FLEXIBLE I/O DMA ADDRESS ALLOCATION IN VIRTUALIZED SYSTEMS |
摘要 |
An I/O DMA address may be translated for a flexible number of entries in a translation validation table (TVT) for a partitionable endpoint number, when a particular entry in the TVT is accessed based on the partitionable endpoint number. A presence of an extended mode bit can be detected in a particular TVT entry. Based on the presence of the extended mode bit, an entry in the extended TVT can be accessed and used to translate the I/O DMA address to a physical address. |
