Hi! This is a set of patches to the out-of-tree driver for the PowerVR GX6650 GPU used in the R-Car M3-W SoC that is required to make it work on mainline.
The driver source can be downloaded here: https://www.renesas.com/en-us/solutions/automotive/rcar-demoboard.html The patched driver can also be found at https://github.com/uli/r8a7796-gpu The OpenCL tests and various others that are supplied with the "R-Car H3 Evaluation Software Package for Linux for Yocto v2.23.0" at https://www.renesas.com/en-us/solutions/automotive/rcar-opencl.html pass. Anything that relies on EGL, however, fails early with an error from eglInitialize(). I suspect this to be an incompatibility of the binary blob libraries with my user space and will look into it further. A description of the test setup and some test results can be found here: https://www.elinux.org/User:Uli/R-Car_M3-W_Mainline_GPU_Test This relies on the series "r8a7796 bits required for out-of-tree GSX module" for the DT and clock driver bits.
