tvout_prefo...r_set_matrix(9)

💅 NAME 💅

tvout_preformatter_set_matrix — okay so this one sets the preformatter matrix, bestie. That's literally the whole job. No cap.

---

✨ SYNOPSIS ✨

void tvout_preformatter_set_matrix (struct sti_tvout *tvout , struct
drm_display_mode *mode );

Notice the return type? It's void. It gives you nothing back, and honestly? Iconic. It just does the thing and leaves. 🫶

---

🎀 ARGUMENTS 🎀

• tvout — the tvout structure itself, your main character of the hour 👑
• mode — the display mode structure, aka the vibe spec for what's getting displayed 🌸

That's it. Two arguments. Two besties. Periodt.

Okay that's the whole page, mwah 💖 This gem lives under ./drivers/gpu/drm/sti, it's dated October 2026, and it goes by the very dramatic name of tvout_prefo...r_set_matrix(9) — yes the ellipsis is part of the branding, we don't question it. Slay the kernel, bestie ✨🌈
