[ http://tools.oasis-open.org/issues/browse/VIRTIO-43?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=35418#action_35418 ] Cornelia Huck commented on VIRTIO-43: ------------------------------------- Current proposal: https://lists.oasis-open.org/archives/virtio/201310/msg00160.html > 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
