VGAFB(4)

💅 VGAFB(4) — VGA frame buffer, but make it cute

okay bestie, pull up a chair because we're talking about vgafb — the VGA frame buffer, and honestly? it's giving quiet luxury. she's a Kernel Interfaces Manual girlie and she does exactly what she says on the tin 🎀

---

✨ SYNOPSIS ✨

# sparc64, macppc
vgafb* at pci?
wsdisplay* at vgafb?

like, that's the whole vibe. she attaches at pci? on sparc64 and macppc, and then wsdisplay* attaches at vgafb? — chain of command, main character energy only 👑

---

🌸 DESCRIPTION 🌸

so what is vgafb? she's a memory based color frame buffer driver for the wscons(4) console framework, and she ate. literally no notes. 🦋

here's the thing though — she does not provide direct device driver entry points. nope, not her job, not her era. instead she makes her functions available via the internal wsdisplay(4) interface. iykyk 💅

and the way she serves both:

• unaccelerated access — as a dumb framebuffer, no thoughts head empty, and honestly relatable
• accelerated access methods — when she wants to be fancy

both of those are provided to wscons(4). versatile queen 🌈✨
