platform/x86: asus-wmi: Add support for ROG X13 tablet mode

2023-12-13T17:26:57Z

[ Upstream commit e397c3c460bf3849384f2f55516d1887617cfca9 ] Add quirk for ASUS ROG X13 Flow 2-in-1 to enable tablet mode with lid flip (all screen rotations). Signed-off-by: Luke D.

asus-wmi: Add dgpu disable method

2023-12-13T17:26:57Z

[ Upstream commit 98829e84dc67630efb7de675f0a70066620468a3 ] In Windows the ASUS Armory Crate program can enable or disable the dGPU via a WMI call. This functions much the same as various Linux methods in software where the dGPU is removed from the device tree. However the WMI call saves the state of dGPU (enabled or not) and this then changes the dGPU visibility in Linux with no way for Linux users to re-enable it. We expose the WMI method so users can see and change the dGPU ACPI state. Signed-off-by: Luke D.

platform/x86: asus-wmi: Add support for SW_TABLET_MODE on UX360

2023-12-13T17:26:57Z

[ Upstream commit ea856ec266c1e6aecd2b107032d5b5d661f0686d ] The UX360CA has a WMI device id 0x00060062, which reports whether the lid is flipped in tablet mode (1) or in normal laptop mode (0). Add a quirk (quirk_asus_use_lid_flip_devid) for devices on which this WMI device should be used to figure out the SW_TABLET_MODE state, as opposed to the quirk_asus_use_kbd_dock_devid. Additionally, the device needs to be queried on resume and restore because the firmware does not generate an event if the laptop is put to sleep while in tablet mode, flipped to normal mode, and later awoken. It is assumed other UX360* models have the same WMI device. As such, the quirk is applied to devices with DMI_MATCH(DMI_PRODUCT_NAME, "UX360"). More devices with this feature need to be tested and added accordingly. The reason for using an allowlist via the quirk mechanism is that the new WMI device (0x00060062) is also present on some models which do not have a 360 degree hinge (at least FX503VD and GL503VD from Hans' DSTS collection) and therefore its presence cannot be relied on.

platform/x86: asus-wmi: Add support for SW_TABLET_MODE

2020-05-12T14:27:12Z

On Asus 2-in-1s with a detachable keyboard the Asus WMI interface reports if the tablet is attached to the keyboard or not. Report if the 2-in-1 is in tablet or clamshell mode to userspace by reporting SW_TABLET_MODE events to userspace. This has been tested on a T100TA, T100CHI, T100HA and T200TA.

platform/x86: asus-wmi: fix CPU fan control on recent products

2019-07-30T11:14:38Z

Previously, asus-wmi was using the AGFN interface and FAN_CTRL device for CPU fan control. However, this code has been found to be not fully working on some recent products, and having checked the spec, these interfaces are marked as being removed from future products currently in development. The replacement appears to be the CPU_FAN device, added in spec version 8.3 (March 2014) and present on many modern Asus laptops. Add support for this device, and use it whenever it is detected. The older approach based on AGFN and FAN_CTRL is used as a fallback on products that do not have such device. Other than switching between automatic and full speed, there is no fan speed control through this new interface. Signed-off-by: Daniel Drake Signed-off-by: Andy Shevchenko

platform/x86: asus-wmi: cleanup AGFN fan handling

2019-07-30T11:14:38Z

The asus-wmi driver currently uses the "AGFN" interface and the FAN_CTRL device for fan control. According to the spec, this interface is very dated and marked as pending removal from products currently in development. Clean up the way that the AGFN fan is detected and handled, also preparing the driver for the introduction of an alternate fan control method needed to support recent Asus products. Not anticipating further development of this interface, simplify the code by dropping any notion of being able to control multiple AGFN fans (this was already limited to just a single fan through only exposing a single fan in sysfs). Check for the presence of AGFN fans at probe time, simplifying the code flow in asus_hwmon_sysfs_is_visible(). Signed-off-by: Daniel Drake Signed-off-by: Andy Shevchenko
