These patches implementa PAPR extension to allow 'pseries' machine
type guests to resize their hashed page table (HPT). This allows for
more flexible memory hotplug, because we don't need to size the
initial HPT for the maximum memory size. That's particularly valuable
with (HV) KVM, since the HPT has to be host physically contiguous.
I believe this is ready to be staged for qemu-2.10 now, and assuming
there are no objections or changes suggested, I'll merge this to my
ppc-for-2.10 branch.
Since the last post this has been rebased (not trivial, due to the HPT
handling cleanups which went in recently). I've also removed an
assert which I suspect could be triggered by the guest.
David Gibson (5):
pseries: Stubs for HPT resizing
pseries: Implement HPT resizing
pseries: Enable HPT resizing for 2.10
pseries: Use smaller default hash page tables when guest can resize
pseries: Allow HPT resizing with KVM
