How to regenerate initramfs for HuC Firmware loading

English Hardware
#1

Hi.
I am trying to manually load HuC Firmware for my DG2 GPU (Intel Arc A380) as per the instructions found on the Arch Wiki: https://wiki.archlinux.org/title/Intel_graphics#Enable_GuC_/_HuC_firmware_loading
However, I’m not sure how to continue since the wiki calls to rebuild initramfs and GRUB using mkinicpio, but OpenSUSE uses dracut. What would the correct dracut command be?

Thank you.

@lavadrop just add either to grub via YaST bootloader and when saving will do it’s thing, probably the easiest… Or add the options file and run dracut -f --regenerate-all

I just added it to grub…

Thank you very much, that did it. I had forgotten about Yast bootloader completely.
