Another month, another branch shuffle to confuse everyone ;)
I''ve added a couple of new branches:
* xen/stable-2.6.31.x - This is currently identical to xen/master.
As its name suggests, it is going to track the 2.6.31.x stable
tree. I don''t think there''ll be any more 2.6.31.x
kernels
released, so this will just have Xen-related bugfixes. Required
for pre-Xen 4/3.4.3.
* xen/stable-2.6.32.x - This is currently an alias of xen/stable.
2.6.32 is going to be a long-term maintained kernel, so this
branch will likely be active for a long time. It will get both
Linux updates and Xen bugfixes+features. Requires Xen 4 or 3.4.3.
So what about the other branches?
* xen/stable - will always be the most recent "stable" kernel.
For
now it will track stable-2.6.32.x, but when we move the main
development focus to 2.6.33 and beyond, it will track that stable
kernel. It will be the default branch for xen.git.
* xen/master - I haven''t quite worked out what to do with this in
the medium term. I''m thinking that I''ll make xen/master
an alias
for xen/stable, since people are already using it as a default
branch. At the moment its still stable-2.6.31.x.
* xen/next - Active development branch. Generally bleeding-edge.
I''m not quite ready to move xen/next into bleeding-edge phase yet. The
2.6.32 tree is still missing a few things and needs more testing before
I''m happy with it.

So you are left with this funny position of running 2.6.31.x as Dom0 and 2.6.32.x for DomU to do PCI passthrough. Should have those patches (pciback) soon enough though. _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

There were a few memory leaks but it seemed to work okay. I ported it because I was working on the frontend in GPLPV so it hasn''t had a lot of testing. I can dig up the code if anyone is interested - it was ported against 2.6.2x I think so there may be a bit of bitrot vs the current 2.6.32 pvops kernel but hopefully most of the hard work has been done.

Re: [Xen-devel] porting pvusb drivers to pvops kernel
Hi, I was preparing to post the pvops version of pvusb, but, it has not finished and is still pending. I don''t have enough time for it for the time being. I hope I can post it until the next xen release. If someone want to work for it, I''m okay with that. > I''m afraid i can''t code that well, but i still wonder if some bits could be shared with the usb over ip project (http://usbip.sourceforge.net/#about). > Where the (tcp/)ip could be swapped for a more xen specific transport protocol if required. It has had it ups and downs in development activity and I haven''t used it for a long time, and it''s in staging tree of mainline kernel for a while now. Internal of the Pvusb and the usbip are very different except for the point that they use usb drivers interface. I don''t think it''s good idea to share the code.
