rte_mempool_ops_table(3)

💖 rte_mempool_ops_table(3) 💖

okay bestie, so this is a page straight out of the Library Functions Manual, and the star of the show is rte_mempool_ops_table. it's a struct. it's iconic. it's lowkey holding the whole mempool ops situation together. let's get into it 🫶

✨ NAME ✨

rte_mempool_ops_table — the vibes are structural, the details are below ✨

---

🌸 SYNOPSIS 🌸

#include <rte_mempool.h>

🎀 Data Fields 🎀

• rte_spinlock_t sl
• uint32_t num_ops
• struct rte_mempool_ops ops [RTE_MEMPOOL_MAX_OPS_IDX]

---

👑 Detailed Description 👑

so. this is the structure that stores the table of registered ops structs, and each one of those bad boys contains the function pointers for the mempool ops functions. no cap 💅

the way that each process has its own storage for this ops struct array so that the mempools can be shared across primary and secondary processes?? obsessed. literally the whole point.

the indices used to access the array are valid across processes 🦋 — whereas any function pointers stored directly in the mempool struct would not be. which is why we end up simply having "ops_index" in the mempool struct. it's giving clean architecture. it's giving main character energy. periodt ✨

💜 rte_spinlock_t sl

Spinlock for add/delete. that's it, that's the job 💅

🍓 uint32_t num_ops

Number of used ops structs in the table. like a little counter for how many slots are actually taken 🌸

---

🧚 struct rte_mempool_ops ops[RTE_MEMPOOL_MAX_OPS_IDX]

Storage for all possible ops structs. every single one. the whole roster 🔥
