    Use DEVICE_ATTR_RO for read only attributes and DEVICE_ATTR_RW for
    read/write attributes. This simplifies the source code, improves
    readbility, and reduces the chance of inconsistencies.

    The conversion was done automatically using coccinelle. It was validated
    by compiling both the old and the new source code and comparing its text,
    data, and bss size.

  • 11bf0d78c   hwmon: (fam15h_power) Introduce a cpu accumulated power reporting algorithm ... Browse Code »

    This patch introduces an algorithm that computes the average power by
    reading a delta value of “core power accumulator” register during
    measurement interval, and then dividing delta value by the length of
    the time interval.

    User is able to use power1_average entry to measure the processor power
    consumption and power1_average_interval entry to set the interval.

    A simple example:

    ray@hr-ub:~/tip$ sensors
    fam15h_power-pci-00c4
    Adapter: PCI adapter
    power1: 19.58 mW (avg = 2.55 mW, interval = 0.01 s)
    (crit = 15.00 W)

    ...

    The result is current average processor power consumption in 10
    millisecond. The unit of the result is uWatt.

    PTSC is the performance timestamp counter value in a cpu core and the
    cores in one compute unit have the fixed frequency. So it picks up the
    performance timestamp counter value of the first core per compute unit
    to measure the interval for average power per compute unit.

    This patch adds a member in fam15h_power_data which specifies the
    compute unit accumulated power. It adds do_read_registers_on_cu to do
    all the read to all MSRs and run it on one of the online cores on each
    compute unit with smp_call_function_many(). This behavior can decrease
    IPI numbers.

    Pull driver core updates from Greg Kroah-Hartman:
    "Here's the large driver core updates for 3.8-rc1.

    The biggest thing here is the various __dev* marking removals. This
    is going to be a pain for the merge with different subsystem trees, I
    know, but all of the patches included here have been ACKed by their
    various subsystem maintainers, as they wanted them to go through here.

    If this is too much of a pain, I can pull all of them out of this tree
    and just send you one with the other fixes/updates and then, after
    3.8-rc1 is out, do the rest of the removals to ensure we catch them
    all, it's up to you. The merges should all be trivial, and Stephen
    has been doing them all in linux-next for a few weeks now quite
    easily.

    Other than the __dev* marking removals, there's nothing major here,
    some firmware loading updates and other minor things in the driver
    core.

    All of these have (much to Stephen's annoyance), been in linux-next
    for a while.

    Newer BKDG[1] versions recommend a different initialization value for
    the running average range register in the northbridge. This improves
    the power reading by avoiding counter saturations resulting in bogus
    values for anything below about 80% of TDP power consumption.
    Updated BIOSes will have this new value set up from the beginning,
    but meanwhile we correct this value ourselves.
    This needs to be done on all northbridges, even on those where the
    driver itself does not register at.

    This fixes the driver on all current machines to provide proper
    values for idle load.
