Subject: [OASIS Issue Tracker] Created: (VIRTIO-14) Remove limit on indirect descriptors.
Remove limit on indirect descriptors.
-------------------------------------
Key: VIRTIO-14
URL: http://tools.oasis-open.org/issues/browse/VIRTIO-14
Project: OASIS Virtual I/O Device (VIRTIO) TC
Issue Type: Improvement
Reporter: Rusty Russell
Currently the length of an indirect descriptor is limited to the ringsize (so even without indirect descriptors, you'd always make progress). This is a limitation for some proposed devices, eg virtio-gl.
We probably need some limit (eg. vhost has IOV_MAX = 1024), but perhaps it should be an independent queue parameter.
