Charge_control thresholds not found

[ghost]

Describe the bug Hi, I have installed Ubuntu 18.04 on my Matebook 13. I followed your instructions and installed the v3.2 driver. However, after installation I cannot find the "sys/class/power_supply/BAT0/chargecontrol{start,end}_threshold or /sys/devices/platform/huawei-wmi/charge_control_thresholds" files for controlling the thresholds. I tried then to upgrade to Ubuntu 19.10 to use the v3.4 driver, but I still cant find the files. I performed the installation using dkms tarball. Could you help me out?

Desktop (please complete the following information):

• Kernel [5.3]
• Distro [Ubuntu 19.10] `
• Loaded WMI modules lsmod | grep wmi snd_rawmidi 36864 1 snd_seq_midi snd_seq_device 16384 3 snd_seq,snd_seq_midi,snd_rawmidi mxm_wmi 16384 1 nouveau wmi_bmof 16384 0 intel_wmi_thunderbolt 20480 0

Maybe I did not understand your installation instructions properly, could you help me out? Thanks.

I saw there was a previous issue similar that was similar to mine, and it was solved by rebooting. However, I have also tried that but it doesnt seem to solve my problem

There is a bug with DKMS > 2.6 where it doesn't update modules that already exist in the kernel. Please try manual installation.

I tried to build it from source using your instructions: git clone https://github.com/aymanbagabas/Huawei-WMI cd Huawei-WMI make

To update use:

sudo cp huawei-wmi.ko /lib/modules/$(uname -r)/updates/ sudo depmod

To install use:

sudo make install

When I ran sudo make install, this is the error message that returned: make -C /lib/modules/5.3.0-24-generic/build/ M=/home/rusern/Huawei-WMI modules_install make[1]: Entering directory '/usr/src/linux-headers-5.3.0-24-generic' INSTALL /home/rusern/Huawei-WMI/huawei-wmi.ko At main.c:160:

That's a SSL error, shouldn't affect anything. Did you reboot?

Oh sorry. I rebooted my device, but I still dont see the files in the stated location.

What's the output of lsmod | grep wmi now that you've installed the driver manually and rebooted?

Hi, this is what I got:

lsmod | grep wmi

The driver is clearly not loaded. Closing.
