Hi,
I am currently working with RDMA operations in linux kernel 6.6.23 with ConnectX-6 RNIC.
I have a question about the work completion status codes, specifically IB_WC_SUCCESS.
While searching for information, I found references stating that IB_WC_SUCCESS indicates that the RDMA operation “completed successfully”. However, these sources do not explicitly mention whether this status ensures that the data has been correctly written to the target memory location on the receiver side, or not.
When performing and RDMA WRITE operation, if the work completion status(wc.status) returns IB_WC_SUCCESS, does this status indicate that the data has been successfully written to the target memory location on the receiver side? Or does it merely confirm that the data has been successfully transmitted to the receiver’s RNIC?
Many thanks
