Subject: Version Control Commit by mstsirkin


Author: mstsirkin
Date: 2016-10-10 19:37:25 +0000 (Mon, 10 Oct 2016)
New Revision: 579
Web View: https://tools.oasis-open.org/version-control/browse/wsvn/virtio/?rev=579&sc=1

Log:
ccw: add CCW_CMD_READ_STATUS

ccw currently allows the driver to update the status via the
CCW_CMD_WRITE_STATUS command; however, it does not allow the driver to
retrieve the current status at the device, which is needed to properly
support DEVICE_NEEDS_RESET.

Therefore, provide a new command CCW_CMD_READ_STATUS allowing the driver
to retrieve the device status. Provide this command when revision 2 has
been negotiated.
