Subject: [OASIS Issue Tracker] (VIRTIO-40) ccw: Remove 'align' and use explicit addresses for used/avail.
[ https://tools.oasis-open.org/issues/browse/VIRTIO-40?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Michael Tsirkin updated VIRTIO-40:
----------------------------------
Summary: ccw: Remove 'align' and use explicit addresses for used/avail. (was: ccw: Remove 'align' and use explicit addresses for used/avail.)
Affects Version/s: virtio 0.9.X legacy
Description:
Split out ccw specific parts from VIRTIO-23
There's no reason that used and avail parts of the virtqueue need to be consecutive. They should probably be on separate cachelines, but that decision may be better made by the guest (eg. a minimal bios implementation).
Add fields to program each part separately for ccw.
