[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Minios-devel] [UNIKRAFT PATCH v2 5/9] plat/kvm: make multiboot one VMM info option
From: Florian Schmidt <florian.schmidt@xxxxxxxxx>
The VMM info is the way by which the hypervisor provides important
boot-time information that would otherwise come by the BIOS (where is my
code? How much memory is there, and at which physical addresses?).
At the moment, multiboot is the only option, but Firecracker will use a
Linux-style bootparams page instead of the multiboot info struct.
