Subject: [kvm-unit-tests PATCH v2 10/16] arm/arm64: ITS: its_enable_defaults
Date: Fri, 10 Jan 2020 15:54:06 +0100	[thread overview]
Message-ID: <20200110145412.14937-11-eric.auger@redhat.com> (raw)
In-Reply-To: <20200110145412.14937-1-eric.auger@redhat.com>

its_enable_defaults() is the top init function that allocates all
the requested tables (device, collection, lpi config and pending
tables), enable LPIs at distributor level and ITS level.

gicv3_enable_defaults must be called before.
