Issue #2360 has been updated by Venkatesh Srinivas.


virtio and pci ===
- why is virtqueue_poll() spin-waiting on dequeueing something from a queue? Is this okay?

vballoon ===
- vtballoon_alloc_page is not correct; we need to hold the kernel object, not the vm_token, around page allocation
- the entire balloon device would benefit from conversion to the vm_balloon framework; that is the approach I am using in my tree.

vtblock ===
- get the real FreeBSD CVSID we this was imported from
- why is the disk id # in disk_ops '200'?
- are spinlocks truly the most appropriate lock for the virtio-blk device?

vtnet ===

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
