fedora
Calendar Grey January 8, 2018
Dist Fedora Esm H88
Fedora 27 users can now enable early microcode support for AMD processors, ensuring better system stability during boot by modifying dracut configuration
Adds support for early microcode for **AMD CPUs family >= 0x17**

Summary

dracut contains tools to create a bootable initramfs for 2.6 Linux kernels.

Unlike existing implementations, dracut does hard-code as little as possible

into the initramfs. dracut contains various modules which are driven by the

event-based udev. Having root on MD, DM, LVM2, LUKS is supported as well as

NFS, iSCSI, NBD, FCoE with the dracut-network package.

Adds support for early microcode for **AMD CPUs family >= 0x17**. Note: Intel

CPU support is fine. To add the microcode to all your initramfs images: ``` #

dracut --regenerate-all --force ``` To only add it to the current kernel

version: ``` # dracut --force ```

su -c 'dnf upgrade dracut' at the command line.
