💅 sti_hqvdp_vtg_cb(9)

okay so bestie, welcome to the Kernel API Manual entry for sti_hqvdp_vtg_cb ✨ this one's a section 9 page, so it's kernel-internals territory — driver callback vibes only, no shell commands here 🫶

---

🌸 NAME 🌸

sti_hqvdp_vtg_cb — literally the callback that handles the VTG Vsync event and displays the pending bottom field 💖 (yes, the original NAME line is just the function name with a lil dash, no big description — that's the whole name section, iykyk)

---

✨ SYNOPSIS ✨

int sti_hqvdp_vtg_cb (struct notifier_block *nb , unsigned long evt ,
       void *data );

so she takes a notifier block, an event, and some private data, and hands you back an int 💅 that's the whole signature, no cap.

---

🎀 ARGUMENTS 🎀

• nb — notifier block 🦋 (the notifier_block struct pointer, exactly as written)
• evt — event message ⭐
• data — private data 🔥

three args, three vibes, all accounted for 💜

🌈 DESCRIPTION 🌈

Handle VTG Vsync event, display pending bottom field 👑

that's it, that's the job — it's giving "when the VTG vsync shows up, show the pending bottom field." very main character energy for a display driver callback 😭✨

---

💀 RETURN 💀

0 on success. that's the only return value documented, so 0 it is, periodt 💅
