I/OAT DMA engines are bulk memory operation offload + engines built into some Intel Server/Storage platform + CPUs.

+ +

This quarter, several enhancements were made to the driver. + The driver now avoids memory allocation in locked paths, which + should avoid deadlocking in memory pressure scenarios. Support + for Broadwell-EP devices has been added. The + "blockfill" operation and a non-contiguous 8 KB copy + operation have been added to the API. The driver can recover from + various programming errors by resetting the hardware.
