Introductions

The status of support of GPUs not only depend on the GPU vendor and family but in some case also on if there are free replacements for the video BIOS or equivalent.

Fully free software status

This page summarize the research on which GPU and display controllers can work with fully free software.

Many SOCs have a display controller that work fine and doesn't need a GPU. That enables to use various displays without necessarily needing to support the GPU. When the GPU is unsupported you typically don't have 3D acceleration.

GPUs	driver	OS or software	can work with only free software?	missing parts to work with only free software	status / features
AST2500	?	GNU/Linux	Yes		No 3D acceleration
Many Nvidia GPUs	nouveau	GNU/Linux	No	Bytecode found in the video BIOS
Many ATI and AMD GPUs	Radeon	GNU/Linux	No	Bytecode found in the video BIOS
Lemote ATI Radeon GPU		GRUB	Yes
Many older ATI/AMD GPUs	RadeonHD	GNU/Linux	Yes?	nonfree firmware to remove?
	Etnaviv	GNU/Linux	Yes
	Lima	Yes
	xgi_z9s	Coreboot until 4.12	Yes	No 3D acceleration in Coreboot
Intel GPUs found in I945 and GM45 chipsets	gma	Coreboot	Yes	No 3D acceleration in Coreboot
Intel GPUs found in I945 and GM45 chipsets	i915	GNU/Linux when booting with Libreboot or Coreboot	Yes		Everything seem to work fine
