MSI Support in Xen

MSI Support in Xen

[anish]

I was trying to patch Xen 3.2 from the mercurial repository with the MSI
patches by Yunhong Jiang given at the bottom of this page :

http://lists.xensource.com/archives/html/xen-devel/2007-11/msg00157.html

The tree seems to have significantly changed, especially the
hvm_irq_dpci_mapping structure in irq.h header file. Are there any updated
patches, or can I get a version of Xen from somewhere that these patches
will successfully patch ?

We will be aiming for MSI support in 3.3, quite likely based on the Intel
patches, although that will depend on more detailed review of them.

Not as far as I know, and I'd be interested in reviewing patches that
apply to xen-unstable too.  I contacted the patch author a while ago to
see if they had an up to date copy but have heard nothing back.

Hi,

Although I am not the author, I will be working on those patches about
one week later from now. I will post the status once I finished.

Best Regards

Last time I saw them I was not blown away by the approach taken. Indeed it
looked over-complicated and a bit confused. But I may be convinceable
otherwise. In any case I will have more time coming up to 3.3 to get MSI
support beaten into a shape that I see as reasonable. Getting the existing
patches back up to unstable tip would be a good start.

Kieran,

Try reverting the unstable tree to when the patches were made. Just got 
it working last week, no problems so far.
