💖 hfi1_alloc_ctxt_rcv_groups(9) 💖

okay so bestie, we're in the Kernel API Manual today and this one is a whole little kernel function that literally sets up the expected receive groups. yes it's giving driver-internals, but stay with me, it's actually so clean 🎀

---

✨ NAME ✨

hfi1_alloc_ctxt_rcv_groups — initialize expected receive groups 🫶

like, it's the function whose entire job is booting up the groupings for expected receives. no cap.

---

🌸 SYNOPSIS 🌸

int hfi1_alloc_ctxt_rcv_groups (struct hfi1_ctxtdata *rcd );

it hands you back an int, and it takes exactly one thing. iconic minimalism honestly 👑

---

🦋 ARGUMENTS 🦋

• rcd — the context to add the groupings to. that's it, that's the whole argument 💅 it's your struct hfi1_ctxtdata * and it's the lucky context getting the new groupings added onto it.
