<title>[PATCH 0/6] virtio with config abstraction and ring
implementation</title>
<!-- Converted from text/plain format -->
<p><font size="2">Hi all,<br>
<br>
This patch series attempts to come closer to unifying kvm and
lguest's<br>
usage of virtio. As these two are the first implementations we've seen,<br>
I hope making them closer will make future ones closer too.<br>
<br>
Drivers now unpack their own configuration: their probe()
methods are<br>
uniform. The configuration mechanism is extensible and can be backed by<br>
PCI, a string of bytes, or something else.<br>
<br>
I've abstracted out the lguest ring buffer code into a common
library.<br>
The format has changed slightly (mainly because I had an epiphany about<br>
inter-guest I/O).<br>
<br>
I also implemented a console (lguest needs one).<br>
<br>
Finally, there is a working lguest implementation.
Unfortunately,<br>
lguest is being refactored for non-i386 ports, so the virtio patches sit<br>
at the end of the (quite long) for-2.6.24 patchqueue. Nonetheless, they<br>
can be found at <a moz-do-not-send="true"
href="http://lguest.ozlabs.org/patches">http://lguest.ozlabs.org/patches</a>
(click on bz2 to get<br>

<br>
Cheers!<br>

Superb job, it saved me the burden of try to merge the in-house
virtio_backend.<br>
<br>
I like the separation of the ring code, the improved descriptors and
the notify too.<br>
Regarding the pci config space, I rather see config_ops type of
operations to let <br>
the 390/xen/other implementations jump on our wagon.<br>
<br>
Maybe change the offset/len type into a handle pointer and function
pointers.<br>
The best would be to let them comment on that. I glimpsed over xen
netfront.c and I think that<br>
the config space can be used without too many hassles<br>
