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.

Type	Availability	Supported hardware	driver	OS or software	can work with only free software?	missing parts to work with only free software	status / features
Display controller	Mainboards Standalone?	AST2500	ast	GNU/Linux	Yes	FSDG compliant distro for the AST2500 BMC

GPU	SOCs only?	Allwinner SOCs	Lima	GNU/Linux	Yes
GPU	SOCs only?	Allwinner SOCs	Mitgard / Utgard?	GNU/Linux	Yes
Display controller	? x86 Mainboards		xgi_z9s	Coreboot until 4.12	Yes
GPU Display controller	X86 computers only	Intel GPUs found in I945 and GM45 chipsets	gma	Coreboot	Yes
GPU Display controller	X86 computers only	Intel GPUs found in I945 and GM45 chipsets	i915	GNU/Linux when booting with Libreboot or Coreboot	Yes		Everything seem to work fine
Display controller	Some intel chipset / SOCs (Atom?)		gma500	GNU/Linux	No?	Needs to be supported by Libreboot or deblobbed Coreboot
Display controller	SOCs only	Several I.MX SOCs not supported by mxs-drm	imx-drm	GNU/Linux	Yes with I.MX <= I.MX6 Maybe with I.MX7 No for I.MX8 as it doesn't boot with free software yet
Display controller	SOCs only	Several I.MX SOCs not supported by imx-drm	mxs-drm	GNU/Linux	Yes with I.MX < I.MX6 like the I.MX28
Display controller	Many Amlogic SOCs	SOCs only	meson	GNU/Linux	No: doesn't boot with free software yet
