🦋 machfb(4) — ATI Mach64/RAGE framebuffer driver 🦋

okay bestie, welcome to the MACHFB(4) / machfb(4) page from the Kernel Interfaces Manual 💖 this is literally the whole vibe: ATI Mach64/RAGE framebuffer driver, explained with maximum group-chat energy and zero lost details, no cap.

🌸 NAME 🌸

machfb — the ATI Mach64/RAGE framebuffer driver. That's the whole name check, bestie: one driver, ATI Mach64/RAGE framebuffer behavior, iconic. 💅

✨ SYNOPSIS ✨

Here's the config energy, exactly as it is:

machfb* at pci?
wsdisplay* at machfb?

🎀 DESCRIPTION 🎀

The machfb driver provides support for ATI RAGE and Mach64 graphics accelerators. 2D acceleration is supported via the rasops(9) framework — yes, that's the framework doing the 2D acceleration thing, and yes, it's a whole moment 🫶.

machfb is primarily used on PowerPC and SPARC64, but it works on other architectures. By default, on other architectures, vga(4) or genfb(4) will be used instead. Important detail, bestie: on those other architectures, the default is not machfb — it's vga(4) or genfb(4). Not me being dramatic, that's just the actual default situation 💀✨.

🔥 HARDWARE 🔥

The following chipsets should work:

  • ATI RAGE II
  • ATI RAGE IIc
  • ATI RAGE Pro
  • ATI RAGE LT
  • ATI RAGE LT Pro
  • ATI RAGE XL
  • ATI Mach64 GX
  • ATI Mach64 CX
  • ATI Mach64 CT
  • ATI Mach64 VT

That's the list, periodt — no invented chipsets, no guessing, just the exact hardware tea 🍓.

⭐ HISTORY ⭐

The machfb driver first appeared in NetBSD 2.0. That's the origin story, bestie 🎀✨.

okay that's the whole machfb(4) page! mwah 💋 this one's source/version sticker says Debian, and the date on it is April 14, 2025 — xoxo, your Unix bestie 💅🫶
