This patchset adds a dmadev driver and associated documentation to support Intel QuickData Technology devices, part of the Intel I/O Acceleration Technology (Intel I/OAT). This driver is intended to ultimately replace the current IOAT part of the IOAT rawdev driver
NOTE: This patchset has several dependencies: - v19 of the dmadev set [1] - v2 of the dmadev test suite [2] - v2 of the IDXD driver [3] [1] http://patches.dpdk.org/project/dpdk/list/?series=18629 [2] http://patches.dpdk.org/project/dpdk/list/?series=18607 [3] http://patches.dpdk.org/project/dpdk/list/?series=18658 --- v2: - Rebased on the above patchsets. - Added support for the vchan idle function. - Stop function now suspends IOAT channel to allow for reconfig. - dmadev_autotest can now be run multiple times using the IOAT driver without errors. - Added devbind updates for DMA devices - Removed some logically dead code found by coverity in the create function.
