Subject: [PATCH for-next 0/3] RDMA/erdma: Add DMA-BUF memory registration
Date: Thu,  7 May 2026 13:34:18 +0800	[thread overview]
Message-ID: <20260507053437.46211-1-boshiyu@linux.alibaba.com> (raw)

Hi,

This patch series adds DMA-BUF memory registration support to the erdma
driver:

- #1 renames get/put_mtt_entries to erdma_mem_init/uninit to better reflect
     their purpose of initializing the struct erdma_mem.
- #2 introduces struct erdma_mem_init_attr to pass parameters to
     erdma_mem_init(), improving code maintainability and preparing for
     DMA-BUF support.
- #3 implements erdma_reg_user_mr_dmabuf() to enable DMA-BUF based user
     memory registration using ib_umem_dmabuf_get_pinned().

Thanks,
Boshi Yu
