There are quite a lot, I think the relevant files are: $ /sbin/modinfo nouveau | grep firmware | grep tu117 firmware: nvidia/tu117/acr/ucode_ahesasc.bin firmware: nvidia/tu117/acr/bl.bin firmware: nvidia/tu117/acr/ucode_asb.bin firmware: nvidia/tu117/acr/ucode_unload.bin firmware: nvidia/tu117/acr/unload_bl.bin firmware: nvidia/tu117/nvdec/scrubber.bin firmware: nvidia/tu117/gsp/gsp-535.113.01.bin firmware: nvidia/tu117/gsp/bootloader-535.113.01.bin firmware: nvidia/tu117/gsp/booter_unload-535.113.01.bin firmware: nvidia/tu117/gsp/booter_load-535.113.01.bin firmware: nvidia/tu117/gr/sw_veid_bundle_init.bin firmware: nvidia/tu117/gr/sw_method_init.bin firmware: nvidia/tu117/gr/sw_bundle_init.bin firmware: nvidia/tu117/gr/sw_nonctx.bin firmware: nvidia/tu117/gr/sw_ctx.bin firmware: nvidia/tu117/gr/gpccs_sig.bin firmware: nvidia/tu117/gr/gpccs_data.bin firmware: nvidia/tu117/gr/gpccs_inst.bin firmware: nvidia/tu117/gr/gpccs_bl.bin firmware: nvidia/tu117/gr/fecs_sig.bin firmware: nvidia/tu117/gr/fecs_data.bin firmware: nvidia/tu117/gr/fecs_inst.bin firmware: nvidia/tu117/gr/fecs_bl.bin firmware: nvidia/tu117/sec2/sig.bin firmware: nvidia/tu117/sec2/image.bin firmware: nvidia/tu117/sec2/desc.bin These should be in /lib/firmware. > If I copy /lib/modules/6.15.4-200.fc42.x86_64 from Fedora into Debian's > /lib/modules/, can I use "sudo update-grub" to update the grub boot entry > or do I need to manually edit the entry? I'm not sure if it does the right thing. Certainly it would need copying the kernel to /boot, too and then maybe `update-initramfs -k all -u` does the right thing. If it works that would result in the fedora kernel being booted with Debian firmware files only. Might be worth a try. But my thought was to edit the grub menulist item, in the assumption that your machine has both fedora and Debian installed without swapping harddisks. The above test is maybe more sensible, because when booting the fedora kernel+initramfs with Debian rootfs it's not entirely clear without further checking how relevant the firmware files are that might be in the fedora initramfs.
