I think this approach is good to get the microcode applied as
early as possible at boot time. But on servers you usually do not want
to reboot the machine unless you do a BIOS update which will apply
the new microcode anyway. So for applying the microcode update
at runtime I would like to keep the existing API.
No, you don't want to keep the existing API and you know it. I've
explained to you last week why.
By "existing API" I mean the xen hypercall. Sorry for the confusion.
