1Amber Branch 2============ 3 4After Mesa 21.3, all non-Gallium DRI drivers were removed from the Mesa 5source-tree. These drivers are still being maintained to some degree, 6but only on the ``amber`` branch, and only for critical fixes. 7 8These drivers include: 9 10- Radeon 11- r200 12- i915 13- i965 14- Nouveau (the DRI driver for NV04-NV20) 15 16At the same time, the OpenSWR Gallium driver was removed from the Mesa 17source-tree, because it was already practically speaking unmaintained and 18the actively maintained LLVMpipe offers much of the same functionality. 19 20Users with Intel GPUs that were using i965 should migrate to either Iris 21or Crocus, depending on their GPU. These drivers generally speaking both 22perform better and have more features than i965 had, and due to sharing 23more code with the rest of the Mesa infrastructure, gets more bug fixes 24and features. 25 26Similarly, users of i915 should migrate to i915g (the Gallium driver for 27the same hardware), as it's still being maintained. 28 29Users who depend on the removed drivers will have to use them built from 30the Amber branch in order to get updates. 31 32Building 33-------- 34 35The Amber branch has some extra logic to be able to coexist with recent 36Mesa releases without them stepping on each others toes. In order to 37enable that logic, you need to pass the ``-Damber=true`` flag to Meson. 38 39Documentation 40------------- 41 42On `docs.mesa3d.org <https://docs.mesa3d.org/>`__, we currently only 43publish the documentation from our main branch. But you can view the 44documentation for the Amber branch `here 45<https://gitlab.freedesktop.org/mesa/mesa/-/tree/amber/docs>`__. 46 47
