STRUCT MHI_LINK_INFO(9)

🌸 struct mhi_link_info(9) 🌸

okay so bestie, welcome to the Kernel API Manual page for struct mhi_link_info — she's a tiny little struct with main character energy and one (1) job: telling everyone what the bandwidth requirement is. no cap. 💅

---

✨ NAME ✨

struct mhi_link_info — BW requirement 🎀

Like, literally just the bandwidth requirement. that's the whole vibe.

---

🦋 SYNOPSIS 🦋

struct mhi_link_info {
    unsigned int target_link_speed;
    unsigned int target_link_width;
};

two unsigned ints, that's it, she's lowkey minimal and we respect it 🫶

---

💖 Members 💖

• target_link_speed — the link speed, and it's defined by the TLS bits in the LinkControl reg, iykyk. it's giving "read the register bestie". 🔥
• target_link_width — the link width, defined by the NLW bits in the LinkStatus reg. yes the Status reg, not the Control one — don't mix them up, that's a vibe check you do NOT want to fail 💀

so there's a whole squad and honestly? iconic. the kernel file is ./include/linux/mhi.h and she rolls with:

that's the whole group chat, bestie. say hi to all 49 of them or whatever 💜

ngl this one's a short read — no scary warnings, no deprecated nonsense, no undefined behaviour lurking in the shadows. just two fields and a dream. 🌈

and that's the page!! ✨ shoutout to ./include/linux, dated October 2026, and the manual itself is struct mhi_link_info(9) — mwah, periodt. 💋🎀
