Hi,

Since 2.6.25-rc1 I have a lot of wakeups/s (≈134191,4) and spend 100% in C0. It worked fine with 2.6.24 and commandline nolapic. Without nolapic I had 80k wakeups/s after some time, but not right from the start like now.

What useful information can I provide?

We have a regression from 2.6.24, apparently interrupts-related.

Let's see what the experts say.

Thanks,

After a lot of bisecting I've found the bad commit: 

9b12e18cdc1553de62d931e73443c806347cd974 is first bad commit
commit 9b12e18cdc1553de62d931e73443c806347cd974
Author: venkatesh.pallipadi@intel.com <venkatesh.pallipadi@intel.com>
Date:   Thu Jan 31 17:35:05 2008 -0800

    ACPI: cpuidle: Support C1 idle time accounting
    
    Show C1 idle time in /sysfs cpuidle interface. C1 idle time may not
    be entirely accurate in all cases. It includes the time spent
    in the interrupt handler after wakeup with "hlt" based C1. But, it will
    be accurate with "mwait" based C1.


Reverting the commit brings my laptop back to C2.

Thanks for the bisect info. I will look at the bad side effects that patch may be having and I should have a patch for you to test later today....

Thanks,

One question. Do you have CONFIG_CPU_IDLE enabled in your confg?

Thanks,

Can you try with it disabled and check whether you still see the
problem?

Thanks,

Yup you are right, that fixes the problem as well.

Jan replied later on this issue that he is not able to reproduce this problem
any more. Looking at the above, I could see a potential problem where
menu governor may get confused by the C-state residency time from poll
idle or C1 idle, where this timing info is not accurate. This inaccuracy is
due to interrupts being handled before we account for C-state exit.

Patch below fixes this and is needed regardless of the issue pointed out by
Jan Willies here. But, I am suspecting that the patch will also fix the
problem reported by Jan.

Do not mark TIME_VALID for CO poll state.
Mark C1 time as valid only with mwait (CSTATE_FFH) entry method.

This makes governors use the timing information only when it is correct and
eliminates any wrong policy decisions that may result from invalid timing
information.
