[Xen-devel] IOMMU support: __direct_remap_pfn_range() fails 
| I am working on getting IOMMU support for AMD64.
Thanks to the help of Jun Nakajima, Jerome Young,
and Keir Frasier, I have managed to get the
aperture detected and initialized.  However,
the agpgart code is still failing.
I have tracked the problem down to line 92
of ioremap.c, in __direct_remap_pfn_range().
The failing instruction is a call to
HYPERVISOR_mmu_update().  
I'm not familiar enough with the Xen hypervisor
code to debug the problem further.  Does anyone
have suggestions for how I can debug this problem?
