  • Linux support for AMD Core Performance Boost (AMD version of turbo boost)

    http://lkml.org/lkml/2010/3/22/333

    Hi all,

    here's a small patchset that implements two new performance-related
    features on AMD: Core Performance Boost and Effective Frequency
    reporting (APERF/MPERF). Details for each are to be found in the
    respective commit messages, as Andrew requested .

    5/5 overloads the /sys/devices/system/cpu/cpu3/cpufreq/scaling_cur_freq
    interface to show the actual core frequency when boosting. Let me know
    if the way it is done is agreeable.

    Thanks,
    Boris.
    Looks like it's supported on Thuban and Zosma.
