If you want to totally turn off extraneous cpu cores, one can actually do the following:
echo 0 > /sys/devices/system/cpu/cpu1/online This only applies for cores 1..N-1 on a N core machine, i.e. you cannot turn core 0 off. This will then turn off any "Rescheduling Interrupts" since there is only 1 core running. Let me know if it reduces your power consumption. -- Kernel 2.6.24-2 causing ~1000 wakeups by "Rescheduling Interrupts" https://bugs.launchpad.net/bugs/177895 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
