  • 5d7bd8aa7   thermal: Simplify or eliminate unnecessary set_mode() methods ... Browse Code »

    Setting polling_delay is now done at thermal_core level (by not polling
    DISABLED devices), so no need to repeat this code.

    int340x: Checking for an impossible enum value is unnecessary.
    acpi/thermal: It only prints debug messages.

  • 7f4957be0   thermal: Use mode helpers in drivers ... Browse Code »

    Use thermal_zone_device_{en|dis}able() and thermal_zone_device_is_enabled().

    Consequently, all set_mode() implementations in drivers:

    - can stop modifying tzd's "mode" member,
    - shall stop taking tzd's lock, as it is taken in the helpers
    - shall stop calling thermal_zone_device_update() as it is called in the
    helpers
    - can assume they are called when the mode truly changes, so checks to
    verify that can be dropped

    Not providing set_mode() by a driver no longer prevents the core from
    being able to set tzd's mode, so the relevant check in mode_store() is
    removed.

    Other comments:

    - acpi/thermal.c: tz->thermal_zone->mode will be updated only after we
    return from set_mode(), so use function parameter in thermal_set_mode()
    instead, no need to call acpi_thermal_check() in set_mode()
    - thermal/imx_thermal.c: regmap writes and mode assignment are done in
    thermal_zone_device_{en|dis}able() and set_mode() callback
    - thermal/intel/intel_quark_dts_thermal.c: soc_dts_{en|dis}able() are a
    part of set_mode() callback, so they don't need to modify tzd->mode, and
    don't need to fall back to the opposite mode if unsuccessful, as the return
    value will be propagated to thermal_zone_device_{en|dis}able() and
    ultimately tzd's member will not be changed in thermal_zone_device_set_mode().
    - thermal/of-thermal.c: no need to set zone->mode to DISABLED in
    of_parse_thermal_zones() as a tzd is kzalloc'ed so mode is DISABLED anyway

  • 1ee14820f   thermal: remove get_mode() operation of drivers ... Browse Code »

    get_mode() is now redundant, as the state is stored in struct
    thermal_zone_device.

    Consequently the "mode" attribute in sysfs can always be visible, because
    it is always possible to get the mode from struct tzd.

  • 0e70f466f   thermal: Enhance thermal_zone_device_update for events ... Browse Code »

    Added one additional parameter to thermal_zone_device_update() to provide
    caller with an optional capability to specify reason.
    Currently this event is used by user space governor to trigger different
    processing based on event code. Also it saves an additional call to read
    temperature when the event is received.
    The following events are cuurently defined:
    - Unspecified event
    - New temperature sample
    - Trip point violated
    - Trip point changed
    - thermal device up and down
    - thermal device power capability changed

  • e053dc909   ACPI / thermal: Remove create_workqueue() ... Browse Code »

    alloc_workqueue replaces deprecated create_workqueue().

    A dedicated workqueue has been used since the workqueue
    acpi_thermal_pm_queue with workitem &tz->thermal_check_work
    (maps to acpi_thermal_check_fn), is involved in thermal zone polling.
    Wallclock time is actually important and getting delayed in handling
    critical temperature event can actually lead to unnecessary hardware
    damage. So while this is not used during memory reclaim, we still want
    forward progress guarantee and be generally snappy in servicing it.
    Hence, WQ_MEM_RECLAIM and WQ_HIGHPRI have been used here.

    Since there are only a fixed number of work items, explicit concurrency
    limit is unnecessary here.

  • 17e8351a7   thermal: consistently use int for temperatures ... Browse Code »

    The thermal code uses int, long and unsigned long for temperatures
    in different places.

    Using an unsigned type limits the thermal framework to positive
    temperatures without need. Also several drivers currently will report
    temperatures near UINT_MAX for temperatures below 0°C. This will probably
    immediately shut the machine down due to overtemperature if started below
    0°C.

    'long' is 64bit on several architectures. This is not needed since INT_MAX °mC
    is above the melting point of all known materials.

    Consistently use a plain 'int' for temperatures throughout the thermal code and
    the drivers. This only changes the places in the drivers where the temperature
    is passed around as pointer, when drivers internally use another type this is
    not changed.

  • 6cd9e9f62   thermal: of: fix cooling device weights in device tree ... Browse Code »

    Currently you can specify the weight of the cooling device in the device
    tree but that information is not populated to the
    thermal_bind_params where the fair share governor expects it to
    be. The of thermal zone device doesn't have a thermal_bind_params
    structure and arguably it's better to pass the weight inside the
    thermal_instance as it is specific to the bind of a cooling device to a
    thermal zone parameter.

    Core thermal code is fixed to populate the weight in the instance from
    the thermal_bind_params, so platform code that was passing the weight
    inside the thermal_bind_params continue to work seamlessly.

    While we are at it, create a default value for the weight parameter for
    those thermal zones that currently don't define it and remove the
    hardcoded default in of-thermal.

    Replace direct inclusions of , and

    First of all, , and
    should not be included directly from any files that are built for
    CONFIG_ACPI unset, because that generally leads to build warnings about
    undefined symbols in !CONFIG_ACPI builds. For CONFIG_ACPI set,
    includes those files and for CONFIG_ACPI unset it
    provides stub ACPI symbols to be used in that case.

    Second, there are ordering dependencies between those files that always
    have to be met. Namely, it is required that be included
    prior to so that the acpi_pci_root declarations the
    latter depends on are always there. And which provides
    basic ACPICA type declarations should always be included prior to any other
    ACPI headers in CONFIG_ACPI builds. That also is taken care of including
    as appropriate.
