write_qp_ctxts(9)

💅 write_qp_ctxts — kernel API manual, section 9

okay so bestie, welcome to the write_qp_ctxts(9) page 💖 this is the kernel API manual entry for it, and honestly? it's a little one. but it still ate, so let's get into it 🫶

---

🌸 NAME 🌸

write_qp_ctxts — write the qp ctxt to HW ✨

like literally that's the whole job. write the qp ctxt. to HW. no cap.

---

🎀 SYNOPSIS 🎀

int write_qp_ctxts (struct hinic_func_to_io *func_to_io , u16 base_qpn ,
u16 num_qps );

it's giving function signature realness 👑 returns an int, takes three args, we love a tidy little call 💅

---

🦋 ARGUMENTS 🦋

• func_to_io — the func to io channel that holds the IO components 🧚 this is the container, the main character, the thing that's got all the IO bits in it
• base_qpn — first qp number ⭐ literally the starting qp number, that's it, that's the vibe
• num_qps — number of qps to write 🌸 how many qps we're writing, bestie. the count. the amount. the quantity

---

💜 DESCRIPTION 💜

okay so the actual behaviour description is short and sweet and I respect it so much for that:

• Return 0 — Success 🎉
• negative — Failure 😭

that's it. that's the whole description. no extra lore, no bonus features, just: zero means slay, negative means it did not slay 💀

fr fr keep that in mind — a negative return is your failure signal, so vibe check your return value before you assume everything's iconic ✨
