cg6_copyarea(9)

📦 version 7.3.1, in nixpkgs unstable

💅 cg6_copyarea — from the cg6_copyarea(9) kernel API manual, bestie

okay so picture this: you're deep in the kernel API manual (man 9 energy, section 9, very niche very iconic) and you stumble onto this little gem. it's called cg6_copyarea and honestly? it does exactly one thing and it does it slayfully. let's get into it 🎀

✨ SYNOPSIS ✨

void cg6_copyarea (struct fb_info *info , const struct fb_copyarea *area );

that's it. that's the whole signature. two args, returns nothing (void, she gives nothing and takes nothing 💅). copy it exactly, don't be cute with it.

🌸 ARGUMENTS 🌸

  • info — the frame buffer structure that represents a single frame buffer. like, one framebuffer per structure, that's her whole personality. 🦋
  • area — a struct fb_copyarea that hands over all the data needed to copy the framebuffer contents from one region to another. it's giving road map for pixels, fr fr. 🗺️

💖 DESCRIPTION 💖

so what does this drawing operation actually do? literally just this: it copies a rectangular area from one area of the screen to another area. that's the whole plot. rect goes in, rect comes out somewhere else. no cap, that's the entire vibe. ✨

like yeah bestie, it's a blit. it's the blit. region → region. screen → screen. obsessed. 🔥

and then go hang out with her friends, they all live in the same file:

they're a whole friend group honestly. 🫶

heads up: this page is filed under the kernel file ./drivers/video/fbdev/cg6.c — that's where the actual code is, this manpage is just the group chat recap. 🙈

okay that's the whole page!! u read it, u understood it, u ate. 🌈⭐ and for the credits moment — this little beauty comes from ./drivers/video/fbdev, dated October 2026, and it's cg6_copyarea(9) all day long. mwah 💋 🍓🧚💜
