From aa0c9aec575f6dba4e6548ad9e5de1b1899d843e Mon Sep 17 00:00:00 2001 From: Bernhard Beschow Date: Sat, 7 Oct 2023 14:38:37 +0200 Subject: hw/i386/pc_piix: Make PIIX4 south bridge usable in PC machine QEMU's PIIX3 implementation actually models the real PIIX4, but with different PCI IDs. Usually, guests deal just fine with it. Still, in order to provide a more consistent illusion to guests, allow QEMU's PIIX4 implementation to be used in the PC machine.
