CPU microcode is the latest known available version: NO
by SlackIT from LinuxQuestions.org on (#6ESZ7)
I'm running Slack 15.0, which has at this moment kernel-firmware-20230725_b6ea35f-noarch-1.
I thought the amd microcode in it, would be the latest.
But when I run spectre-meltdown-checker.sh I get this back at the terminal;
* CPU microcode is the latest known available version: NO (latest version is 0xa201025 dated 2021/10/14 according to builtin firmwares DB v273+i20230808+b6bd)
This is how I installed and setup the amd microcode;
Code:mkdir -p /tmp/amd-ucode/kernel/x86/microcode
cd /tmp/amd-ucode
cat /lib/firmware/amd-ucode/microcode_amd*.bin > kernel/x86/microcode/AuthenticAMD.bin
echo kernel/x86/microcode/AuthenticAMD.bin | bsdcpio -o -H newc -R 0:0 > /boot/amd-ucode.imgThen I ran;
Code:mkinitrd -c -F -k 5.15.131 -f ext4 -r /dev/sda1 -m ext4 -u -o /boot/initrd.gzLast cmd I ran, then I rebooted;
Code:grub-mkconfig -o /boot/grub/grub.cfgkernel-firmware-20230725_b6ea35f-noarch-1 does not have the latest amd microcode in it? The termial output from spectre-meltdown-checker.sh says the latest is dated at 2021/10/14, and I assumed the kernel-firmware in Slack 15.0 is dated 2023/07.
hmm
