F44 Silverblue Intel i5-10400
So I wanted to use systemd-tmpfiles to modify parameters for the i915 kernel module but seems I’m unable to change them at runtime
To be clear, I already have a workaround by using kernel arguments with the following command: sudo rpm-ostree kargs --append i915.enable_guc=2
I just wanted to know why I can’t touch kernel modules settings through the sysfs interfaces like in some of Intel’s documentaion
What was tried
- With bash directly
echo 2 | sudo tee /sys/module/i915/parameters/enable_guc tee: /sys/module/i915/parameters/enable_guc: Permission denied - system-tmpfiles
#/etc/tmpfiles.d/99-intel-gpu-powersave.conf w /sys/module/i915/parameters/enable_guc - - - - 2
