This is the dynamic ticks patch for i386 as written by Tony Lindgen <[email protected]> and Tuukka Tikkanen <[email protected]>. Patch for 2.6.13-rc5

There were a couple of things that I wanted to change so here is an updated version. This code should have stabilised enough for general testing now.

The sysfs interface was moved to its own directory in /sys/devices/system/dyn_tick and split into separate files to enable/disable dynamic ticks and usage of apic on the fly. It makes sense to enable dynamic ticks and usage of apic by default if they're actually built into the kernel so that is now done.

I am successfully running the dynamic tick patch on an old IBM ThinkPad A22m. When I enable the APIC support console beeps, you know bash -c 'echo -e "\a"', takes a REALLY long time to finish. I'm assuming this is a badly written program and not a kernel problem. Correct?

BTW: how do you know what HZ your machine is running at?
