Re: [Xen-devel] GPU passthrough with xen-unstable-atipassthrough patch

[Gordan Bobic <gordan@xxxxxxxxxx>]

I'm trying to patch 4.2.2 using this patch, provided on a recent thread:

http://lists.xen.org/archives/html/xen-users/2013-03/msg00127.html

but the build fails:

Is there a patch against 4.2.2 somewhere, before I dig into the source?

Where is iopl() defined?
