[DragonFlyBSD - Bug #2360] Wishlist: virtio driver import

[Venkatesh Srinivas via Redmine <bugtracker-admin@xxxxxxxxxxxxxxxxxxxxx>]

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)

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:

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