[Bug 524281] Re: Tens of wakes per second in "[kernel scheduler] Load balancing tick" on Core 2 Duo even with only 1 core enabled

 

Based on devsk's comment, I've uploaded two kernels for lucid to my power-saving PPA:
https://launchpad.net/~brian-rogers/+archive/power

The first, 2.6.35-0unpatched+18.24~lucid, is essentially just maverick's
2.6.35-18.24 built for lucid. Note that despite the name 'unpatched', it
still has the patch for this bug because that has been included in
maverick's standard kernel.

The second kernel, 2.6.35-power+18.24~lucid, should be identical except
that CONFIG_LATENCYTOP, CONFIG_SCHED_DEBUG, and CONFIG_SCHEDSTATS have
been removed from the configuration.

Does anyone else observe the same thing as devsk, that on a kernel with
the latencytop and scheduler statistics options disabled, wakes per
second are lower? Or do they remain the same?

(BTW, I also uploaded a 'power' kernel for maverick, which can be
compared against 2.6.35-18.24.)
