Subject: [RFC INCOMPLETE] tick based timekeeping from a housekeeping CPU
Date: Wed, 24 Jun 2015 10:57:49 -0400 [thread overview]
Message-ID: <1435157880-22925-1-git-send-email-riel@redhat.com> (raw)
This series seems to make basic tick based time sampling from a
housekeeping CPU work, allowing us to have tick based accounting
on a nohz_full CPU, and no longer doing vtime accounting on those
CPUs.
It still needs a major cleanup, and steal time accounting and irq
accounting are still missing.
Just posting this to get a sense of whether I am headed in the right
direction, or whether we need some major overhaul/cleanup of part of
the code first.
