From 91ab2ed7221c70ed7fd09ab2665b1f0493c775a4 Mon Sep 17 00:00:00 2001 From: Igor Mammedov Date: Fri, 14 Nov 2014 11:11:44 +0000 Subject: pc: piix4_pm: init legacy PCI hotplug when running on Xen If user starts QEMU with "-machine pc,accel=xen", then compat property in xenfv won't work and it would cause error: "Unsupported bus. Bus doesn't have property 'acpi-pcihp-bsel' set" when PCI device is added with -device on QEMU CLI. From: Igor Mammedov In case of Xen instead of using compat property, just use the fact that xen doesn't use QEMU's fw_cfg/acpi tables to switch piix4_pm into legacy PCI hotplug mode when Xen is enabled.
