drm_crtc_load_palette_8(9)

💖 drm_crtc_load_palette_8(9) 💖

okay so this is a page from the Kernel API Manual, bestie, and it's about drm_crtc_load_palette_8 — literally the little function that pushes a palette into your hardware for C8-ish formats. it's short, it's sweet, it ate, no notes 🎀

---

✨ SYNOPSIS ✨

void drm_crtc_load_palette_8 (struct drm_crtc *crtc , const struct
drm_color_lut *lut , drm_crtc_set_lut_func set_palette );

like, yes, that's the whole vibe. void return because it just does the thing and dips 💅

---

🌸 ARGUMENTS 🌸

• crtc — the CRTC that's doing the displaying, aka the main character of this whole situation 👑
• lut — the palette you want to program, your little color lineup 🎨
• set_palette — the callback that actually programs the hardware palette, the backstage crew making it happen 🫶

---

🦋 DESCRIPTION 🦋

so what it does is: it programs the palette you passed in lut into the hardware. that's it. that's the function. iconic behavior honestly ✨

⚠️ but listen — the input palette must have 256 entries per color component. not 255, not "eh somewhere around there". 256. per. component. the vibe check is strict on this one, fr fr 😭
