      apple-gmux: Fix kconfig dependencies · f94f0f10
      Seth Forshee 提交于
      Fix the dependencies of apple-gmux to prevent it from being built-in
      when one or more of its dependencies is built as a module. Otherwise it
      can fail to build due to missing symbols.
      
      v2: Add dependency on ACPI to fix build failure when ACPI=n

      asus-wmi: record wlan status while controlled by userapp · a50bd128
      AceLan Kao 提交于
      If the user bit is set, that mean BIOS can't set and record the wlan
      status, it will report the value read from id ASUS_WMI_DEVID_WLAN_LED
      (0x00010012) while we query the wlan status by id ASUS_WMI_DEVID_WLAN
      (0x00010011) through WMI.
      So, we have to record wlan status in id ASUS_WMI_DEVID_WLAN_LED
      (0x00010012) while setting the wlan status through WMI.
      This is also the behavior that windows app will do.
      
      Quote from ASUS application engineer
      ===
      When you call WMIMethod(DSTS, 0x00010011) to get WLAN status, it may return
      
      (1) 0x00050001 (On)
      (2) 0x00050000 (Off)
      (3) 0x00030001 (On)
      (4) 0x00030000 (Off)
      (5) 0x00000002 (Unknown)
      
      (1), (2) means that the model has hardware GPIO for WLAN, you can call
      WMIMethod(DEVS, 0x00010011, 1 or 0) to turn WLAN on/off.
      (3), (4) means that the model doesn’t have hardware GPIO, you need to use
      API or driver library to turn WLAN on/off, and call
      WMIMethod(DEVS, 0x00010012, 1 or 0) to set WLAN LED status.
      After you set WLAN LED status, you can see the WLAN status is changed with
      WMIMethod(DSTS, 0x00010011). Because the status is recorded lastly
      (ex: Windows), you can use it for synchronization.
      (5) means that the model doesn’t have WLAN device.
      
      WLAN is the ONLY special case with upper rule.
      
      For other device, like Bluetooth, you just need use
      WMIMethod(DSTS, 0x00010013) to get, and WMIMethod(DEVS, 0x00010013, 1 or 0)
      to set.

      asus-nb-wmi: add wapf quirk for ASUS machines · d2044c5a
      AceLan Kao 提交于
      The BIOS of these machines will try to enable/disable wifi/bt in
      their own sqeuence. It won't read the enable/disable parameter
      in WMI command, but just iterates the wifi/bt's status described below
      1st. enable wifi, enable bt
      2nd. disable wifi, enable bt
      3rd. enable wifi, disable bt
      4th. disable wifi, disable bt
      That will totally mess up the rfkill status, since we will try to read
      wifi and bt's status and reset it again while booting up.
      
      To avoid this, these machines should set the wapf value to 4,
      that will let software totally control the wifi/bt's status and
      BIOS will do nothing instead of sending out the 0x88(KEY_RFKILL) event
      instead of 0x5e(wifi enable), 0x5f(wifi diable), 0x7d(bt enable), and
      0x7e(bt disable) through WMI.
      
      With this patch[1], it will handle the KEY_RFKILL event correctly and
      will block/unblock wifi and bt together.

      asus-wmi: enable resume on lid open · c0b91b6d
      AceLan Kao 提交于
      According to the ASUS WMI spec., to enable resume on lid open should
      use the device ID(0x00120032), but it doesn't work indeed.
      
      After discussing with ASUS' BIOS engineer, they say wake on lid open
      doesn't have a uniq device ID(0x00120032) in the BIOS. It shares the same
      device ID with deep S3(0x00120031), and the deep S3(resume on lid open)
      is disable by default.
      
      Adding this option in asus wmi sysfs
         /sys/devices/platform/<platform>/lid_resume
      so that userspace apps can enable/disable this feature by themselves.

      asus-wmi: control backlight power through WMI, not ACPI · 272c77d5
      AceLan Kao 提交于
      BugLink: https://bugs.launchpad.net/bugs/1000146
      
      Some h/w that can adjust screen brightness through ACPI functions, but
      can't turn on/off the backlight power correctly. So, we list those h/w in
      quirks and try to turn on/off the backlight power through WMI.

      Instead of using directly acpi_video_unregister(), use
      acpi_video_dmi_promote_vendor() (and make it call
      acpi_video_unregister() if needed)

      asus-wmi: use ASUS_WMI_METHODID_DSTS2 as default DSTS ID. · 63a78bb1
      Alex Hung 提交于
      According to responses from the BIOS team, ASUS_WMI_METHODID_DSTS2
      (0x53545344) will be used as future DSTS ID. In addition, calling
      asus_wmi_evaluate_method(ASUS_WMI_METHODID_DSTS2, 0, 0, NULL) returns
      ASUS_WMI_UNSUPPORTED_METHOD in new ASUS laptop PCs. This patch fixes
      no DSTS ID will be assigned in this case.
