[Bug 2073554] Re: Grub2 Support for KVM on PowerVM

[Mate Kukri]

Hi,

It seems fairly straightforward to cherry-pick this, but it would be
nice to know what systems need this.

The current GRUB does work on "KVM on Power", but I suppose newer
systems need this? I just wonder what criteria is the cut-off?

  We have added required changes in grub2 to support KVM on Power. The
  patch is available in upstream grub. This patch adds support for
  Radix, Xive and Radix_gtse in Options vector5 which is required for
  KVM LPARs. KVM LPARs ONLY support Radix and not the Hash. Not enabling
  Radix on any PowerVM KVM LPARs will result in boot failure.
