From 3a514010aba088c9d5005b2e62048a61761a12d4 Mon Sep 17 00:00:00 2001 From: Mark Cave-Ayland Date: Fri, 13 Mar 2020 08:24:41 +0000 Subject: [PATCH] via-ide: ensure that PCI_INTERRUPT_LINE is hard-wired to its default value Some firmwares accidentally write to PCI_INTERRUPT_LINE on startup which has no effect on real hardware since it is hard-wired to its default value, but causes the guest OS to become confused trying to initialise IDE devices when running under QEMU.
