rte_mempool_cache(3)

📦 version 26.03, in nixos 26.05, nixpkgs unstable

💅 rte_mempool_cache 💅

okay bestie, so this is a page from the Library Functions Manual for rte_mempool_cache — yes that's the whole name, it's giving very "the function IS the title" energy and honestly? iconic. it's a DPDK thing, and we're gonna get through it together 🫶

✨ NAME ✨

rte_mempool_cache — that's it, that's the name, no cap 💖

✨ SYNOPSIS ✨

#include <rte_mempool.h>

like, that's the whole include. one line. she's low maintenance 💅

🎀 Data Fields 🎀

here's the squad, in order, exactly as she lists them:

  • uint32_t size
  • uint32_t flushthresh
  • uint32_t len
  • void * objs [RTE_MEMPOOL_CACHE_MAX_SIZE *2]

🌸 Detailed Description 🌸

so what IS this? it's a structure that stores a per-core object cache. literally that's the vibe: each core gets its own lil stash of objects. main character energy per core, fr fr 👑

Definition at line 90 of file rte_mempool.h. (not me being specific about line numbers, but the facts stay ✨)

🦋 Field Documentation 🦋

💜 uint32_t size

Size of the cache — how big she is. that's the whole description and honestly she ate.

Definition at line 91 of file rte_mempool.h.

💜 uint32_t flushthresh

Threshold before we flush excess elements — the point where the excess gets yeeted out. the limit. the "okay that's enough" line 😭

Definition at line 92 of file rte_mempool.h.

💜 uint32_t len

Current cache count — how many are in there right now. the live count, the current situation, the vibes check 💀

Definition at line 93 of file rte_mempool.h.

💜 void* objs[RTE_MEMPOOL_CACHE_MAX_SIZE *2]

Cache objects — the actual objects, bestie. 🍓

and here's the important bit, so listen up: the cache is allocated to this size to allow it to overflow in certain cases to avoid needless emptying of cache. so she's deliberately extra-sized so she can spill over a little instead of doing a whole wasteful empty every time. it's giving "always be prepared" and i respect it 🌈

and that's the page!! no notes, no flags, no env vars, no exit statuses — just a cute lil struct with four fields and a whole lotta purpose 🧚

okay and for the sign-off: this whole thing is from the DPDK manual, Version 26.03.0, and the page is rte_mempool_cache(3). that's the tea, periodt 💅🎀
