Hi,
When building the 2.6.31-rc9 kernel with xen patches, obtained as per
the instructions on http://wiki.xensource.com/xenwiki/XenParavirtOps,
i.e.,
$ git clone git://git.kernel.org/pub/scm/linux/kernel/git/jeremy/
xen.git linux-2.6-xen
$ cd linux-2.6-xen
$ git checkout origin/xen/master -b xen/master
$ git pull
$ make menuconfig
I ran into the following error:

The above issue can be resolved by the following patch:

I did get the patch from the Fedora list, after googling, so maybe
somebody already has it lined up for inclusion
(http://www.mail-archive.com/fedora-xen@redhat.com/msg02913.html
)?
Hope this helps,

This seems a kind of mystery for me. Message from Jeremy (@xen-devel) ,
suggesting to add "# <linux/dma-mapping.h>" to file
"include/linux/swiotlb.h" was made about 2-3 weeks ago. Since then
kernel''s git repo got a lot of commits, moved to 2.6.31. Swiotlb issue
was tracked down and fixed by Konrad and etc.
However, include/linux/swiotlb.h stays the same.
Boris.

Having all parameters set as suggested, i still must have second "#include" in "include/linux/swiotlb.h" to build the kernel. I''ve also replaced GeForce 8500 GT by Radeon HD 4650. It helps on on F11&F12 to login into Gnome Desktop with no trouble. (Xen 3.4.1 Dom0 with 2.6.31) However, on Ubuntu 9.04 Server ( with Ubuntu Desktop installed via tasksel) login GDM screen appears to be frozen. Mouse cursor seems strange and doesn''t work at all. (Xen 3.5 Dom0 with 2.6.31) Boris. --- On Tue, 9/22/09, Jeremy Fitzhardinge <jeremy@goop.org> wrote: From: Jeremy Fitzhardinge <jeremy@goop.org> Subject: Re: [Xen-devel] Patch for 2.6.31-rc9 To: "Konrad Rzeszutek Wilk" <konrad.wilk@oracle.com> Cc: "Boris Derzhavets" <bderzhavets@yahoo.com>, xen-devel@lists.xensource.com, "Andy Georges" <andy.georges@elis.ugent.be> Date: Tuesday, September 22, 2009, 6:14 PM On 09/22/09 12:24, Konrad Rzeszutek Wilk wrote:> CONFIG_DRM=y > CONFIG_DRM_TTM=m >Ah, and TTM requires KMS_RADEON to be set.

Yes. I''ve already made a build with new version include/linux/swiotlb.h. Thanks.
