similar to: [PATCH 0/2] virtio-ccw: new status accessor in device

These patches implement the new read status command in qemu and bump the revision to 2 (as this ccw is currently the only thing new with that revision). Patches are on top of v2 of "virtio-1/virtio-ccw related patches". Pierre Morel (2): s390x/virtio-ccw: respond to READ_STATUS command s390x/virtio-ccw: set revision 2 as maximum revision number hw/s390x/virtio-ccw.c | 20

From: Pierre Morel <pmorel at linux.vnet.ibm.com> As virtio-1 introduced the possibility of the device manipulating the status byte, revision 2 of the virtio-ccw transport introduced a means of getting the status byte from the device via READ_STATUS. Let's wire it up for revisions >= 2 and fall back to returning the stored status byte if not supported. Signed-off-by: Pierre Morel

Hi, here's the qemu patch that implements the new adapter indicators ccw in virtio-ccw and injects adapter interrupts for the devices enabled for it.

Another iteration of virtio-1 patches for qemu, as always available on git://github.com/cohuck/qemu virtio-1 This one seems to work together with the current vhost-next patches (well, I can ping :) Changes from v4: - add helpers for feature bit manipulation and checking - use 64 bit feature bits instead of 32 bit arrays - infrastructure to allow devices to offer different sets of feature bits

The following should fix it I think:
