Subject: [OASIS Issue Tracker] Created: (VIRTIO-43) ccw: Support for adapter interrupts.
ccw: Support for adapter interrupts. ------------------------------------ Key: VIRTIO-43 URL: http://tools.oasis-open.org/issues/browse/VIRTIO-43 Project: OASIS Virtual I/O Device (VIRTIO) TC Issue Type: New Feature Reporter: Cornelia Huck We want to be able to use adapter interrupts instead of classic I/O interrupts for virtio-ccw for several reasons: - Less exits, since we don't need TEST SUBCHANNEL for every interrupt and can coalesce interrupts for different devices - Common guest code with zPCI - Ability to make use of irqfds For this, we need a new channel command to set up two-stage indicator bits. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://tools.oasis-open.org/issues/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
