Subject: [RFC 11/12] KVM: arm/arm64: Add KVM_VGIC_V3_ADDR_TYPE_REDIST_REGION
Date: Mon, 19 Mar 2018 10:20:19 +0100 [thread overview]
Message-ID: <1521451220-27754-12-git-send-email-eric.auger@redhat.com> (raw)
In-Reply-To: <1521451220-27754-1-git-send-email-eric.auger@redhat.com>
This new attribute allows the userspace to set the base address
of a reditributor region, relaxing the constraint of having all
consecutive redistibutor frames contiguous.
