Subject: [PATCH 31/33] KVM: arm/arm64: Add KVM_VGIC_V3_ADDR_TYPE_REDIST_REGION
Date: Fri, 1 Jun 2018 16:27:45 +0100 [thread overview]
Message-ID: <20180601152747.23613-32-marc.zyngier@arm.com> (raw)
In-Reply-To: <20180601152747.23613-1-marc.zyngier@arm.com>
From: Eric Auger <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.
