Does the "NO_HZ" option not work on x86_64?
Yes, It's currently not supported on x86_64. Even on i386 it does have some problems AFAIK.
Thanks....I've been using it on ia32 on 3 different hardware setups and no problems -- but none of them are laptops, and none of them have CPU Frequency scaling (which I vaguely remember reading about a problem with variable cpu frequencies and the 'on-demand' scheduling algorithm. I was surprised when I switched the one 'Core Duo'-based computer to an x86_64 based kernel and had the int count in the stock suse kernel jump by more than 1000% (10x). Perhaps I'm naive, but since it is the exact same hardware, it doesn't seem like it should be *too* difficult to get working. But hey...the way things are done in kernel land, one never knows... :-) -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
