2024-03-07RDMA/hns: Append SCC context to the raw dump of QPCwenglianfa
SCCC (SCC Context) is a context with QP granularity that contains information about congestion control. Dump SCCC and QPC together to improve troubleshooting. When dumping raw QPC with rdmatool, there will be a total of 576 bytes data output, where the first 512 bytes is QPC and the last 64 bytes is SCCC. When congestion control is disabled, the 64 byte SCCC will be all 0. Example: $rdma res show qp -jpr [ { "ifindex": 0, "ifname": "hns_0", "data": [ 67,0,0,0... 512bytes 4,0,2... 64bytes] },... } ] Signed-off-by: wenglianfa <wenglianfa@huawei.com> Signed-off-by: Junxian Huang <huangjunxian6@hisilicon.com> Link: https://lore.kernel.org/r/20240305055257.823513-1-huangjunxian6@hisilicon.com Signed-off-by: Leon Romanovsky <leon@kernel.org>

2023-08-19RDMA/hns: Dump whole QP/CQ/MR resource in rawChengchang Tang
Currently, some fields in the QP/CQ/MR resource can be dumped by rdma-tool, but this information is not enough. It is very inconvenient to continue to expand on the current field, and it will also introduce some trouble to parse these raw data. This patch dump whole resource in raw to avoid the above problems.

2019-10-28RDMA/hns: Fix memory leak on 'context' on error return pathColin Ian King
Currently, the error return path when the call to function dev->dfx->query_cqc_info fails will leak object 'context'. Fix this by making the error return path via 'err' return return codes rather than -EMSGSIZE, set ret appropriately for all error return paths and for the memory leak now return via 'err' rather than just returning without freeing context.
