Subject: [PATCH v4 2/4] target/ppc: Replace debug messages by asserts for unknown IRQ pins
Date: Mon, 20 Sep 2021 08:12:01 +0200 [thread overview]
Message-ID: <20210920061203.989563-3-clg@kaod.org> (raw)
In-Reply-To: <20210920061203.989563-1-clg@kaod.org>
If an unknown pin of the IRQ controller is raised, something is very
wrong in the QEMU model. It is better to abort.
Signed-off-by: Cédric Le Goater <clg@kaod.org>
