Subject: [PATCH v0 0/3] dma/cnxk: add CN20K (O20) DPI DMA and inter-process domain support
Date: Sat, 29 Aug 2026 16:24:06 +0530 [thread overview]
Message-ID: <20260829105409.1160766-1-vattunuru@marvell.com> (raw)
From: Vamsi Attunuru <vattunuru@marvell.com>
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.

common/cnxk: add O20 DPI DMA support
dma/cnxk: add O20 DPI DMA support
dma/cnxk: enable inter process domain DMA support
