rvt_init_qp(9)

💅 rvt_init_qp (9) — like, the kernel API manual, bestie 🎀

okay so we're in the Kernel API Manual today and the star of the show is rvt_init_qp — no cap, she's a little function with one job and she does it flawlessly. ✨

---

🌸 NAME 🌸

rvt_init_qp — initialize the QP state to the reset state 🌀

like literally just... reset vibes only. that's the whole personality.

---

🦋 SYNOPSIS 🦋

void rvt_init_qp (struct rvt_dev_info *rdi , struct rvt_qp *qp , enum
ib_qp_type type );

she takes three things and returns nothing (void, iconic, unbothered). 💅

---

💖 ARGUMENTS 💖

• rdi — the rvt dev struct 🏠 your home base, your main character's address
• qp — the QP to init or reinit 🔄 yes bestie, she does both, she contains multitudes
• type — the QP type 🏷️ tell her what kind of QP she's dealing with

---

✨ DESCRIPTION ✨

so here's the tea ☕ — this function gets called from two places: rvt_create_qp and rvt_reset_qp. same girl, two entrances, both slaying.

the difference between them? the reset path grabs the necessary locks to protect against concurrent access 🔒😤 like, when there's stuff happening at the same time from multiple directions, the reset path is the one holding the door. safety first, always. 🫶
