DEFERRING REGISTRATION FOR DMA OPERATIONS |
| 摘要 |
Systems and methods for deferring registration for Direct Memory Access (DMA) operations. An example method may comprise: receiving a memory region registration request identifying a memory region for a direct memory access (DMA) operation; generating a local key for the memory region; receiving a DMA work request referencing the local key; and responsive to determining that an amount of pinned memory is below a threshold, registering the memory region for DMA transfer. |

1. A method, comprising:
receiving, by a processing device, a memory region registration request identifying a memory region for a direct memory access (DMA) operation; generating a local key for the memory region; receiving a DMA work request referencing the local key; and responsive to determining that an amount of pinned memory is below a threshold, registering the memory region for DMA transfer. |
