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 Modified: trunk/content.tex 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.
