As I understand it the CONFIG_FW_LOADER_USER_HELPER has some edge use cases, but is not needed for our hardware/firmware. > CPU is a AMD FX-9590 ( Fam15h ) > > Video is a RX480 ( Polaris 10 ) > > And, yes, both microcode updates ( Fam10h / Fam15h ) need to be builtin. Are you sure about this? I added 'amd-ucode/microcode_amd.bin' for Fam10h, rebooted and nothing changed here as far as microcode patches is concerned. I am not using savedconfig on this PC, so all amd-ucode binaries are available to be loaded from the filesystem. > Previous generation CPU updates will be builtin, even if you try to > exclude them. Fine, so following the wiki page and ONLY adding the microcode specific to the CPU family should still work. > Corbin Thanks Corbin, I wonder if despite articles about microcode patch releases to deal with spectre and what not, there are just no patches made available for my aging AMD CPUs. -- Regards, Mick
