Grate driver

Grate-driver packages

Important

❗ The GRATE drivers are for older NVIDIA Tegra20/30/114 SoCs only! If you're looking for drivers for TK1/TX1, then you should use Nouveau drivers.

Build it yourself

General rules:

1. Use the master branches.
2. Install autotools and gcc.
3. Compile and install libdrm first.
4. Use the most recent mainline linux kernel or at least the most recent stable. You may also try the experimental grate kernel.
5. Update all libdrm opentegra mesa libvdpau-tegra at once as there could be interdependencies, start from libdrm.

Libdrm:

1. git clone https://github.com/grate-driver/libdrm.git
2. cd libdrm
3. sh autogen.sh --prefix=/usr --enable-tegra-experimental-api --disable-freedreno --disable-vmwgfx --disable-nouveau --disable-amdgpu --disable-radeon --disable-intel --disable-vc4
4. make install

Opentegra:

1. git clone https://github.com/grate-driver/xf86-video-opentegra.git
2. cd xf86-video-opentegra
3. sh autogen.sh --prefix=/usr
4. make install

Mesa:

1. git clone https://github.com/grate-driver/mesa.git
2. cd mesa
3. meson -Dprefix=/usr -Dgallium-drivers=grate -Ddri-drivers=swrast -Dplatforms=x11,drm -Dshared-glapi=true -Dgbm=true -Dglx=dri -Dosmesa=none -Dgles1=false -Dgles2=true -Degl=true -Dgallium-xa=false -Dgallium-vdpau=false -Dgallium-va=false -Dgallium-xvmc=false -Duse-elf-tls=false -Dgallium-nine=false -Db_ndebug=true -Dvulkan-drivers= -Dlibunwind=false -Dllvm=false build
4. cd build/
5. ninja && ninja install

1. for older Mesa versions only!
2. git clone https://github.com/grate-driver/mesa.git
3. cd mesa
4. sh autogen.sh --prefix=/usr --enable-dri --enable-glx --enable-shared-glapi --enable-texture-float --disable-nine --enable-debug --enable-dri3 --enable-egl --enable-gbm --enable-gles1 --enable-gles2 --enable-glx-tls --enable-valgrind=auto --enable-llvm-shared-libs --with-dri-drivers=swrast --with-gallium-drivers=swrast,grate --with-vulkan-drivers= --with-egl-platforms=x11,drm --disable-nine --disable-llvm --disable-omx-bellagio --disable-va --disable-vdpau --disable-xa --disable-xvmc --disable-gallium-osmesa --disable-libunwind
5. make install

Libvdpau-tegra:

1. git clone https://github.com/grate-driver/libvdpau-tegra.git
2. cd libvdpau-tegra
3. sh autogen.sh --prefix=/usr
4. make install
5. udevadm trigger
