💅 rivafb_fillrect(9) — the kernel API manual, bestie edition 🎀

okay so this is rivafb_fillrect, straight out of the rivafb corner of the kernel API manual, and it's genuinely one of the most satisfying little functions ever. it fills stuff with color. hardware-accelerated color. are we obsessed? yes.

✨ NAME ✨

rivafb_fillrect — hardware accelerated color fill function 🔥

like, it paints a whole region of your framebuffer in one solid color, and the hardware does the heavy lifting. no cap.

---

✨ SYNOPSIS ✨

void rivafb_fillrect (struct fb_info *info , const struct fb_fillrect
*rect );

that's the whole signature, keep it exactly like that 🫶

---

✨ ARGUMENTS ✨

• info — a pointer to the fb_info structure. yes, that fb_info, the big one, the main character 📋
• rect — a pointer to the fb_fillrect structure. this one is const, meaning don't you dare touch it 🙈

---

✨ DESCRIPTION ✨

so here's the vibe: this function fills up a region of framebuffer memory with a solid color, and it gives you a choice of two different ROP's — either copy or invert. that's it, that's the whole gig. iconic behavior, honestly 💖

CALLED FROM: framebuffer hook 🌸

ngl, "framebuffer hook" is literally the whole labeling here — that's where this thing gets invoked, iykyk.
