| 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. | |
