Hi, did some more research. Is the following correct? -OpenCL is not yet supported for Intel GPU on Linux -i915 driver can be accessed by opening /sys/devices/pci/0000:00:02.0/device and ioctling it? Next I have to learn about output from GPU. In some docs I could read direct access to the graphics aperture from CPU is blocked by the hardware. I guess the output of GPU EUs must end up in the framebuffer. I need to learn how to create and read framebuffer devices. BR,
