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.

...that command does not fail, it follows that this is not a substantive change so it can be fixed in an errata. So the new command would have to be optional, please open two issues in the TC: one documenting that driver must check WRITE_STATUS and device can fail WRITE_STATUS, and another for adding READ_STATUS (which will have to wait until the next CS). -- MST

I think I need to contemplate that a bit more. The problem with a new READ_STATUS is that it is, by nature, an asynchronous command (as all ccw commands are - the Linux guest driver uses a simple wrapper that makes it appear synchronous). This mean...
