Subject: [PATCH v2 1/9] target/ppc: raise HV interrupts for partition table entry problems
Date: Wed, 16 Feb 2022 20:25:37 +1000	[thread overview]
Message-ID: <20220216102545.1808018-2-npiggin@gmail.com> (raw)
In-Reply-To: <20220216102545.1808018-1-npiggin@gmail.com>

Invalid or missing partition table entry exceptions should cause HV
interrupts. HDSISR is set to bad MMU config, which is consistent with
the ISA and experimentally matches what POWER9 generates.
