*	hw: Define empty HW_COMPAT_2_[23] macros	Eduardo Habkost	2015-05-31	1	-0/+6
\| \| \| \| \| \| \| \| \| \| \|	Now we can make everything consistent and define the macros even if they are still empty. Signed-off-by: Eduardo Habkost <ehabkost@redhat.com> Reviewed-by: Michael S. Tsirkin <mst@redhat.com> Signed-off-by: Michael S. Tsirkin <mst@redhat.com>

\| \| \| \| \| \| \| \| \| \| \| \|	Changing the convention to include commas inside the macros will allow macros containing empty lists to be defined and used without compilation errors.

*	virtio-pci: fix migration for pci bus master	Michael S. Tsirkin	2014-11-02	1	-0/+35
	Current support for bus master (clearing OK bit) together with the need to support guests which do not enable PCI bus mastering, leads to extra state in VIRTIO_PCI_FLAG_BUS_MASTER_BUG bit, which isn't robust in case of cross-version migration for the case when guests use the device before setting DRIVER_OK. Rip out this code, and replace it: - Modern QEMU doesn't need VIRTIO_PCI_FLAG_BUS_MASTER_BUG so just drop it for latest machine type. - For compat machine types, set PCI_COMMAND if DRIVER_OK is set. As this is needed for 2.1 for both pc and ppc, move PC_COMPAT macros from pc.h to a new common header. Cc: Greg Kurz <gkurz@linux.vnet.ibm.com> Signed-off-by: Michael S.
