OpenCL driver issue with Samsung Chromebook

Jim

Hi,

I had an issue with the OpenCL Driver on my Chomebook.

I followed ARM's instruction and successfully boot into Linux. However, I got an error message said that libxcb-dri2.so missing. After install libxcb-dri2.0-dev, I can compile Mali OpenCL SDK sample codes. But they won't be executed correctly under X11 or via fbdev. I past error message below. Any suggestion? Thanks.

> ./hello_world_opencl

OpenCL error: CL_OUT_OF_HOST_MEMORY

Creating an OpenCL context failed. common.cpp:248

    Thanks for sharing your information, krrishnarraj and Chris.

    Let me list my build environment to help us clarify the problem.

    I build the kernel under Linuxmint 15 xfce 64-bit with kernel v.3.8.0.32-generic on my host machine. AMD catalyst 13.8beta is installed. Since I am working on my Android app development, the essential packages for building Android are all installed on this machine.

    I am assuming that none of these installed packages should cause problems while building Mali driver.

    I manually applied the kernel patch by following the instruction from Mali website. I install the X11/Fbdev libraries under /opt/mali/{x11,fbdev}. And create a regular user account to build Mali OpenCL SDK samples. It reported that libxcb-dri2.so* missing in my case.

    Then, I installed the libxcb-dri-2.0-dev package, and recompiled the sample codes again. Now, the "OUT_OF_HOST_MEMORY" error show up.

    No clues for this in the meantime. I will try to start the whole progress again today to see if there is any difference.
