  • 0c872507d   thermal: consider emul_temperature while computing trend ... Browse Code »

    In case emulated temperature is in use, using the trend
    provided by driver layer can lead to bogus situation.
    In this case, debugger user would set a temperature value,
    but the trend would be from driver computation.

    To avoid this situation, this patch changes the get_tz_trend()
    to consider the emulated temperature whenever that is in use.

  • 8926fa4f9   thermal: ti-soc-thermal: add thermal data for DRA752 chips ... Browse Code »

    This patch adds the thermal data for TI DRA752 chips.
    In this change it includes (autogen):
    . Register offset definitions
    . Bitfields and masks for all registers
    . Conversion table

    Also, the thermal limits, thresholds and extrapolation
    rules are included. The extrapolation rule is simply
    add +2C as margin.

    All 5 sensors, MPU, GPU, CORE, DSPEVE and IVA, are defined
    and exposed. Only MPU has cooling device.

  • 0c12b5ac8   thermal: ti-soc-thermal: remove usage of IS_ERR_OR_NULL ... Browse Code »

    This patch changes the driver to avoid the usage of IS_ERR_OR_NULL()
    macro. This macro can lead to dangerous results, like returning
    success (0) during a failure scenario (NULL pointer handling).

    For this reason this patch is changing the driver after
    revisiting the code. These are the cases:
    i. For cases in which IS_ERR_OR_NULL() is used for checking
    return values of functions that returns either PTR_ERR()
    or a valid pointer, it has been translated to IS_ERR() check only.
    ii. For cases that a NULL check is still needed, it has been
    translated to if (!ptr || IS_ERR(ptr)).

    In order to read the history buffer, it is required to
    freeze BG FSM. This patch adds the missing piece of code
    to freeze the FSM and also a contention area to avoid
    other parts of the code to access the DTEMPs.

    For boards that provide a PCB sensor close to SoC junction
    temperature, it is possible to remove the cumulative heat
    reported by the SoC temperature sensor.

    This patch changes the extrapolation computation to consider
    an external sensor in the extrapolation equations.

  • 25cdce170   x86, mcheck, therm_throt: Process package thresholds ... Browse Code »

    Added callback registration for package threshold reports. Also added
    a callback to check the rate control implemented in callback or not.
    If there is no rate control implemented, then there is a default rate
    control similar to core threshold notification by delaying for
    CHECK_INTERVAL (5 minutes) between reports.

    Pull Ceph fixes from Sage Weil:
    "Yes, this is a much larger pull than I would like after -rc1. There

    - a few fixes for leaks and incorrect assertions
    - a few patches fixing behavior when mapped images are resized
    - handling for cloned/layered images that are flattened out from
    underneath the client

    The last bit was non-trivial, and there is some code movement and
    associated cleanup mixed in. This was ready and was meant to go in
    last week but I missed the boat on Friday. My only excuse is that I
    was waiting for an all clear from the testing and there were many
    other shiny things to distract me.

    Strictly speaking, handling the flatten case isn't a regression and
    could wait, so if you like we can try to pull the series apart, but
    Alex and I would much prefer to have it all in as it is a case real
    users will hit with 3.10."

  • b4f711ee0   time: Revert ALWAYS_USE_PERSISTENT_CLOCK compile time optimizaitons ... Browse Code »

    Kay Sievers noted that the ALWAYS_USE_PERSISTENT_CLOCK config,
    which enables some minor compile time optimization to avoid
    uncessary code in mostly the suspend/resume path could cause
    problems for userland.

    In particular, the dependency for RTC_HCTOSYS on
    !ALWAYS_USE_PERSISTENT_CLOCK, which avoids setting the time
    twice and simplifies suspend/resume, has the side effect
    of causing the /sys/class/rtc/rtcN/hctosys flag to always be
    zero, and this flag is commonly used by udev to setup the
    /dev/rtc symlink to /dev/rtcN, which can cause pain for
    older applications.

    While the udev rules could use some work to be less fragile,
    breaking userland should strongly be avoided. Additionally
    the compile time optimizations are fairly minor, and the code
    being optimized is likely to be reworked in the future, so
    lets revert this change.
