From: Vamsi Attunuru <[email protected]> This series adds DMA support for Marvell CN20K (O20) DPI hardware to the existing cnxk dmadev driver, building on the common ROC DPI layer used by CN9K/CN10K.
CN20K DPI is LF and ring-based: commands are posted to per-LF hardware queues rather than the legacy VF chunk-buffer model. The series introduces the ROC infrastructure for LF attach/detach, ring configuration, channel table management, and access-pair group mailbox operations, then wires the dmadev PMD to expose copy, copy-SG, fill, and enqueue/dequeue on O20. Patch 1 lays the common foundation. Patch 2 integrates O20 into the dmadev fast and slow paths. Patch 3 adds inter-process domain DMA on top of the O20 path using the dmadev access-pair group API.
