dpaa2_sg_set_bpid(9)

💅 dpaa2_sg_set_bpid(9) — like, the Kernel API Manual page, bestie

okay so real talk: this is a page straight outta the Kernel API Manual, and it's honestly smol but iconic. we're setting one single field in a scatter-gather entry. that's it. that's the whole vibe. and yet?? it matters. periodt.

✨ NAME ✨

dpaa2_sg_set_bpid — sets the buffer pool id in an SG entry 🎀

like, you hand it an SG entry, you hand it a bpid, and it puts that bpid in there. no cap.

---

🌸 SYNOPSIS 🌸

void dpaa2_sg_set_bpid (struct dpaa2_sg_entry *sg , u16 bpid );

the way this is literally a void function… she does her job and returns nothing, because she doesn't need to prove anything to anyone. main character energy fr fr. 💅

---

🦋 ARGUMENTS 🦋

• sg — the given scatter-gathering object 💖 (yes, this one, the one you're about to poke at, the SG entry itself)
• bpid — the bpid to be set ✨ (a u16, and it's the value that goes in — that's the whole assignment, iykyk)
