[ https://tools.oasis-open.org/issues/browse/VIRTIO-43?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Michael Tsirkin updated VIRTIO-43: ---------------------------------- Fix Version/s: virtio 1.0 csprd01 > ccw: Support for adapter interrupts. > ------------------------------------ > > Key: VIRTIO-43 > URL: https://tools.oasis-open.org/issues/browse/VIRTIO-43 > Project: OASIS Virtual I/O Device (VIRTIO) TC > Issue Type: New Feature > Reporter: Cornelia Huck > Assignee: Cornelia Huck > Fix For: virtio 1.0 csprd01 > > > 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 was sent by Atlassian JIRA (v6.1.1#6155)
