Utilize the -dd flag (driver-specific details) in the rdmatool to view driver-specific QPs which are not exposed yet. Add the netlink attribute to mark request to convey driver details and use it to return QP subtype as a string. $ rdma resource show qp link ibp8s0f1 link ibp8s0f1/1 lqpn 360 type UD state RTS sq-psn 0 comm [mlx5_ib] link ibp8s0f1/1 lqpn 0 type SMI state RTS sq-psn 0 comm [ib_core] link ibp8s0f1/1 lqpn 1 type GSI state RTS sq-psn 0 comm [ib_core] $ rdma resource show qp link ibp8s0f1 -dd link ibp8s0f1/1 lqpn 360 type UD state RTS sq-psn 0 comm [mlx5_ib] link ibp8s0f1/1 lqpn 465 type DRIVER subtype REG_UMR state RTS sq-psn 0 comm [mlx5_ib] link ibp8s0f1/1 lqpn 0 type SMI state RTS sq-psn 0 comm [ib_core] link ibp8s0f1/1 lqpn 1 type GSI state RTS sq-psn 0 comm [ib_core] $ rdma resource show 0: ibp8s0f0: pd 3 cq 4 qp 3 cm_id 0 mr 0 ctx 0 srq 2 1: ibp8s0f1: pd 3 cq 4 qp 3 cm_id 0 mr 0 ctx 0 srq 2 $ rdma resource show -dd 0: ibp8s0f0: pd 3 cq 4 qp 4 cm_id 0 mr 0 ctx 0 srq 2 1: ibp8s0f1: pd 3 cq 4 qp 4 cm_id 0 mr 0 ctx 0 srq 2 Signed-off-by: Chiara Meiohas <cmeiohas@nvidia.com> Link: https://lore.kernel.org/r/2607bb3ddec3cae3443c2ea19e9f700825d20a98.1713268997.git.leon@kernel.org Signed-off-by: Leon Romanovsky <leon@kernel.org>
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
