From: Mike Chan on 20 May 2010 14:50 v2: Rebased off of Thomas Renninger's patch for cgroups_cpuacct refactoring, which is based off of linus's tree. Thomas it might be easier to merge our patches if you take these patches and put them in a series ontop of your original patches (presuming there are no objections to your patch). This patch series introduces cpu frequency and power tracking for cpuacct cgroups. A similar patch set was discussed a while back and it was concluded that due to varying architectures (ppc, x86 with overboot) you cannot account for frequencies and their power consumption generically in sched.c, thus we have platform specific hooks the cpuacct can call into (if available). This patch series is not 3 instead of 4. I have left out the power implementation for OMAP due to implementation conflicts in linux-next.
