The Panfrost driver stack includes an OpenGL ES implementation for Arm Mali
|
|
|
|
|
GPUs based on the Midgard and Bifrost microarchitectures. It is **conformant**
|
|
|
|
|
on Mali G52 but **non-conformant** on other GPUs. The following hardware is
|
|
|
|
|
currently supported:

Panfrost's OpenGL support is a Gallium driver. Since Mali GPUs are 3D-only and
|
|
|
|
|
do not include a display controller, Mesa uses kmsro to support display
|
|
|
|
|
controllers paired with Mali GPUs. If your board with a Panfrost supported GPU
|
|
|
|
|
has a display controller with mainline Linux support not supported by kmsro,
|
|
|
|
|
it's easy to add support, see the commit ``cff7de4bb597e9`` as an example.

LLVM is *not* required by Panfrost's compilers. LLVM support in Mesa can
|
|
|
|
|
safely be disabled for most OpenGL ES users with Panfrost.

|
2021-08-12 16:05:26 +01:00
|
|
|
-Dgallium-drivers=panfrost -Dllvm=disabled`` for a build directory

``build``.
