worked before without it.
Is there something I can do to keep boost states while reducing the heat and
noise? It seems to be way over compensating for minimal amounts of cpu use.
