  • 9c9a43ed2   [CPUFREQ] return error when failing to set minfreq ... Browse Code »

    I just stumbled on this bug/feature, this is how to reproduce it:

    # echo 450000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq
    # echo 450000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq
    # echo powersave > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
    # cpufreq-info -p
    450000 450000 powersave
    # echo 1800000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq ; echo $?
    0
    # cpufreq-info -p
    450000 450000 powersave

    Here it is. The kernel refuses to set a min_freq higher than the
    max_freq but it allows a max_freq lower than min_freq (lowering min_freq
    also).

    This behaviour is pretty straightforward (but undocumented) and it
    doesn't return an error altough failing to accomplish the requested
    action (set min_freq).
    The problem (IMO) is basically that userspace is not allowed to set a
    full policy atomically while the kernel always does that thus it must
    enforce an ordering on operations.

    The attached patch returns -EINVAL if trying to increase frequencies
    starting from scaling_min_freq and documents the correct ordering of writes.

    I corrected a small error and enhanced the govenor.txt file with the
    ondemand daemon because the kernel configs link to the documentation but
    ondemand wasn't documentated. Feel free to include the patch in the
    attachment.

    Initial git repository build. I'm not bothering with the full history,
    even though we have it. We can create a separate "historical" git
    archive of that later if we want to, and in the meantime it's about
    3.2GB when imported into git - space that would just make the early
    git days unnecessarily complicated, when we don't have a lot of good
    infrastructure for it.

    Let it rip!
