platform/x86: asus-wmi: Support the hardware GPU MUX on some laptops

2022-08-25T14:23:53Z

Support the hardware GPU MUX switch available on some models. This switch can toggle the MUX between: - 0, Dedicated mode - 1, Optimus mode Optimus mode is the regular iGPU + dGPU available, while dedicated mode switches the system to have only the dGPU available.

platform/x86: asus_wmi: Support throttle thermal policy

Throttle thermal policy ACPI device is used to control CPU cooling and throttling. This patch adds sysfs entry for setting current mode and Fn+F5 hotkey that switches to next.

platform/x86: asus: Rename "fan mode" to "fan boost mode"

2019-07-17T16:07:58Z

The Asus WMI spec indicates that the function being controlled here is called "Fan Boost Mode". The user-facing documentation also calls it this. The spec uses the term "fan mode" is used to refer to other things, including functionality expected to appear on future products. We missed this before as we are not dealing with the most readable of specs, and didn't forsee any confusion around shortening the name. Rename "fan mode" to "fan boost mode" to improve consistency with the spec and to avoid a future naming conflict. There is no interface breakage here since this has yet to be included in an official kernel release. I also updated the kernel version listed under ABI accordingly.

platform/x86: asus-wmi: Switch fan boost mode

2019-06-17T12:22:47Z

The WMI exposes a write-only device ID where up to three fan modes can be switched on some laptops (TUF Gaming FX505GM). There is a hotkey combination Fn-F5 that does have a fan icon, which is designed to toggle between fan modes. The DSTS of the device ID returns information about the presence of this capability and the presence of each of the two additional fan modes as a bitmask (0x01 - overboost present, 0x02 - silent present) [1]. Add a SysFS entry that reads the last written value and updates value in WMI on write and a hotkey handler that toggles the modes taking into account their availability according to DSTS. Modes: * 0x00 - normal or balanced, * 0x01 - overboost, increased fan RPM, * 0x02 - silent, decreased fan RPM [1] Link: https://lkml.org/lkml/2019/4/12/110 Signed-off-by: Yurii Pavlovskyi Suggested-by: Daniel Drake Signed-off-by: Andy Shevchenko

asus-wmi: enable resume on lid open

2012-07-28T04:11:49Z

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//lid_resume so that userspace apps can enable/disable this feature by themselves.

eeepc-wmi: asus generic asus-wmi.ko module

2011-03-28T10:07:20Z

New Asus notebooks are using a WMI device similar to the one used in Eee PCs. Since we don't want to load eeepc-wmi module on Asus notebooks, and we want to keep the eeepc-wmi module for backward compatibility, this patch introduce a new module, named asus-wmi, that will be used by eeepc-wmi and the new Asus Notebook WMI Driver. eeepc-wmi's input device strings (device name and phys) are kept, but rfkill and led names are changed (s/eeepc/asus/). This should not break anything since rfkill are used by type or index, not by name, and the eeepc::touchpad led wasn't working correctly before 2.6.39 anyway.
