Subject: [kvm-unit-tests PATCH 3/4] s390x: cpumodel: FMT4 SCLP test
Date: Mon, 10 May 2021 15:00:14 +0000 [thread overview]
Message-ID: <20210510150015.11119-4-frankja@linux.ibm.com> (raw)
In-Reply-To: <20210510150015.11119-1-frankja@linux.ibm.com>
SCLP is also part of the cpumodel, so we need to make sure that the
features indicated via read info / read cpu info are correct.
