[PATCH 11/11] powerpc/kvm: Advertise availablity of HPT resizing on KVM HV

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This updates the KVM_CAP_SPAPR_RESIZE_HPT capability to advertise the
presence of in-kernel HPT resizing on KVM HV.  In fact the HPT resizing
isn't fully implemented, but this allows us to experiment with what's
there.
