NOTE: Version v2.0 is the one in mainline kernel >= 5.0, this repository is used fortesting and development purposes. v3.3 has been merged in kernel 5.5

This driver adds support for some of the missing features found on Huaweilaptops running linux. It implements Windows Management Instrumentation (WMI)device mapping to kernel. Supported features are:

• Function hotkeys, implemented in v1.0
• Micmute LED, implemented in v2.0. Updated in v3.0 to work with newer laptops.
• Battery protection, implemented in v3.0. Updated in v3.3 to use battery charge API.
• Fn-lock, implemented v3.0.

Battery protection can accessed from either/sys/class/power_supply/BAT0/charge_control_{start,end}_threshold or/sys/devices/platform/huawei-wmi/charge_control_thresholds

Fn-lock can be accessed from/sys/devices/platform/huawei-wmi/fn_lock_state

This driver requires kernel >= 5.1. If you're on kernel <= 5.0, please refer totagv1.0 for kernel < 5.0 or tagv3.2 if you're running version 5.0.

Check outmatebook-applet for a GUIto control Fn-lock and battery protection.

Make sure you're using kernel >= 5.0.You can get this driver fromhere if you want to useDKMS modules for easy installation.

Install the RPM package providedhere.

Note: changeVER to the desired module version.

1. Grabhuawei-wmi-VER-source-only.dkms.tar.gz fromhere
2. Add dkms tarball and install module

sudo dkms ldtarball --archive=huawei-wmi-VER-source-only.dkms.tar.gzsudo dkms install huawei-wmi/VER

3. Reboot

1. Make sure you have your kernel headers. In Fedora that would be:

sudo dnf install kernel-headers kernel-devel

Should be similar in other distributions.2. Clone andupdate /install the module.

git clone https://github.com/aymanbagabas/Huawei-WMIcd Huawei-WMImake# To update use:sudo cp huawei-wmi.ko /lib/modules/$(uname -r)/updates/sudo depmod# To install use:sudo make installreboot

This method overwrites the exsiting version ofhuawei-wmi that comes withkernel 5.0. You have to redo it everytime the kernel gets updated.

NOTE: Ignore this if you're runningsystemd-udev > 240.

One of the keys,micmute, wouldn't work after inserting the module and that isdue to an issue with X.Org. The solution would be to remap it to usingudevhwdb tables.Copy99-Huawei.hwdb to/etc/udev/hwdb.d/ then update the hwdb tables:

sudo udevadm --debug hwdb --update; sudo udevadm trigger
