2013-02-24asus-wmi: add display toggle quirkAceLan Kao
For machines with AMD graphic chips, it will send out WMI event and ACPI interrupt at the same time while hitting the hotkey. BIOS will notify the system the next display output mode throught WMI event code, so that windows' application can show an OSD to tell the user which mode will be taken effect. User can hit the display toggle key many times within 2 seconds to choose the mode they want. After 2 seconds, WMI dirver should send a WMIMethod(SDSP) command to tell the BIOS which mode the user chose. And then BIOS will raise another ACPI interrupt to tell the system to really switch the display mode. In Linux desktop, we don't have this kind of OSD to let users to choose the mode they want, so we don't need to call WMIMethod(SDSP) to have another ACPI interrupt. To simplify the problem, we just have to ignore the WMI event, and let the first ACPI interrupt to send out the key event. For the need, here comes another quirk to add machines with this kind of behavior. When the WMI driver receives the display toggle WMI event, and found the machin is in the list, it will do nothing and let ACPI video driver to report the key event.

2013-02-24asus-wmi: update wlan LED through rfkill led triggerAceLan Kao
For those machines with wapf=4, BIOS won't update the wireless LED, since wapf=4 means user application will take in chage of the wifi and bt. So, we have to update wlan LED status explicitly. But I found there is another wireless LED bug in launchpad and which is not in the wapf=4 quirk. So, it might be better to set wireless LED status explicitly for all machines.

2012-08-17asus-wmi: record wlan status while controlled by userappAceLan Kao
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. === Signed-off-by: AceLan Kao <acelan.kao@canonical.com> Signed-off-by: Matthew Garrett <mjg@redhat.com>
2012-07-28asus-wmi: enable resume on lid openAceLan Kao
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.

2012-03-26asus-wmi: store backlight power status for AIO machineAceLan Kao
Due to some implementation reasons, ASUS ET2012 All-in-One machines can't report the correct backlight power status, it will always return 1. To track the backlight power status correctly, we have to store the status by ourselves. BTW, by the BIOS design, the backlight power will be turn on/off sequently, no matter what the value of the parameter will be. More over, the brightness adjustment command will turn on the backlight power. Those behaviors will make us fail to track the backlight power status. For example, While we are trying to turn on the backlight power, we will send out the brightness adjustment command and then trying to figure out if we have to turn on the backlight power, then send out the command. But, the real case is that, the backlight power turns on while sending the brightness adjustment command, and then we send out the command to turn on the backlight power, it actually will turn off the backlight power and the backlight power status we recorded becomes wrong. So, we have to seperate these two commands by a if statement.

2012-03-26asus-wmi: add scalar board brightness adj. supportAceLan Kao
Some ASUS ET2012E/I All-in-One machines that use a scalar board to control the brightness, and they only accept brightness up and down command. So, I introduced a get_scalar_command() function to pass the command to the scalar board through WMI. Besides, we have to store the brightness value locally, for we need the old value to know the brightness value is increasing or decreasing. BTW, since there is no way to retrieve the actual brightness(it would be a fixed value), and the max brightness value would be fixed to 1, so we have to keep passing the brightness up/down command when we reached the max brightness value or 0.

2011-10-24platform-drivers-x86: asus-wmi: fix resource leak in asus_wmi_led_exitAxel Lin
This patch fixes wrong test for successful registered led_classdev, and also fixes a leak due to missing led_classdev_unregister call for asus->kbd_led in asus_wmi_led_exit. device_create returns &struct device pointer on success, or ERR_PTR() on error. Thus if led_classdev_register fails, led_cdev->dev is always not NULL. Thus to unregister a successful registered led_classdev, we should check (!IS_ERR_OR_NULL(asus->tpd_led.dev)) instead of (asus->tpd_led.dev). we use IS_ERR_OR_NULL instead of IS_ERR because if we havn't call led_classdev_register, the led_cdev->dev is NULL.

But there is no way to know if there is an Eee PC in that wild that is using 0x53545344 or a notebook using 0x53544344. So the driver try to guess the available DSTS method ... But most Eee PCs never return 0xFFFFFFFE when a method is not available, they return 0 instead (and that's useless). So, first, try 0x53544344 then 0x53545344.
