sti_hqvdp_get_next_cmd(9)

💅 sti_hqvdp_get_next_cmd — the kernel API manual page, bestie edition ✨

okay so first things first: this is sti_hqvdp_get_next_cmd, and it lives in the Kernel API Manual. The official NAME line is literally just sti_hqvdp_get_next_cmd - and then... nothing. A whole dash with no vibes after it. The description slot is empty. Iconic of it, honestly. We move on 🎀

---

✨ SYNOPSIS ✨

int sti_hqvdp_get_next_cmd (struct sti_hqvdp *hqvdp );

that's it. that's the whole signature. one function, one pointer, one int coming back at you 🫶

---

🌸 ARGUMENTS 🌸

• hqvdp — the hqvdp structure. that's the whole description. the hqvdp structure is a structure, and it is called hqvdp. we are SO back. take it, pass it, love it 💖

---

🦋 DESCRIPTION 🦋

so what does it actually do? it looks for the next hqvdp_cmd that will be used by the FW. that's the FW, the firmware, not a casual abbreviation, okay 😌

that's the mission. that's the whole mission. find the next command that the firmware's gonna reach for, and report back. lowkey simple, highkey essential 💅

---

🔥 RETURN 🔥

what you get back depends, so pay attention bestie:

• the offset of the next command that will be used — that's your happy path, slay ✨
• -1 — in error cases. so if you see -1, something went sideways. not a vibe, but at least you know fr fr 💀
