| * msi-wmi: Add MSI Wind supportMaxim Mikityanskiy2013-02-241-15/+50
| | | | | | | | | | | | | | | | | | | | Add MSI Wind support to msi-wmi driver. MSI Wind has different GUID for key events, different WMI key scan codes, it does not need filtering consecutive identical events and it does not support backlight control via MSIWMI_BIOS_GUID WMI. Tested on MSI Wind U100. Signed-off-by: Maxim Mikityanskiy <maxtram95@gmail.com> Signed-off-by: Matthew Garrett <matthew.garrett@nebula.com>

| | | | | | | | | | | | | | | | | | Introduced quirk_last_pressed variable that would indicate if last_pressed is used or not. Also converted last_pressed to simple variable in order to allow keymap to be non-contiguous.

| | | | | | | | | | | | | | | | | | | | | | It seems that existing brightness control works only for old EC models. On newer ones auto_brightness access always timeouts and lcd_level always shows 0.

| * asus-wmi: update wlan LED through rfkill led triggerAceLan Kao2013-02-241-0/+76
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

This part of the emulation is not architecture specific so should not be hiding in architecture trees as it does in the Google Android tree. The constants it uses do depend on the platform and the platform creates the bus device which then talks to the emulator to ascertain the actual devices present.

* | | efi: Make 'efi_enabled' a function to query EFI facilitiesMatt Fleming2013-01-301-1/+1
| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Originally 'efi_enabled' indicated whether a kernel was booted from EFI firmware. Over time its semantics have changed, and it now indicates whether or not we are booted on an EFI machine with bit-native firmware, e.g. 64-bit kernel with 64-bit firmware. The immediate motivation for this patch is the bug report at, https://bugs.launchpad.net/ubuntu-cdimage/+bug/1040557 which details how running a platform driver on an EFI machine that is designed to run under BIOS can cause the machine to become bricked. Also, the following report, https://bugzilla.kernel.org/show_bug.cgi?id=47121 details how running said driver can also cause Machine Check Exceptions. Drivers need a new means of detecting whether they're running on an EFI machine, as sadly the expression, if (!efi_enabled) hasn't been a sufficient condition for quite some time. Users actually want to query 'efi_enabled' for different reasons - what they really want access to is the list of available EFI facilities. For instance, the x86 reboot code needs to know whether it can invoke the ResetSystem() function provided by the EFI runtime services, while the ACPI OSL code wants to know whether the EFI config tables were mapped successfully. There are also checks in some of the platform driver code to simply see if they're running on an EFI machine (which would make it a bad idea to do BIOS-y things). This patch is a prereq for the samsung-laptop fix patch.

The HWRS method takes about 12 seconds to run, and subsequent initialisation also seems to be delayed. Since we don't really need the result, don't bother calling it on init. Those who are curious can still get the result through the 'infos' device attribute. Update the comment about HWRS in show_infos().
