STRUCT GSC_SCALER(9)

🌸 struct gsc_scaler(9) 🌸

okay bestie, gather round, because this is a page from the Kernel API Manual, section 9 — the kernel API one — and it's all about struct gsc_scaler. Think of it as the little vibe board that holds the configuration data for the G-Scaler inetrnal scaler 🫶 (yes, that's literally how the page spells "internal", and honestly? iconic. we respect the typo era 💅).

✨ NAME ✨

struct gsc_scaler — the configuration data for G-Scaler inetrnal scaler 🎀

---

🦋 SYNOPSIS 🦋

struct gsc_scaler {
    u32 pre_shfactor;
    u32 pre_hratio;
    u32 pre_vratio;
    u32 main_hratio;
    u32 main_vratio;
 };

that's the whole struct, no cap. five u32 fields, all in a row, all vibing ✨

---

💖 Members 💖

• pre_shfactor — pre sclaer shift factor 🌸 (the shift factor for the prescaler — and again, the page's spelling, not mine, we stan)
• pre_hratio — horizontal ratio of the prescaler 💫
• pre_vratio — vertical ratio of the prescaler 🌈
• main_hratio — the main scaler's horizontal ratio 🔥
• main_vratio — the main scaler's vertical ratio ⭐

so basically: prescaler gets a shift factor + an h-ratio + a v-ratio, and the main scaler gets its own h-ratio + v-ratio. two ratios for the prescaler, two for the main scaler, one shift factor, done. slay 🎯

ngl there's nothing dangerous on this page — it's a struct definition, the chillest kind of manpage. no undefined behaviour, no deprecation drama, just fields. main character energy but make it boring-safe 🧚

okay that's the page!! mwah 💋 this one came to you from the Kernel API Manual, section 9, source ./drivers/media/platform/samsu..., dated October 2026, and the footer was literally just struct gsc_scaler(9) again so we're bringing it full circle — bye bestie, go compile something 🦋💖✨
