The feature is configured using a new general object: RDMA-Telemetry object, and depends on the following new caps: HCA_CAP.rdma_telemetry_notification_types and HCA_CAP.rdma_telemetry.

UID Permissions

Extended kernel lockdown permission set. The following sub-operations can now be called by tools (permission TOOLS_RESORCES) using new HCA capability bitmask field: tool_partial_cap.

The 5 sub-operations are:

  • QUERY_HCA_CAP with other function

  • QUERY_VUID with direct data

  • QUERY_ROCE_ADDRESS with other vport

  • SET_HCA_CAP with other function

  • POSTPONE_CONNECTED_QP_TIMEOUT with other vport

The new added caps are:

  • tool_partial_cap.postpone_conn_qp_timeout_other_vport,
