rdma_init_qp_attr(9)

📦 version 7.3.1, in nixpkgs unstable

🌸 rdma_init_qp_attr(9) 🌸

okay so welcome to the Kernel API Manual page for rdma_init_qp_attr(9) — yes bestie, the manual name is folded in right here instead of copy-pasting that header line. This is the function that initializes the QP attributes so you can transition to a specified QP state. It’s giving setup era, main character energy. 💅✨

💖 NAME 💖

rdma_init_qp_attr — initializes the QP attributes for use in transitioning to a specified QP state. That’s the whole assignment, no cap. 🦋

✨ SYNOPSIS ✨

int rdma_init_qp_attr (struct rdma_cm_id *id , struct ib_qp_attr
       *qp_attr , int *qp_attr_mask );

🎀 ARGUMENTS 🎀

  • id — the communication identifier associated with the QP attributes to initialize. It’s literally the ID card for this operation. 🪪
  • qp_attr — on input, this specifies the desired QP state. On output, the mandatory and desired optional attributes will be set in order to modify the QP to the specified state. The glow-up is bidirectional, bestie. ✨
  • qp_attr_mask — the QP attribute mask that may be used to transition the QP to the specified state. Mask on, slay on. 💅

🦋 DESCRIPTION 🦋

Okay, important: users must set qp_attr->qp_state to the desired QP state. Like, that is not optional — it’s the vibe check. 💅

Bestie, the qp_attr->qp_state thing is mandatory. This is not a drill. 🚨

This call will set all required attributes for the given transition, along with known optional attributes. So it’s doing the required homework and also the extra credit, highkey. 🎀

Users may override the attributes returned from this call before calling ib_modify_qp. So you can absolutely tweak the results before you commit, no cap. 🙈

Users that wish to have their QP automatically transitioned through its states can associate a QP with the rdma_cm_id by calling rdma_create_qp. That’s the auto-pilot route, iykyk. 🦋
