Hi, Linux-libre only support 5 Radeon GPU families: - R600 - Evergreen - RV770 - Northern Islands - Southern Islands
However the Radeon driver supports much more GPUs. The following older GPU families need to be tested to understand if they work or not: - R100 - R200 - R300 - R400 - R500 - R700 And the following GPU families probably don't work at all: - C.Islands - V.Islands - A.Islands https://www.x.org/wiki/RadeonFeature and the Linux kernel source in drivers/gpu/drm/radeon has more information on the supported GPUs. In addition we have GPUs that are now supported by the amdgpu driver, and I didn't look into it yet. Once Linux-libre support is done, the next steps would be to make sure that Xorg and Wayland work fine with the driver. Sometimes you need some small tweaks to make it work. There is more information on all that here: https://libreplanet.org/wiki?title=Group:Hardware/research/gpu/radeon Given the status of the radeon and amdgpu drivers in linux-libre, did you already consider funding a project to add support for all AMD and Radeon GPUs to linux-libre? It would require to: - Find some funding (through NLnet, the FSF, crowdfunding through the FSF, etc). - Find someone to do it (I'm already way too busy with Replicant and personal issues). - Make sure that the people working on it have one or more desktop computers where it's possible to plug AMD/ATI GPUs, a keyboard and a display. - Buy or find 1 GPU for each family, in order to test the result. It can potentially be time consuming to find them second hand as depending on the location, availability can come and go. Denis.
