Subject: [PATCH v2 2/4] hw/arm/pxa2xx: Replace hw_error() by qemu_log_mask()
Date: Mon, 18 May 2020 16:03:07 +0200 [thread overview]
Message-ID: <20200518140309.5220-3-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().
