      acer-wmi: Add debugfs file for device detection · 81143522
      Carlos Corbacho 提交于
      Add a debugfs file for showing the full results of the method we use to
      detect devices on WMID laptops.
      
      This should be useful in the case that a Linux user gets an Acer laptop
      with 3G support (and/ or people who enjoy ripping their wireless cards out)
      so we can get some feedback on how this value changes in these cases.
      
      (At the moment, we always enable the wireless and 3G control. In the case
      of the former, this is fairly safe. In the case of the latter though,
      trying to toggle this device if it doesn't exist on a laptop causes ACPI
      warnings/ errors).
      
      To summarise: If you have an Acer laptop with a built in 3G card, please
      report back the value from this file.

      acer-wmi: Disable device autodetection on Fujitsu Siemens Amilo Li2732 · 5753dd53
      Carlos Corbacho 提交于
      The AMW0 (V1) device detection method doesn't work properly on this laptop,
      so disable it, and for other laptops that may have this problem, by
      switching on a strange GUID.

      acer-wmi: Add EC quirk for Fujitsu Siemens Amilo Li 1718 · 6f061ab5
      Carlos Corbacho 提交于
      This laptop needs a different EC quirk from the standard Acer one to read
      the wireless status.

      If the framebuffer has requested blanking, turn the backlight down. Also
      offer the user the option to do this.

      acer-wmi: Blacklist backlight on Acer Aspire 1520 & 1360 series · 9991d9f2
      Carlos Corbacho 提交于
      A newer BIOS for these laptops adds ACPI-WMI support to them. However, it does
      not add support for the backlight via the EC, and we have no way to detect
      this on older machines, so blacklist it from them.

      Make GPE disable more robust · e38e8a07
      Bob Moore 提交于
      Implemented another change for the GPE disable. We now perform a
      read-change-write of the enable register instead of simply writing out the
      cached enable mask. This will prevent inadvertent enabling of GPEs if a rogue
      GPE is received during initialization (before GPE handlers are installed.)

      ACPI: fix processor throttling set error · 3d532d5e
      Yi Yang 提交于
      http://bugzilla.kernel.org/show_bug.cgi?id=9704
      
      When echo some invalid values to /proc/acpi/processor/*/throttling,
      there isn't any error info returned, on the contray, it sets
      throttling value to some T* successfully, obviously, this is incorrect,
      a correct way should be to let it fail and return error info.
      
      This patch fixed the aforementioned issue, it also enables
      /proc/acpi/processor/*/throttling to accept such values as 't0' and 'T0',
      it also strictly limits /proc/acpi/processor/*/throttling only to accept
       "*", "t*" and "T*", "*" is the throttling state value the processor can
      support, current, it is 0 - 7.

      ACPI: fix acpi fan state set error · 6594d87e
      Yi Yang 提交于
      Under /proc/acpi, there is a fan control interface, a user can
      set 0 or 3 to /proc/acpi/fan/*/state, 0 denotes D0 state, 3
      denotes D3 state, but in current implementation, a user can
      set a fan to D1 state by any char excluding '1', '2' and '3'.
      
      For example:
      
      [root@localhost acpi]# cat /proc/acpi/fan/C31B/state
      status:                  off
      [root@localhost acpi]# echo "" > /proc/acpi/fan/C31B/state
      [root@localhost acpi]# cat /proc/acpi/fan/C31B/state
      status:                  on
      [root@localhost acpi]# echo "3" > /proc/acpi/fan/C31B/state
      [root@localhost acpi]# cat /proc/acpi/fan/C31B/state
      status:                  off
      [root@localhost acpi]# echo "xxxxx" > /proc/acpi/fan/C31B/state
      [root@localhost acpi]# cat /proc/acpi/fan/C31B/state
      status:                  on
      
      Obviously, such inputs as "" and "xxxxx" are invalid for fan state.
      
      This patch fixes this issue, it strictly limits fan state only to
      accept 0, 1, 2 and 3, any other inputs are invalid.
      
      Before applying this patch, the test result is:
      
      [root@localhost acpi]# cat /proc/acpi/fan/C31B/state
      status:                  off
      [root@localhost acpi]# echo "" > /proc/acpi/fan/C31B/state
      [root@localhost acpi]# cat /proc/acpi/fan/C31B/state
      status:                  on
      [root@localhost acpi]# echo "3" > /proc/acpi/fan/C31B/state
      [root@localhost acpi]# cat /proc/acpi/fan/C31B/state
      status:                  off
      [root@localhost acpi]# echo "xxxxx" > /proc/acpi/fan/C31B/state
      [root@localhost acpi]# cat /proc/acpi/fan/C31B/state
      status:                  on
      [root@localhost acpi]# echo "3" > /proc/acpi/fan/C31B/state
      [root@localhost acpi]# cat /proc/acpi/fan/C31B/state
      status:                  off
      [root@localhost acpi]# echo "3x" > /proc/acpi/fan/C31B/state
      [root@localhost acpi]# cat /proc/acpi/fan/C31B/state
      status:                  off
      [root@localhost acpi]# echo "-1x" > /proc/acpi/fan/C31B/state

      Fujitsu-laptop update · 20b93734
      Jonathan Woithe 提交于
      Add additional capabilities to the Fujitsu-laptop driver.
      
       * Brightness hotkey actions are sent to userspace. This can be disabled
         using a module parameter if it causes issues with models which handle
         these keys transparently in the BIOS.
      
       * Actions of additional hotkeys found on some Fujitsu models (eg: the
         suspend key and the dedicated "power on passphrase" keys) are broadcast
         to userspace.
      
       * An alternative brightness control method used by some Fujitsu models
         (for example, the S6410) is now supported, enabling software brightness
         controls on models using this method.
      
       * DMI-based module aliases are configured for the S6410 and S7020.
      
       * The current LCD brightness after booting should now be reflected in the
         standard backlight interface sysfs file (previously it was always set to
         0).  The platform brightness sysfs interface has always been fine.
      
      Thanks go to Peter Gruber who provided a significant portion of this code
      and tested various iterations of the patch on his S6410.

      This is driver for Compal Laptop: FL90/IFL90, based on MSI driver.
      
      This driver exports a few files in /sys/devices/platform/compal-laptop/:
       lcd_level - screen brightness: contains a single integer in the range 0..7 (rw)
       wlan - wlan subsystem state: contains 0 or 1 (rw)
       bluetooth - bluetooth subsystem state: contains 0 or 1 (rw)
       raw - raw value taken from embedded controller register (ro)
      
      In addition to these platform device attributes the driver registers itself
      in the Linux backlight control subsystem and is available to userspace under

      fix a deadlock issue when poking "eject" file · 26d46867

      "/sys/devices/LNXSYSTM:00/.../eject" is used to evaluate _EJx method
      and eject a device in user space.
      But system hangs when poking the "eject" file because that
      the device hot-removal code invoke the driver .remove method which will
      try to remove the "eject" file as a result.
