Subject: [PATCH v6 2/8] target/s390x: add zpci-interp to cpu models
Date: Tue, 24 May 2022 15:02:59 -0400	[thread overview]
Message-ID: <20220524190305.140717-3-mjrosato@linux.ibm.com> (raw)
In-Reply-To: <20220524190305.140717-1-mjrosato@linux.ibm.com>

The zpci-interp feature is used to specify whether zPCI interpretation is
to be used for this guest.
