Hi Timur, I gave this a quick test on TU117, but it is looking for a firmware file that is not on disk. Should I be updating linux-firmware? Or something else is wrong? NovaCore 0000:01:00.0: Direct firmware load for nvidia/tu117/gsp/gen_bootloader-570.144.bin failed with error -2 NovaCore 0000:01:00.0: WPR2 region not created after running FWSEC-FRTS NovaCore 0000:01:00.0: probe with driver NovaCore failed with error -5 thanks, -- John Hubbard > > There is also partial support for GA100, but it's currently not > fully implemented.
