THAT SOLVED THE FAULTING; OUT_RING now completes under Xen.

My typo and testing mistakes.
Patched ttm_bo_mmap
vma->vm_flags |= VM_RESERVED | VM_MIXEDMAP | VM_DONTEXPAND;
if (bo->type != ttm_bo_type_device)
     vma->vm_flags |= VM_IO;

Then, put sleep and exit in libdrm OUT_RING.
The fault-handler worked fine!

One question - How to get DMA addresses for user-buffers under Xen.
Will work on that.

HUGE THANKS!
