2023-03-20RDMA/erdma: Inline mtt entries into WQE if supportedCheng Xu
The max inline mtt count supported is ERDMA_MAX_INLINE_MTT_ENTRIES. When mr->mem.mtt_nents == ERDMA_MAX_INLINE_MTT_ENTRIES, inline mtt is also supported, fix it.

2023-03-20RDMA/erdma: Fix some typosCheng Xu
FAA is short for atomic fetch and add, not FAD. Fix this.

2022-11-24RDMA/erdma: Notify the latest PI to FW for reflushing when necessaryCheng Xu
Firmware is responsible for flushing WRs in HW, and it's a little difficult for firmware to get the latest PI of QPs, especially for RQs after QP state being changed to ERROR. So we introduce a new CMDQ command, by which driver can notify to latest PI to FW, and then FW can flush all posted WRs.

2022-11-07RDMA/erdma: Implement atomic operations supportCheng Xu
Add atomic operations support in post_send and poll_cq implementation. Also, rename 'laddr' and 'lkey' in struct erdma_sge to 'addr' and 'key', because this structure is used for both local and remote SGEs.

2022-11-07RDMA/erdma: Extend access right field of FRMR and REG MR to support atomicCheng Xu
To support atomic operations, IB_ACCESS_REMOTE_ATOMIC right should be passed to hardware for permission check. Since "access mode" field in FRMR SQE and RegMr command is never used by hw, we remove the "access mode" field, so that we can then have enough space to extend access fields.

2022-09-20RDMA/erdma: Remove redundant includesCheng Xu
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.

2022-09-20RDMA/erdma: Eliminate unnecessary casting for erdma_post_cmd_waitCheng Xu
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.

2022-08-16RDMA/erdma: Using the key in FMR WR instead of MR structureCheng Xu
RDMA driver should get the MR key from FMR WR, not the MR structure passed in.

2022-07-27RDMA/erdma: Add verbs implementationCheng Xu
The RDMA verbs implementation of erdma is divided into three files: erdma_qp.c, erdma_cq.c, and erdma_verbs.c. Internal used functions and datapath functions of QP/CQ are put in erdma_qp.c and erdma_cq.c, the rest is in erdma_verbs.c. This commit also fixes some static check warnings.
