This driver builds as a module against recent mainline kernels (6.0). It brings support for Mali Bifrost GPUs, based on the official ARM r8p0-01rel0 Linux driver.
Device tree bindings are already upstream for Mali Bifrost drivers.
You need a cross-compilation toolchain configured properly.
git clone https://github.com/bootlin/mali-bifrost.git
cd mali-bifrost
make -j4 KDIR=<linux-sources>
cp $(find -name mali_kbase.ko) <target-directory>
A Buildroot package (MALI_BIFROST_DRIVER) is available as well.
This driver exports a /dev/mali0 interface. Vendors usually provide
closed-source Mali libraries to interract with it. For instance,
Rockchip Mali libraries are also bundled in a Buildroot package
(ROCKCHIP_MALI).
