Subject: [PATCH v2 13/13] microvm/acpi: use GSI 16-23 for virtio
Date: Tue, 5 May 2020 15:43:05 +0200 [thread overview]
Message-ID: <20200505134305.22666-14-kraxel@redhat.com> (raw)
In-Reply-To: <20200505134305.22666-1-kraxel@redhat.com>
With ACPI enabled and IO-APIC being properly declared in the ACPI tables
we can use interrupt lines 16-23 for virtio and avoid shared interrupts.
With acpi disabled we continue to use lines 8-15.
