Yes, Fedora does provide intel and amd x86 processor microcode updates. (in linux-firmware (amd (/lib/firmware/amd-ucode), and intel (microcode-ctl) (/lib/firmware/intel-ucode)) And it uses linux early microcode way of loading microcode (It is prepended (at least I think it is) to initramfs): [bgrubic@quad ~]$ cpio -t -F initramfs-4.11.3-300.fc26.x86_64.img . early_cpio kernel kernel/x86 kernel/x86/microcode kernel/x86/microcode/GenuineIntel.bin 58 blocks Also on boot (kernel log) you possibly can see something like this: [ 0.000000] microcode: microcode updated early to revision 0xba, date = 2010-10-03 [ 0.810945] microcode: sig=0x6fb, pf=0x10, revision=0xba [ 0.811007] microcode: Microcode Update Driver: v2.2. _______________________________________________ users mailing list -- users@lists.fedoraproject.org To unsubscribe send an email to users-le...@lists.fedoraproject.org
