Subject: [PATCH 0/4] RfC: microvm: add second ioapic
Date: Fri, 16 Oct 2020 13:43:24 +0200 [thread overview]
Message-ID: <20201016114328.18835-1-kraxel@redhat.com> (raw)
Add a second ioapic to microvm. Gives us more IRQ lines we can
use for virtio-mmio devices. Bump number of possible virtio-mmio
devices from 8 to 24.
Gerd Hoffmann (4):
microvm: make number of virtio transports runtime configurable
microvm: make pcie irq base runtime configurable
microvm: add second ioapic
microvm: reconfigure irqs if second ioapic is available
