Subject: [PATCH iproute2-next v5 0/2] rdma: display resource limits in curr/max format
Date: Fri, 10 Jul 2026 09:17:57 +0800	[thread overview]
Message-ID: <20260710011759.378893-1-cui.tao@linux.dev> (raw)

From: Tao Cui <cuitao@kylinos.cn>

This series adds support for displaying RDMA device resource limits in
curr/max format in the rdma tool, building on the kernel uapi attribute
RDMA_NLDEV_ATTR_RES_SUMMARY_ENTRY_MAX which has landed in linux-next
(kernel commit 5911f6d6e7ce [1]).

Patch 1 syncs the rdma_netlink.h uapi header from the kernel.
Patch 2 updates the rdma tool to parse the new attribute and display
resource usage in curr/max format:

  $ rdma resource show
  0: mlx5_0: qp 123/131072  cq 45/65536  mr 200/1000000  pd 10/32768

Changes in v5:
- Split the rdma_netlink.h update into its own commit following the
  uapi headers sync format ("rdma: update uapi headers").
Changes in v4:
- Add a Link: reference to the kernel patch; re-send now that the
  kernel side has landed in linux-next.
