STRUCT IDPF_QUEUE_ID_REG_CHUNK(9)

💅 struct idpf_queue_id_reg_chunk(9) 🎀

okay bestie, welcome to the Kernel API Manual — yes that's the manual name, and yes this page is a whole mood. it's a struct page, it's short, it's iconic, let's go ✨

---

🌸 NAME 🌸

struct idpf_queue_id_reg_chunk — the individual queue ID and register chunk situation. one chunk, one queue ID range, one register offset. it's giving "small struct, big responsibilities" 💅

---

✨ SYNOPSIS ✨

struct idpf_queue_id_reg_chunk {
    u64 qtail_reg_start;
    u32 qtail_reg_spacing;
    u32 type;
    u32 start_queue_id;
    u32 num_queues;
 };

that's the whole thing, no cap. five members and a dream 🫶

---

🦋 Members 🦋

so every field is a little main character in its own right, let me introduce them properly:

• qtail_reg_start — the queue tail register offset. this is where the register stuff starts. the starting point. the origin story 💫
• qtail_reg_spacing — the queue tail register spacing. like, how far apart the registers sit from each other. personal space matters, fr fr ✨
• type — the queue type of the queues in this chunk. what kind of queue are we even talking about. vibe check energy 🔥
• start_queue_id — the starting queue ID in the chunk. where this chunk's queue numbering kicks off, no questions asked 🎀
• num_queues — the number of queues in the chunk. literally just counting. how many are in the group chat 💀

side note bestie: all five members are described in the original with exactly those one-liners, so nothing's missing, nothing's extra. we keep the facts, we just serve them with flavor 💖

💜 sign-off 💜

this little beauty comes to you from ./drivers/net/ethernet/intel/idpf, dated October 2026, and it's filed under struct idpf_...id_reg_chunk(9). that's the header at the top and the footer at the bottom, all accounted for 🍓

slay, go read your kernel headers, ily, bye 👑⭐
