STRUCT IDPF_BUFQ_SET(9)

💖 struct idpf_bufq_set(9) 💖

okay so we're in the Kernel API Manual, and today's main character is struct idpf_bufq_set(9). She's a kernel struct, she has members, she has lore, and honestly? She's giving splitq-only energy. Let's get into it, bestie. 🫶

---

💖 NAME 💖

struct idpf_bufq_set — that's the name, no extra tagline, no subtitle. The manual keeps it mysterious. 💅

---

✨ SYNOPSIS ✨

here's her exact shape, no edits, no "fixing" the vibes:

struct idpf_bufq_set {
    struct idpf_buf_queue bufq;
    int num_refillqs;
    struct idpf_sw_queue *refillqs;
 };

---

🌸 Members 🌸

• bufq — the buffer queue. Literally the buffer queue, doing buffer-queue things. 💖
• num_refillqs — the number of refill queues. This is always equal to num_rxq_sets in idpf_rxq_group. No cap. ✨
• refillqs — pointer to the refill queues array. Pointer bestie, she points. 🎀

---

🦋 Description 🦋

🚨 Splitq only, bestie! 🚨

idpf_bufq_set associates a bufq to an array of refillqs. That's the whole assignment. 💅

In this bufq_set, there will be one refillq for each rxq in this rxq_group. One for each, matching set, cute little queue family. 🌸

Used buffers received by rxqs will be put on refillqs, which bufqs will clean to return new buffers back to hardware. The circle of buffer life, lowkey iconic. 🦋🔥

Buffers needed by some number of rxqs associated in this rxq_group are managed by at most two bufqs — and yes, that's depending on performance configuration. 👀
