sti_hqvdp_update_hvsrc(9)

💅 sti_hqvdp_update_hvsrc(9) — it's giving kernel API manual energy 🎀

okay so bestie, we're in the Kernel API Manual today and this page is literally called sti_hqvdp_update_hvsrc(9). no cap, that's the whole name section — the original didn't give us a one-liner, so we're not inventing one. moving on ✨

---

🌸 SYNOPSIS 🌸

void sti_hqvdp_update_hvsrc (enum sti_hvsrc_orient orient , int scale ,
       struct sti_hqvdp_hvsrc *hvsrc );

that's the whole vibe. returns nothing, takes three things. let's meet them 🫶

---

🦋 ARGUMENTS 🦋

• orient — horizontal or vertical. that's it, that's the whole orientation choice, pick a lane bestie 💅
• scale — the scaling/zoom factor. how much we're zooming, basically 🔍
• hvsrc — the structure containing the LUT coef. yes, "coef" — that's how the original spells it, we don't fix, we respect 😌

---

✨ DESCRIPTION ✨

Update the Y and C Lut coef, as well as the shift param.

like — that's the job. Y and C LUT coefficients get updated, and the shift param comes along for the ride. both of them. together. iconic behavior honestly 👑

lowkey a short description but that's genuinely all the original gives us, so we're not out here making up extra lore 🙈

---

💀 RETURN 💀

None.

literally nothing. void. it's giving "i did the work and i don't need credit" main character energy 🌈
