Wishlist for Xen 4.2

Wishlist for Xen 4.2

[Teo En Ming (Zhang Enming)]

Dear Xen developers,

Could you add VGA passthrough to HVM guest patches in Xen 4.2?

Thank you very much.

Yours sincerely,

Teo En Ming (Zhang Enming)

This has been discussed many times on xen-devel..

Someone needs to step up, gather all the patches, clean them up,
make sure they build/work with current xen-unstable, 
and submit for inclusion.. and of course iterate as needed.

As previously discussed on xen-devel this requires someone who is
interested in this feature to step up and prepare the patches for
upstream, posting them per
http://wiki.xen.org/wiki/SubmittingXenPatches, taking responsibility for
implementing review feedback, reposting etc.

I believe David Techer (CCd) was taking on this work but I don't think
I've seen any patches yet. David, how is it going? Are we likely to see
anything in time for 4.2? The release time table was discussed on
xen-devel last week:
http://lists.xen.org/archives/html/xen-devel/2012-03/msg00793.html

Really we need to start seeing patches this week if there is to be any
chance of these getting into 4.2.

Ian.

I am very interested in Xen VGA passthrough patches.

David Techer's Xen VGA passthrough website:

http://www.davidgis.fr/blog/index.php?2011/12/07/860-xen-42unstable-patches-for-vga-pass-through

Are his Xen VGA passthrough patches able to work with Xen 4.2-unstable 
CHANGESET 25070? I can observe that his patches only apply up to 
changeset 24888.

Thank you very much.

Yours sincerely,

Teo En Ming (Zhang Enming)

To ALL

I did my tests for 25070 yesterday And it is Ok for this revision version.

last patches are the same http://www.davidgis.fr/download/xen-4.2_rev24798_gfx-passthrough-patchs.tar.bz2


I've just forgot to update my article for this revision. (done now!).

I will not have time to use Xen processes to submit patches.

HOWEVER in the process of applying my patches, the following commands need to be run so a few files are generated.


./configure
make tools
cd tools
make clean
cd ..

then apply patches. t
hen make xen tools stubdom
then make install-xen install-tools install-stubdom


So I don't think that applying my patches could be done directly in Xen sources.
Moreover it depends on the choice done by the user.

As a wise man said "KISS" Keep IT Simple and Stupid.

 -create a directory where to put all patches somewhere in Xen sources

- create a README.first to explain how to use this patches with required commands (see above).

  I can make a resume of my article if required  in the README.first and update the wiki infos if required 

This is the simple easy why I found.

We just need to have the specific patches somewhere in the Xen sources because VGA passthrough is something very specific.

Kind regards.

David.
