Subject: [PATCH v6 10/20] microvm/acpi: use GSI 16-23 for virtio
Date: Wed, 26 Aug 2020 12:52:44 +0200 [thread overview]
Message-ID: <20200826105254.28496-11-kraxel@redhat.com> (raw)
In-Reply-To: <20200826105254.28496-1-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 5-12.
