Subject: [PATCH 0/2] target/ppc: Fixes for hash MMU for ISA v3.0
Date: Fri, 21 Jul 2023 15:02:53 +1000	[thread overview]
Message-ID: <20230721050255.100090-1-npiggin@gmail.com> (raw)

This fixes a couple of deficiencies in the v3.0 and later (POWER9, 10)
HPT MMU implementation. With these fixes, KVM is unable to boot hash
guests on powernv9/10 machines. Bare metal hash or pseries machine with
hash works, because VRMA is only used when a real hypervisor is
virtualizing a hash guest's real mode addressing.

Thanks,
Nick
