  • f7d770790   [CPUFREQ] Move ARM Samsung cpufreq drivers to drivers/cpufreq/ ... Browse Code »

    According to discussion of the ARM arch subsystem migration,
    ARM cpufreq drivers move to drivers/cpufreq. So this patch
    adds Kconfig.arm for ARM like x86 and adds Samsung S5PV210
    and EXYNOS4210 cpufreq driver compile in there.
    As a note, otherw will be moved.

  • 2d06d8c49   [CPUFREQ] use dynamic debug instead of custom infrastructure ... Browse Code »

    With dynamic debug having gained the capability to report debug messages
    also during the boot process, it offers a far superior interface for
    debug messages than the custom cpufreq infrastructure. As a first step,
    remove the old cpufreq_debug_printk() function and replace it with a call
    to the generic pr_debug() function.

    How can dynamic debug be used on cpufreq? You need a kernel which has
    CONFIG_DYNAMIC_DEBUG enabled.

    To enabled debugging during runtime, mount debugfs and

    $ echo -n 'module cpufreq +p' > /sys/kernel/debug/dynamic_debug/control

    for debugging the complete "cpufreq" module. To achieve the same goal during
    boot, append

    ddebug_query="module cpufreq +p"

    as a boot parameter to the kernel of your choice.

    For more detailled instructions, please see
    Documentation/dynamic-debug-howto.txt

  • 6a108a14f   kconfig: rename CONFIG_EMBEDDED to CONFIG_EXPERT ... Browse Code »

    The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option
    is used to configure any non-standard kernel with a much larger scope than
    only small devices.

    This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes
    references to the option throughout the kernel. A new CONFIG_EMBEDDED
    option is added that automatically selects CONFIG_EXPERT when enabled and
    can be used in the future to isolate options that should only be
    considered for embedded systems (RISC architectures, SLOB, etc).

    Calling the option "EXPERT" more accurately represents its intention: only
    expert users who understand the impact of the configuration changes they
    are making should enable it.

  • 1c2562459   [CPUFREQ] allow ondemand and conservative cpufreq governors to be used as default ... Browse Code »

    Depending on the transition latency of the HW for cpufreq switches, the
    ondemand or conservative governor cannot be used with certain cpufreq
    drivers. Still the ondemand should be the default governor on a wide range
    of systems. This patch allows this and lets the governor fallback to the
    performance governor at cpufreq driver load time, if the driver does not
    support fast enough frequency switching.

    Main benefit is that on e.g. installation or other systems without
    userspace support a working dynamic cpufreq support can be achieved on most
    systems by simply loading the cpufreq driver. This is especially essential
    for recent x86(_64) laptop hardware which may rely on working dynamic
    cpufreq OS support.

  • b9170836d   [CPUFREQ] Conservative cpufreq governer ... Browse Code »

    A new cpufreq module, based on the ondemand one with my additional patches
    just posted. This one is more suitable for battery environments where its
    probably more appealing to have the cpu freq gracefully increase and decrease
    rather than flip between the min and max freq's.

    N.B. Bruno Ducrot pointed out that the amd64's "do have unacceptable latency
    between min and max freq transition, due to the step-by-step requirements
    (200MHz IIRC)"; so AMD64 users would probably benefit from this too.

    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!
