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. This patchset passes all the driver tests added in the dmadev test suite.
NOTE: This patchset has several dependencies: - v26 of the dmadev set [1] - v7 of the dmadev test suite [2] - v7 of the IDXD driver [3] [1] http://patches.dpdk.org/project/dpdk/list/?series=19594 [2] http://patches.dpdk.org/project/dpdk/list/?series=19599 [3] http://patches.dpdk.org/project/dpdk/list/?series=19603 --- v7: - Minor rework to update from v23 to v26 of the dmadev lib. v6: - Added rawdev IOAT deprecation notice to deprecation.rst. v5: - Updated to v23 of the dmadev lib. - Removed experimental tag for driver from MAINTAINERS. - Seperated IOAT and IDXD announcements in release notes. - Added missing check for rte_dma_get_dev_id in destroy. - Fixed memleak in destroy caused by NULL pointer. - Rewrote part of the docs to reduce duplication with DMA and IDXD. - Added patch to deprecate the rawdev IOAT driver. - Reworked destroy and close functions. - Added RTE_DMA_CAPA_HANDLES_ERRORS flag for IOAT versions >=3.4. - Other minor changes to IOAT driver. v4: - Changes needed to update from dmadev v21 to v22. - Fixed 32-bit build. - Made stats reset logic easier to understand. v3: - Added burst capacity function. - Stop function now waits for suspend rather than just using a sleep. - Changed from vchan idle to vchan status function. - Other minor changes to update from dmadev v19 to v21. v2: - Rebased on the above patchsets.
