Issue #2360 has been updated by Venkatesh Srinivas.

virtio and pci ====

* subr_sglist is a FreeBSD interface we're pulling it; thesjg has pointed out that XIO fills a similar space. We should look at implementing sglist on top of XIO, so as not to have two different ways of managing ranges of physical addresses.

virtio's vq_ring_enqueue_segments appears to be the main routine depending on the structure of an sglist; virtio-blk just primarily appends pages to a queue. Conversion there would be straightforward (to xio)
Bug #2360: Wishlist: virtio driver import

Author: Venkatesh Srinivas
Status: In Progress
Priority: Normal
Target version: 

Tim Bisson ported the FreeBSD virtio-bhyve drivers to DragonFly (https://github.com/bissont/virtio_bhyve). It'd be nice if we could import them into DragonFly. 

Status ===
I have started working on integration in the 'virtual' branch of my DragonFly tree:


x   1. Move drivers into appropriate location in source tree + rewrite makefiles
