      Commit 3320ad99 broke mmio config space
      accesses totally on i386 - it dropped the "reg" offset to the address.

      Do not replace whole memcpy in apply alternatives · b8d3f244
      Petr Vandrovec 提交于
      apply_alternatives uses memcpy() to apply alternatives.  Which has the
      unfortunate effect that while applying memcpy alternative to memcpy
      itself it tries to overwrite itself with nops - which causes #UD fault
      as it overwrites half of an instruction in copy loop, and from this
      point on only possible outcome is triplefault and reboot.
      
      So let's overwrite only first two instructions of memcpy - as long as
      the main memcpy loop is not in first two bytes it will work fine.

      ACPI: thermal: add DMI hooks to handle AOpen's broken Award BIOS · 0b5bfa1c
      Len Brown 提交于
      Use DMI to:
      1. enable polling (BIOS thermal events are broken)
      2. disable active trip points (BIOS fan control is broken)
      3. disable passive trip point (BIOS hard-codes it too low)
      
      The actual temperature reading does work,
      and with the aid of polling, the critical
      trip point should work too.

      ACPI: thermal: create "thermal.act=" to disable or override active trip point · f8707ec9
      Len Brown 提交于
      thermal.act=-1 disables all active trip points
      in all ACPI thermal zones.
      
      thermal.act=C, where C > 0, overrides all lowest temperature
      active trip points in all thermal zones to C degrees Celsius.
      Raising this trip-point may allow you to keep your system silent
      up to a higher temperature.  However, it will not allow you to
      raise the lowest temperature trip point above the next higher
      trip point (if there is one).  Lowering this trip point may
      kick in the fan sooner.
      
      Note that overriding this trip-point will disable any BIOS attempts
      to implement hysteresis around the lowest temperature trip point.
      This may result in the fan starting and stopping frequently
      if temperature frequently crosses C.
      
      WARNING: raising trip points above the manufacturer's defaults
      may cause the system to run at higher temperature and shorten
      its life.

      ACPI: thermal: create "thermal.nocrt" to disable critical actions · f5487145
      Len Brown 提交于
      thermal.nocrt=1 disables actions on _CRT and _HOT
      ACPI thermal zone trip-points.  They will be marked
      as <disabled> in /proc/acpi/thermal_zone/*/trip_points.
      
      There are two cases where this option is used:
      
      1. Debugging a hot system crossing valid trip point.
      
         If your system fan is spinning at full speed,
         be sure that the vent is not clogged with dust.
         Many laptops have very fine thermal fins that are easily blocked.
      
         Check that the processor fan-sink is properly seated,
         has the proper thermal grease, and is really spinning.
      
         Check for fan related options in BIOS SETUP.
         Sometimes there is a performance vs quiet option.
         Defaults are generally the most conservative.
      
         If your fan is not spinning, yet /proc/acpi/fan/
         has files in it, please file a Linux/ACPI bug.
      
         WARNING: you risk shortening the lifetime of your
         hardware if you use this parameter on a hot system.
         Note that this refers to all system components,
         including the disk drive.
      
      2. Working around a cool system crossing critical
         trip point due to erroneous temperature reading.
      
         Try again with CONFIG_HWMON=n
         There is known potential for conflict between the
         the hwmon sub-system and the ACPI BIOS.
         If this fixes it, notify lm-sensors@lm-sensors.org
         and linux-acpi@vger.kernel.org
      
         Otherwise, file a Linux/ACPI bug, or notify
         just linux-acpi@vger.kernel.org.

      ACPI: thermal: create "thermal.psv=" to override passive trip points · a70cdc52
      Len Brown 提交于
      "thermal.psv=-1" disables passive trip points
      for all ACPI thermal zones.
      
      "thermal.psv=C", where 'C' is degrees Celsius,
      overrides all existing passive trip points
      for all ACPI thermal zones.
      
      thermal.psv is checked at module load time,
      and in response to trip-point change events.
      
      Note that if the system does not deliver thermal zone
      temperature change events near the new trip-point,
      then it will not be noticed.  To force your custom
      trip point to be noticed, you may need to enable polling:
      eg. thermal.tzp=3000 invokes polling every 5 minutes.
      
      Note that once passive thermal throttling is invoked,
      it has its own internal Thermal Sampling Period (_TSP),
      that is unrelated to _TZP.
      
      WARNING: disabling or raising a thermal trip point
      may result in increased running temperature and
      shorter hardware lifetime on some systems.

      ACPI: thermal: expose "thermal.tzp=" to set global polling frequency · 730ff34d
      Len Brown 提交于
      Thermal Zone Polling frequency (_TZP) is an optional ACPI object
      recommending the rate that the OS should poll the associated thermal zone.
      
      If _TZP is 0, no polling should be used.
      If _TZP is non-zero, then the platform recommends that
      the OS poll the thermal zone at the specified rate.
      The minimum period is 30 seconds.
      The maximum period is 5 minutes.
      
      (note _TZP and thermal.tzp units are in deci-seconds,
       so _TZP = 300 corresponds to 30 seconds)
      
      If _TZP is not present, ACPI 3.0b recommends that the
      thermal zone be polled at an "OS provided default frequency".
      
      However, common industry practice is:
      1. The BIOS never specifies any _TZP
      2. High volume OS's from this century never poll any thermal zones
      
      Ie. The OS depends on the platform's ability to
      provoke thermal events when necessary, and
      the "OS provided default frequency" is "never":-)
      
      There is a proposal that ACPI 4.0 be updated to reflect
      common industry practice -- ie. no _TZP, no polling.
      
      The Linux kernel already follows this practice --
      thermal zones are not polled unless _TZP is present and non-zero.
      
      But thermal zone polling is useful as a workaround for systems
      which have ACPI thermal control, but have an issue preventing
      thermal events.  Indeed, some Linux distributions still
      set a non-zero thermal polling frequency for this reason.
      
      But rather than ask the user to write a polling frequency
      into all the /proc/acpi/thermal_zone/*/polling_frequency
      files, here we simply document and expose the already
      existing module parameter to do the same at system level,
      to simplify debugging those broken platforms.
      
      Note that thermal.tzp is a module-load time parameter only.

      "thermal.off=1" disables all ACPI thermal support at boot time.
      
      CONFIG_ACPI_THERMAL=n can do this at build time.
      "# rmmod thermal" can do this at run time,
      as long as thermal is built as a module.
      
      WARNING: On some systems, disabling ACPI thermal support
      will cause the system to run hotter and reduce the
      lifetime of the hardware.
