RDMA/erdma: Support dynamic mtu

2022-09-21T07:31:24Z

Hardware now support jumbo frame for RDMA. So we introduce a new CMDQ message to support mtu change notification. Signed-off-by: Cheng Xu Link: https://lore.kernel.org/r/20220909093822.33868-5-chengyou@linux.alibaba.com Signed-off-by: Leon Romanovsky

RDMA/erdma: Make hardware internal opcodes invisible to driver

2022-09-20T11:27:51Z

Some opcodes are used in hardware internally, and driver does not care about them. So, we change them to reserved opcodes in driver. Signed-off-by: Cheng Xu Link: https://lore.kernel.org/r/20220909093822.33868-4-chengyou@linux.alibaba.com Signed-off-by: Leon Romanovsky

RDMA/erdma: Remove redundant includes

2022-09-20T11:27:51Z

Many of erdma's includes are redundant, because they are already included indirectly by kernel headers or custom headers. So we remove all the unnecessary direct-includes. Besides, add linux/pci.h to erdma.h because it's also used in the file.

RDMA/erdma: Eliminate unnecessary casting for erdma_post_cmd_wait

2022-09-20T11:27:51Z

erdma_post_cmd_wait does not use the 'u64 *req' input parameter directly. So it is better to define it to 'void *req', and by this we can eliminate the casting when calling erdma_post_cmd_wait.

RDMA/erdma: Correct the max_qp and max_cq capacities of the device

2022-08-16T13:29:12Z

QP0 in HW is used for CMDQ, and the rest is for RDMA QPs. So the actual max_qp capacity reported to core should be max_qp (reported by HW) - 1. So does max_cq.

RDMA/erdma: Using the key in FMR WR instead of MR structure

2022-08-16T13:24:03Z

RDMA driver should get the MR key from FMR WR, not the MR structure passed in. Fixes: 155055771704 ("RDMA/erdma: Add verbs implementation") Link: https://lore.kernel.org/r/20220810014320.88026-2-chengyou@linux.alibaba.com Signed-off-by: Cheng Xu Signed-off-by: Leon Romanovsky

RDMA/erdma: Add the erdma module

2022-07-27T18:54:39Z

Add the main erdma module, which provides interface to infiniband subsystem. This commit includes a modification from Christophe, that using the bitmap API to allocate bitmaps instead of hand-writing. And the commit also fixes warnings reported by static checkers.

RDMA/erdma: Add connection management (CM) support

2022-07-27T18:54:39Z

ERDMA's transport protocol is iWarp, so the driver must support CM interface. In CM part, we use the same way as SoftiWarp: using kernel socket to set up the connection, then performing MPA negotiation in kernel. So, this part of code mainly comes from SoftiWarp, base on it, we add some more features, such as non-blocking iw_connect implementation. This commit also fixes a duplicated include issue reported by Abaci Robot.
