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