Subject: PM QoS: Interface design question
Date: Tue, 22 Feb 2011 15:30:10 +0900 [thread overview]

Hi,
I am curious about an aspect of the design of PM QoS.
While working with the devices provided to configure PM QoS it struck me
that this is a rather unusual interface - holding a file descriptor to a
device open so long as configuration parameters apply. I understand that
this is a mechanism to apply parameters on a per-task basis. But I am
wondering if any consideration was given to using cgroups, which seem to me
to be designed specifically for applying QoS parameters on a per-task
basis.
