| |
This is more of a place holder for a problem discussed here:
http://lkml.org/lkml/2005/5/7/98
I am sending out this patch as a record of the load balance problem that exists with NO_IDLE_HZ implementations.
Ingo had mentioned at OLS that it would be nice for any non-idle-cpu-waking-up-sleeping-cpu.patch to maintain the load balancing algorithms intact. Basically the algorithm is offloaded from a idle cpu to non-idle CPU and potentially lets the idle CPU sleep for longer periods.
I have some ideas to guarantee that load balance algorithms are not changed and yet let idle CPUs sleep as long as they want. But I have been unable to implement them because of other pressing (read dyn-tick!) work. Plan to work on such a patch and send out for discussions (& flames :) as soon as possible.
