Patches with 3 minor rejects against -rc6-mm1, boots, and seems to work well on my Dell Latitude C840 laptop - although running at full load with seti@home causes the expected 250 timer ticks/sec, running a mostly-idle X session only gets about 117, and having xmms and a few other things running it hits about 170 tics/sec. I've had the CPU speed bounce between 1.2G and 1.6G a few times and it didn't seem to blink either. Even NTP is happy with what it sees.. ;)
Need to rebuild with CONFIG_HZ=1000 and see what it does, and see what it does to actual power consumption.
Minor nit: The implementation of /sys/devices/system/timer/timer0/dyn_tick_state violates the one-value-per-file rule for sysfs. I suspect this needs to become a directory with 3-4 files in it, each containing one value. [unhandled content-type:application/pgp-signature] | |
