Subject: [RFC v2 03/13] hw/s390x: tod: make explicit checks for accelerators when initializing
Date: Tue, 20 Apr 2021 12:36:06 +0200 [thread overview]
Message-ID: <20210420103616.32731-4-cfontana@suse.de> (raw)
In-Reply-To: <20210420103616.32731-1-cfontana@suse.de>
replace general "else" with specific checks for each possible accelerator.
Handle qtest as a NOP,
and error out for an unknown accelerator used in combination with tod.
Signed-off-by: Claudio Fontana <cfontana@suse.de>
