Hi Tim, Could you please have a look at this bug? Thanks a lot. http://bugzilla.xensource.com/bugzilla/show_bug.cgi?id=1774 Best Regards, Yongjie Ren (Jay) _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

Does Xen 3.0.0 actually support the IOMMU on x86_64? I''ve tried building with a couple of different configurations, and it always fails if I''ve enabled CONFIG_GART_IOMMU. The problems center around undefined references to functions such as dma_alloc_coherent, dma_free_coherent, iommu_setup, iommu_hole_init, force_iommu, iommu_aperture_allowed, and so on. In all cases, changing the config to turn off GART_IOMMU (and hence enabling DUMMY_IOMMU) allows the build to proceed to a conclusion (of sorts). I''m happy if the answer is "it''s broken, use DUMMY_IOMMU"...

One more fix about PMR disable. Move PMR disable into per-iommu enable function, instead of in current iommu_setup which only takes effect on first VT-d engine. This change also enlightens S3 resume path.

1: IOMMU: properly check whether interrupt remapping is enabled 2: AMD IOMMU: only disable when certain IVRS consistency checks fail 3: VT-d: deal with 5500/5520/X58 errata Patch 1 and 2 are version 2 of a previously submitted, then withdrawn patch following up after XSA-36. Patch 3 is version 3 of a patch previously sent by Malcolm and Andrew. Signed-off-by: Jan Beulich
