Title: [PATCH 0/6] virtio with config abstraction and ring
implementation
Rusty Russell wrote:
Hi all,
This patch series attempts to come closer to unifying kvm and
lguest's
usage of virtio. As these two are the first implementations we've seen,
I hope making them closer will make future ones closer too.
Drivers now unpack their own configuration: their probe()
methods are
uniform. The configuration mechanism is extensible and can be backed by
PCI, a string of bytes, or something else.
I've abstracted out the lguest ring buffer code into a common
library.
The format has changed slightly (mainly because I had an epiphany about
inter-guest I/O).
I also implemented a console (lguest needs one).
Finally, there is a working lguest implementation.
Unfortunately,
lguest is being refactored for non-i386 ports, so the virtio patches sit
at the end of the (quite long) for-2.6.24 patchqueue. Nonetheless, they
can be found at http://lguest.ozlabs.org/patches
(click on bz2 to get
the series).
Cheers!
Rusty.
Superb job, it saved me the burden of try to merge the in-house
virtio_backend.
I like the separation of the ring code, the improved descriptors and
the notify too.
Regarding the pci config space, I rather see config_ops type of
operations to let
the 390/xen/other implementations jump on our wagon.
Maybe change the offset/len type into a handle pointer and function
pointers.
The best would be to let them comment on that. I glimpsed over xen
netfront.c and I think that
the config space can be used without too many hassles
Dor.
