EFADV_WR_S...SSING_HINTS(3)

🌸 NAME 🌸

okay so bestie, welcome to the EFA Direct Verbs Manual ✨ — this page is all about efadv_wr_set_processing_hints, which sets processing hints on the current work request 💅

✨ SYNOPSIS ✨

#include <infiniband/efadv.h>

static inline void efadv_wr_set_processing_hints(
    struct efadv_qp *efadv_qp,
    uint32_t hints);

💖 DESCRIPTION 💖

efadv_wr_set_processing_hints() sets processing hints on the current work request being built. Hints let the application communicate intended usage patterns to the device, and the device may use them to optimize processing. iconic behavior, honestly 🦋

This function is a work request setter, so the timing is lowkey everything: it must be called after the work request opcode function (e.g. ibv_wr_send()) and before ibv_wr_complete() or the next work request opcode call. no cap 😭

Use efadv_qp_from_ibv_qp_ex() to get the efadv_qp for accessing this interface 🫶

The QP must be created with EFADV_WR_EX_WITH_PROCESSING_HINTS set in efadv_qp_init_attr.wr_flags to use this function 💀

The hints argument is a bitmask of efadv_wr_processing_hint values:

enum efadv_wr_processing_hint {
    EFADV_WR_PROCESSING_HINT_BURST_PPS_SENSITIVE = 1 << 0,
};
