Mlx5 Adapters's Programming Manual

Infrastructure & Networking Adapters and Cables Ethernet Adapter Cards
1

I’m trying to understand the driver code (either that in kernel module or rdma_core) of a mlx5 nic under RDMA (RoCE v2) network.
I need a manual or document for better understanding the behavior of the program. But I can only find one named Mellanox Adapters Programmer’s Reference Manual (PRM) Rev 0.40, which only supports connectX-4 and seemingly not enough for understanding the driver behavior. Are there any other newer adapter programming guides?

Thank you for your assistance.
