Subject: [PATCH v2 1/4] hw/arm/integratorcp: Replace hw_error() by qemu_log_mask()
Date: Mon, 18 May 2020 16:03:06 +0200	[thread overview]
Message-ID: <20200518140309.5220-2-f4bug@amsat.org> (raw)
In-Reply-To: <20200518140309.5220-1-f4bug@amsat.org>

hw_error() calls exit(). This a bit overkill when we can log
the accesses as unimplemented or guest error.

When fuzzing the devices, we don't want the whole process to
exit. Replace some hw_error() calls by qemu_log_mask().
