Subject: [RFC PATCH 3/5] target/ppc: Allow virtual hypervisor on CPU without HV
Date: Sun, 06 Jun 2021 17:46:35 +0200	[thread overview]
Message-ID: <72781d9157bf771bbf1c777f77ba95ae6d214094.1622994395.git.balaton@eik.bme.hu> (raw)
In-Reply-To: <cover.1622994395.git.balaton@eik.bme.hu>

Change the assert in ppc_store_sdr1() to allow vhyp to be set on CPUs
without HV bit. This allows using the vhyp interface for firmware
emulation on pegasos2.
