Description christian barranco 2023-12-27 15:19:06 CET 
Description of problem:
In order to run MControlCenter, which is a neat Free and Open Source GNU/Linux application that allows to change the settings of MSI laptops, it is required to have ec_sys module with option write_support=1
It means the ec_sys kernel module needs to be included in the kernel; alternatively, it looks like the acpi_ec kernel module would be suitable as well.

Is it something which can be added to our kernel?


Link to MControlCenter: https://github.com/dmitry-s93/MControlCenter
I just packaged it and it went smoothly. It starts well but it is useless unless the mentioned modules are loaded.

Thanks!

Running m9 with the server flavor of the kernel here.
# zgrep EC /proc/config.gz|grep -i sys
CONFIG_FB_SYS_FILLRECT=y
CONFIG_CROS_EC_SYSFS=m
CONFIG_RPCSEC_GSS_KRB5_CRYPTOSYSTEM=y

# locate ec|grep -i sys|grep '\.ko\.'|sort -V|head -n 1
/usr/lib/modules/6.5.13-server-1.mga9/kernel/drivers/platform/chrome/cros_ec_sysfs.ko.xz

Try running "modprobe -v cros_ec_sysfs". If that fixes it add a file to
/etc/modules-load.d/ with a file name ending with .conf, and one line with
cros_ec_sysfs

If loading that module doesn't fix it, it will likely require getting a dkms
version of the needed module, from
https://github.com/junocomp/ec-sys-dkms/blob/main/README.md

If that fixes the issue, change this to a new package request for the dkms
module.

Thank you so much Dave for these hints.
From a packaging perspective, should I go directly to the dkms additional package?
Comment 3 Dave Hodgins 2023-12-28 01:39:18 CET 
I'd try loading cros_ec_sysfs first, otherwise yes go for adding the dkms
package as it's needed for hardware support.

Hi. Loading cros_ec_sysfs doesn't help. I will give a try to package the dkms.
Comment 5 christian barranco 2023-12-29 10:14:00 CET 
Hi. The package of MControlCenter is ready, bringing a dkms package for ec_sys with it.

Just tested on a MSI Modern 15 B7M laptop.

Ok to push into Cauldron?
