Compared to the last version I only added a comment to the code. - remove i440FX-xen and i440fx_write_config_xen we don't need to intercept pci config writes to i440FX anymore; - introduce PIIX3-xen and piix3_write_config_xen we do need to intercept pci config write to the PCI-ISA bridge to update the PCI link routing; - set the number of PIIX3-xen interrupts line to 128; Signed-off-by: Stefano Stabellini <stefano.stabellini@eu.citrix.com> Signed-off-by: Alexander Graf <agraf@suse.de>
