Subject: [PATCH v2 5/8] ppc/spapr: Allow FWNMI on TCG
Date: Tue, 17 Mar 2020 00:26:10 +1000 [thread overview]
Message-ID: <20200316142613.121089-6-npiggin@gmail.com> (raw)
In-Reply-To: <20200316142613.121089-1-npiggin@gmail.com>
There should no longer be a reason to prevent TCG providing FWNMI.
System Reset interrupts are generated to the guest with nmi monitor
command and H_SIGNAL_SYS_RESET. Machine Checks can not be injected
currently, but this could be implemented with the mce monitor cmd
similarly to i386.
