Hello Guix,
Here is a work-in-progress to create a service centralizing the configuration
for built-in and loadable kernel modules. The kernel module configuration
service has been implemented by making some fields from 'operating-system'
custom from the 'services' field.
Here are are some example of how to use it.
--8<---------------cut here---------------start------------->8---
;; Loadable kernel module
(simple-service 'ddcci-module kernel-module-configuration-service-type
(list (kernel-module
(name "ddcci")
(package ddcci-driver-linux)
(load? #t)
(options '("dyndbg" "delay=600")))
(kernel-module
(name "ddcci-backlight")
(blacklist? #t))))
;; Built-in kernel module
(simple-service 'intel-module
kernel-module-configuration-service-type
(list (kernel-module
(name "i915")
(options '("fastboot=1")))))
--8<---------------cut here---------------end--------------->8---
This WIP version is mainly missing the ability to configure built-in modules
trough the kernel arguments. It's the continuation of the work on
kernel-module-loader-service[1] and is needed to help fixing #41082[2].
I will try to go back to it after the GSOC network boot project.
