I’m trying to get (near) realtime audio working and one of the steps I usually take on other distros is to add threadirqs to grub
sudo nano /etc/defalts/grub
Tumbleweed seems to work differently and I’ve added the line in YaST via the bootloader editing tool.
I have this:
splash=silent quiet threadirqs security=selinux selinux=1
and cpu mitigations is set to auto
It doesn’t seem to work. Any ideas? Thank you
What bootloader are you using?
The famous “it does not work”. What does not work? YaST does not modify some file you expected (which file)? The file is modified but bootloader does not use the modified value (how did you check it)? Anything else?
Hi, i’m brand new to Tumbleweed. I presume the YaST > Bootloader > Kernel options will set up the system.
When I reboot after setting this, I still have a failure message in GeekosDAW quickscan. It says threadirqs is not set
GRUB2 with BLS does not use /etc/default/grub (and it is default, not defaults). Show /etc/kernel/cmdline?
I’m still learning and yes, I can see it doesn’t use the grub location I was used to on other distros. The files don’t exist. That’s why I tried to add it in YaST.
chris@localhost:~> cat /etc/kernel/cmdline
splash=silent quiet threadirqs security=selinux selinux=1 mitigations=auto
Show
cat /proc/cmdline
it’s not showing here but is in the /etc/kernel/cmdline
I’m not sure why YaST would edit one location but boot on another. Thanks for the help btw
chris@localhost:~> cat /proc/cmdline
BOOT_IMAGE=(hd1,gpt1)/opensuse-tumbleweed/6.17.9-1-default/linux-10a0fca8649d15fc5f8c57735626635aae984d22 splash=silent quiet security=selinux selinux=1 mitigations=auto root=UUID=a6be281c-f5bb-4dd7-9ce8-53da3339e297 rootflags=subvol=@/.snapshots/1/snapshot systemd.machine_id=786b5a65b08d65a78905e8b9692b8495
Try
update-bootloader --config
Perfect, that seems to have sent the changes through and now everything is passing the checks for low latency Audio.
Could I ask why YaST didn’t update this way? What exactly did we just do?
Thank you very much!!
Apparently it is simply not implemented (for GRUB2 with BLS). You may consider bug report.
