[PATCH 0/7] up-port of out-of-tree GSX GPU driver for r8a7796

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
