v 3.1 not working on MateBook 13

[nekr0z]

After update to driver v 3.1 additional keys (WiFi switch, micmute, PCmanager) and micmute LED stopped working on MateBook 13. Batpro and fnlock functionality still available.

Hmm.. that's strange. Does it register the input driver? What's the output of lsmod|grep wmi, dmesg|grep wmi, and sudo evtest. Do you have leds under /sys/devices/platform/huawei-wmi/? Is there a platform::micmute?

[aymanbagabas]

Could you try using DKMS from here.

sudo unzip huawei-wmi-3.1.zip -d /usr/src/
sudo dkms add huawei-wmi/3.1
sudo dkms install huawei-wmi/3.1

Edit: use sudo dkms autoinstall -m huawei-wmi/3.1 if you want it autoinstall

[nekr0z]

Does it register the input driver?

Ermmm... Maybe. Not sure. How do I check? ;-)

What's the output of lsmod|grep wmi

That's better...

Do you have leds under /sys/devices/platform/huawei-wmi/?

And here's where the weird part starts. There is no huawei-wmi under /sys/devices/platform/. At all.

However, matebook-applet successfully reads and writes... Oh! Oh! Disregard my previous comment on how batpro levels and fnlock work, they don't! The applet falls back to using scripts, that's what's happening.

Could you try using DKMS from here.

Hangs forever on depmod...

[aymanbagabas]

Ahhh you got a kernel panic! Can I see you full dmesg? The module didn't get probed due to error.

[nekr0z]

Ahhh you got a kernel panic!

Yep, I looked into it more closely, and it's all shambles with 3.1: sometimes it wouldn't even boot, attempting to kill init, other times it wouldn't reboot correctly, requiring the SysRq REISUB dance (thank heavens for FnLock ;))) No such behaviour with 3.0.

Can I see you full dmesg?

Why not, here you go.

[aymanbagabas]

Fixed in v3.2
Thank you!

[nekr0z]

Yep, works. Thank you! Keep up the awesome work!

@aymanbagabas I tried to install 'huawei-wmi/3.2' in three ways (rpm, tar.gz and build from source), but "/sys/devices/platform/huawei-wmi" doesn’t appear :(
