Dear GRUB folks,
On x86 microcode updates often are recommended to be applied to fix bugs. Just recently new microcode updates where published for AMD Zen 2 processors to fix “Zenbleed” [1].
Currently, these updates are shipped and applied by the firmware, and – mainly due to the proprietary and closed source x86 firmware ecosystem is slow to ship these updates and firmware updates are cumbersome to apply in this ecosystem – the operating systems like the Linux kernel [2] (but I believe also Microsoft Windows) also support to apply these updates.
Should boot loaders be able to apply these updates, so these can be applied on systems for operating systems without such a feature?
Kind regards, Paul [1]: https://lock.cmpxchg8b.com/zenbleed.html [2]: https://docs.kernel.org/arch/x86/microcode.html _______________________________________________ Grub-devel mailing list Grub-devel@gnu.org https://lists.gnu.org/mailman/listinfo/grub-devel
