BACK-OFF MECHANISM FOR A PERIPHERAL PAGE REQUEST LOG |
| 摘要 |
A system and method of managing requests from peripherals in a computer system are provided. In the system and method, an input/output memory management unit (IOMMU) receives a peripheral page request (PPR) from a peripheral. In response to a determination that a criterion regarding an available capacity of a PPR log is satisfied, a completion message is sent to the peripheral indicating that the PPR is complete and the PPR is discarded without queuing the PPR in the PPR log. |
