           Summary: ATI cards fail in mapping their scratch buffer.
                    ("writeback test failed")
           Product: Xen
           Version: unstable
          Platform: Other
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Linux-pv_ops dom0
        AssignedTo: xen-bugs@xxxxxxxxxxxxxxxxxxx
        ReportedBy: konrad.wilk@xxxxxxxxxx


Under Dom0:

while under native machine:

in 1 usecs


The r600_cp_init_ring_buffer function programs the GPU to map the scratch
buffer to the MMIO registers. The address is off, not sure where the
miscalculation is done.
