43 * USII-io-diagnosis:
44 *
45 * This diagnosis engine consumes the Psycho based IO UEs and CEs
46 * which are generated due to DMA Reads or Writes.
47 *
48 * When a UE is received it will generate the appropriate fault
49 * (defect.ultraSPARC-II.memory.nodiag). This is because we do not plan
50 * to currently add greater diagnosis capabilities for USII systems.
51 *
52 * When a CE is received we allow the legacy in kernel SERD do it's job
53 * and we just bump a counter here. The legacy SERD algorithm will print
54 * out a message and retire pages when the SERD threshold is reached.
