2024-04-08platform/x86: asus-wmi: Add support for MCU powersaveLuke D. Jones
Add support for an MCU powersave WMI call. This is intended to set the MCU in to a low-power mode when sleeping. This mode can cut sleep power use by around half.

2023-07-12platform/x86: asus-wmi: expose dGPU and CPU tunables for ROGLuke D. Jones
Expose various CPU and dGPU tunables that are available on many ASUS ROG laptops. The tunables shown in sysfs will vary depending on the CPU and dGPU vendor. All of these variables are write only and there is no easy way to find what the defaults are. In general they seem to default to the max value the vendor sets for the CPU and dGPU package - this is not the same as the min/max writable value. Values written to these variables that are beyond the capabilities of the CPU are ignored by the laptop. Signed-off-by: Luke D.

2019-07-17platform/x86: asus: Rename "fan mode" to "fan boost mode"Daniel Drake
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.

2019-06-17platform/x86: asus-wmi: Switch fan boost modeYurii Pavlovskyi
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 <yurii.pavlovskyi@gmail.com> Suggested-by: Daniel Drake <drake@endlessm.com> Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.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.

2011-03-28eeepc-wmi: asus generic asus-wmi.ko moduleCorentin Chary
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.
