okay bestie, welcome to FBDEVHW(4) — that's the page for fbdevhw, living in the Kernel Interfaces Manual section because it's down there in the kernel-adjacent trenches doing the real work 💅

🌸 NAME 🌸

fbdevhw — os-specific submodule for framebuffer device access

---

🦋 DESCRIPTION 🦋

so like. fbdevhw gives you functions for talking to a framebuffer device. that's the whole vibe. she's the translator bestie between you and the framebuffer 📺💬

she is os-specific — no cap, she only speaks for the OS she was built for.

she is also a submodule, which means she doesn't run the show solo. other video drivers use her. she's the supporting character who's lowkey carrying the whole plot 🙈✨

right now, a fbdevhw module is currently available for linux framebuffer devices. that's the one that exists atm, periodt.

okay so here's the relationship tea ☕ — fbdev(4) is a non-accelerated driver that runs on top of the fbdevhw module. she's riding on fbdevhw's shoulders, iconic.

but fbdevhw isn't exclusive to her, bestie! ✨ other drivers can use fbdevhw too, and when they do, it's usually switched on with this in the device section:

Option "UseFBDev"

that's the little handshake that says "yeah we're using fbdevhw now" 🫶
