1Panfrost 2======== 3 4The Panfrost driver stack includes an OpenGL ES implementation for Arm Mali 5GPUs based on the Midgard and Bifrost microarchitectures. It is **conformant** 6on `Mali-G52 <https://www.khronos.org/conformance/adopters/conformant-products/opengles#submission_949>`_, 7`Mali-G57 <https://www.khronos.org/conformance/adopters/conformant-products/opengles#submission_980>`_ 8and `Mali-G610 <https://www.khronos.org/conformance/adopters/conformant-products/opengles#submission_1053>`_, 9but **non-conformant** on other GPUs. The following hardware is currently 10supported: 11 12+--------------------+---------------+-----------+--------+ 13| Models | Architecture | OpenGL ES | OpenGL | 14+====================+===============+===========+========+ 15| T600, T620, T720 | Midgard (v4) | 2.0 | 2.1 | 16+--------------------+---------------+-----------+--------+ 17| T760, T820, T830 | Midgard (v5) | 3.1 | 3.1 | 18| T860, T880 | | | | 19+--------------------+---------------+-----------+--------+ 20| G72 | Bifrost (v6) | 3.1 | 3.1 | 21+--------------------+---------------+-----------+--------+ 22| G31, G51, G52, G76 | Bifrost (v7) | 3.1 | 3.1 | 23+--------------------+---------------+-----------+--------+ 24| G57 | Valhall (v9) | 3.1 | 3.1 | 25+--------------------+---------------+-----------+--------+ 26| G310, G610 | Valhall (v10) | 3.1 | 3.1 | 27+--------------------+---------------+-----------+--------+ 28 29Other Midgard and Bifrost chips (e.g. G71) are not yet supported. 30 31Older Mali chips based on the Utgard architecture (Mali-400, Mali-450) are 32supported in the :doc:`Lima <lima>` driver, not Panfrost. Lima is also 33available in Mesa. 34 35Other graphics APIs (Vulkan, OpenCL) are not supported at this time. 36 37Building 38-------- 39 40Panfrost's OpenGL support is a Gallium driver. Since Mali GPUs are 3D-only and 41do not include a display controller, Mesa uses kmsro to support display 42controllers paired with Mali GPUs. If your board with a Panfrost supported GPU 43has a display controller with mainline Linux support not supported by kmsro, 44it's easy to add support, see the commit ``cff7de4bb597e9`` as an example. 45 46LLVM is *not* required by Panfrost's compilers. LLVM support in Mesa can 47safely be disabled for most OpenGL ES users with Panfrost. 48 49Build like ``meson . build/ -Dvulkan-drivers= 50-Dgallium-drivers=panfrost -Dllvm=disabled`` for a build directory 51``build``. 52 53For general information on building Mesa, read :doc:`the install documentation 54<../install>`. 55 56Chat 57---- 58 59Panfrost developers and users hang out on IRC at ``#panfrost`` on OFTC.
