From mboxrd@z Thu Jan 1 00:00:00 1970 From: Nicholas Piggin Date: Mon, 05 Apr 2021 01:19:42 +0000 Subject: [PATCH v6 42/48] KVM: PPC: Book3S HV P9: Allow all P9 processors to enable nested HV Message-Id: <20210405011948.675354-43-npiggin@gmail.com> List-Id: References: <20210405011948.675354-1-npiggin@gmail.com> In-Reply-To: <20210405011948.675354-1-npiggin@gmail.com> MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: kvm-ppc@vger.kernel.org Cc: linuxppc-dev@lists.ozlabs.org, Nicholas Piggin All radix guests go via the P9 path now, so there is no need to limit nested HV to processors that support "mixed mode" MMU. Remove the restriction.
