Subject: [PULL 08/20] via-ide: ensure that PCI_INTERRUPT_LINE is hard-wired to its default value
Date: Tue, 17 Mar 2020 19:23:17 -0400 [thread overview]
Message-ID: <20200317232329.22362-9-jsnow@redhat.com> (raw)
In-Reply-To: <20200317232329.22362-1-jsnow@redhat.com>
From: Mark Cave-Ayland <mark.cave-ayland@ilande.co.uk>
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.
