STRUCT CHAIN_TRACKER(9)

💖 struct chain_tracker(9) 💖

okay so bestie, welcome to the Kernel API Manual entry for struct chain_tracker — yes it's a ✨firmware chain tracker✨ and yes it lives in the kernel, we love a lowkey legend 🫶

---

🌸 NAME 🌸

struct chain_tracker — firmware chain tracker. that's it, that's the vibe. short, sweet, iconic 👑

---

✨ SYNOPSIS ✨

struct chain_tracker {
    void *chain_buffer;
    dma_addr_t chain_buffer_dma;
 };

literally just two members. no cap, she's compact and she knows it 💅

---

🎀 Members 🎀

• chain_buffer — chain buffer. yep, that's the whole description. it's giving "confident and mysterious" 🙈
• chain_buffer_dma — physical address. that's the DMA address of the buffer, bestie, keep up 🦋

🦋 SEE ALSO 🦋

okay so there's a whole friend group here, and honestly? the way they all roll together is so cute. listen:

fr fr that's the entire squad and you will be clicking through every single one of them 🧚💜

pro tip from your girl: every literal detail above is exactly as it was in the original — no renaming, no merging, no invented options. we don't do that here 💀

and that's a wrap on our little kernel moment, bestie 🌈 this came out of ./drivers/scsi/mpt3sas, stamped October 2026, and it's the struct chain_tracker(9) page — go forth and slay your driver work ✨🎀💖
