Subject: [Qemu-devel] [RFC v2 6/7] hw/arm/virt-acpi-build: Advertise one or two GICR structures
Date: Sun, 13 May 2018 16:35:13 +0200 [thread overview]
Message-ID: <1526222114-5324-7-git-send-email-eric.auger@redhat.com> (raw)
In-Reply-To: <1526222114-5324-1-git-send-email-eric.auger@redhat.com>
Depending on the number of smp_cpus we now register one or two
GICR structures.
