💖 NAME 💖

rte_hash_rcu_config — bestie, this is the struct that holds all your RCU QSBR config for a hash table. It's from the DPDK Library Functions Manual, and no cap, it's basically the glow-up settings page for your hash table's RCU behavior. 🦋

✨ SYNOPSIS ✨

#include <rte_hash.h>

🎀 Data Fields

  • struct rte_rcu_qsbr * v
  • enum rte_hash_qsbr_mode mode
  • uint32_t dq_size
  • uint32_t trigger_reclaim_limit
  • uint32_t max_reclaim_size
  • void * key_data_ptr
  • rte_hash_free_key_data free_key_data_func

🌸 Detailed Description 🌸

It's giving "HASH RCU QSBR configuration structure." That's the whole vibe — you fill this baby in, hand it over, and the hash table knows how to do its RCU QSBR thing. 💅

👑 Field Documentation 👑

🌈 struct rte_rcu_qsbr* v

The RCU QSBR variable, queen. This is the actual one. ✨

Definition at line 103 of file rte_hash.h.

🦋 enum rte_hash_qsbr_mode mode

Mode of RCU QSBR. It's RTE_HASH_QSBR_MODE_xxx, and '0' is the default — which means create defer queue for reclaim. Slay. 💖

Definition at line 104 of file rte_hash.h.

🍓 uint32_t dq_size

RCU defer queue size. Default is literally just the total hash table entries — it matches your table, periodt. 🎀

Definition at line 108 of file rte_hash.h.

⭐ uint32_t trigger_reclaim_limit

The threshold that triggers auto reclaim. Hit this number and the reclaiming just starts happening on its own. Main character energy fr. 🔥

Definition at line 112 of file rte_hash.h.

💜 uint32_t max_reclaim_size

Max entries to reclaim in one go. Default is RTE_HASH_RCU_DQ_RECLAIM_MAX. Don't overthink it, just know it's a cap on the reclaim batch. 😭

Definition at line 113 of file rte_hash.h.

🧚 void* key_data_ptr

Pointer passed to the free function. Typically, this is the pointer to the data structure to which the resource to free (key-data) belongs. And bestie, this one can be NULL — no pressure, she's flexible. 🫶

Definition at line 117 of file rte_hash.h.

🎀 rte_hash_free_key_data free_key_data_func

Function to call to free the resource (key-data). You bring the cleanup logic, she'll call it. Iykyk. 💅
