EFADV_WR...ING_HINTS(3) EFA Direct Verbs Manual EFADV_WR...ING_HINTS(3)
efadv_wr_set_processing_hints - Set processing hints on the
current work request
#include <infiniband/efadv.h>
static inline void efadv_wr_set_processing_hints(
struct efadv_qp *efadv_qp,
uint32_t hints);
efadv_wr_set_processing_hints() sets processing hints on the
current work request being built. Hints allow the application to
communicate intended usage patterns to the device, which may use
them to optimize processing.
This function is a work request setter and 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.
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,
};
EFADV_WR_PROCESSING_HINT_BURST_PPS_SENSITIVE
Optimize for throughput in bursty, packet-rate sensitive
workloads.
