From 55c4b069973196b1d9089162e31f5bd7d9f17630 Mon Sep 17 00:00:00 2001 From: Gerd Hoffmann Date: Tue, 15 Sep 2020 14:08:58 +0200 Subject: microvm/acpi: use GSI 16-23 for virtio 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.
