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	Supported hardware	driver	OS or software	can work with only free software?	missing parts to work with only free software	status / features
Display controller	AST2500	ast	GNU/Linux	Yes	FSDG compliant distro for the AST2500 BMC
GPU Display controller	Many Nvidia GPUs	nouveau	GNU/Linux	No	Bytecode found in the video BIOS
GPU Display controller	Many ATI and AMD GPUs	Radeon	GNU/Linux	No	Bytecode found in the video BIOS
GPU Display controller	Many ATI and AMD GPUs	amdgpu	GNU/Linux	No	Bytecode found in the video BIOS
GPU Display controller	Lemote ATI Radeon GPU		GRUB	Yes
GPU Display controller	Many older ATI/AMD GPUs	RadeonHD	GNU/Linux	Yes?	nonfree firmware to remove?	No 3D acceleration without nonfree firmwares
GPU		Etnaviv	GNU/Linux	Yes
GPU		Lima	Yes
		xgi_z9s	Coreboot until 4.12	Yes	No 3D acceleration in Coreboot
GPU Display controller	Intel GPUs found in I945 and GM45 chipsets	gma	Coreboot	Yes	No 3D acceleration in Coreboot
GPU Display controller	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		gma500	?
Display controller	Several I.MX SOCs	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	Several I.MX SOCs	mxs-drm	GNU/Linux	Yes with I.MX < I.MX6 like the I.MX28
Display controller		meson	GNU/Linux	No: doesn't boot with free software yet
Display controller		msm	GNU/Linux	Doesn't boot with free software yet?
Display controller Some limited 2D acceleration?	Many OMAP SOCs	omapdrm	GNU/Linux	Yes, at least for: OMAP3 OMAP4
Display controller		rockchip	GNU/Linux	?
Display controller	Many Allwinner SOCs	sun4i-drm	GNU/Linux	Yes
GPU Display controller	Many broadcom SOCs	vc4	GNU/Linux	No: GPU not initialized by free software boot
GPU	Several SOCs	adreno	GNU/Linux	Unknown (needs testing with linux-libre)	Are the nonfree firmwares really required?
