Subject: [kvm-unit-tests PATCH v2 15/16] arm/arm64: ITS: migration tests
Date: Fri, 10 Jan 2020 15:54:11 +0100 [thread overview]
Message-ID: <20200110145412.14937-16-eric.auger@redhat.com> (raw)
In-Reply-To: <20200110145412.14937-1-eric.auger@redhat.com>
This test maps LPIs (populates the device table, the collection table,
interrupt translation tables, configuration table), migrates and make
sure the translation is correct on the destination.
