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. 10 11PanVK, the Vulkan implementation in the Panfrost driver stack, is currently 12**non-conformant** on all GPUs. 13 14The following hardware is currently supported: 15 16+--------------------+---------------+-----------+--------+--------+ 17| Models | Architecture | OpenGL ES | OpenGL | Vulkan | 18+====================+===============+===========+========+========+ 19| T600, T620, T720 | Midgard (v4) | 2.0 | 2.1 | | 20+--------------------+---------------+-----------+--------+--------+ 21| T760, T820, T830 | Midgard (v5) | 3.1 | 3.1 | | 22| T860, T880 | | | | | 23+--------------------+---------------+-----------+--------+--------+ 24| G72 | Bifrost (v6) | 3.1 | 3.1 | 1.0 | 25+--------------------+---------------+-----------+--------+--------+ 26| G31, G51, G52, G76 | Bifrost (v7) | 3.1 | 3.1 | 1.0 | 27+--------------------+---------------+-----------+--------+--------+ 28| G57 | Valhall (v9) | 3.1 | 3.1 | | 29+--------------------+---------------+-----------+--------+--------+ 30| G310, G610 | Valhall (v10) | 3.1 | 3.1 | 1.0 | 31+--------------------+---------------+-----------+--------+--------+ 32 33Other Midgard and Bifrost chips (e.g. G71) are not yet supported. 34 35Older Mali chips based on the Utgard architecture (Mali-400, Mali-450) are 36supported in the :doc:`Lima <lima>` driver, not Panfrost. Lima is also 37available in Mesa. 38 39Other graphics APIs (OpenCL) are not supported at this time. 40 41Building 42-------- 43 44Panfrost's OpenGL support is a Gallium driver. Since Mali GPUs are 3D-only and 45do not include a display controller, Mesa uses kmsro to support display 46controllers paired with Mali GPUs. If your board with a Panfrost supported GPU 47has a display controller with mainline Linux support not supported by kmsro, 48it's easy to add support, see the commit ``cff7de4bb597e9`` as an example. 49 50LLVM is *not* required by Panfrost's compilers. LLVM support in Mesa can 51safely be disabled for most OpenGL ES users with Panfrost. 52 53Build like ``meson . build/ -Dvulkan-drivers=panfrost 54-Dgallium-drivers=panfrost -Dllvm=disabled`` for a build directory 55``build``. 56 57For general information on building Mesa, read :doc:`the install documentation 58<../install>`. 59 60Chat 61---- 62 63Panfrost developers and users hang out on IRC at ``#panfrost`` on OFTC.
