From 422a6e8075752bc5342afd3eace23a4990dd7d98 Mon Sep 17 00:00:00 2001 From: Bernhard Beschow Date: Sat, 25 Feb 2023 18:08:59 +0100 Subject: hw/usb/vt82c686-uhci-pci: Use PCI IRQ routing MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit According to the PCI specification, PCI_INTERRUPT_LINE shall have no effect on hardware operations. Now that the VIA south bridges implement the internal PCI interrupt router let's be more conformant to the PCI specification.
