OpenCL on Samsung Chromebook Mali-T604 (Chrubuntu OR ChromeOS)

Question: How to get OpenCL drivers installed on either Chrubuntu or ChromeOS?

Background: I am able to successfully compile and execute OpenCL code  (using Chrubuntu on sdcard + Mali SDK + Code::Blocks) but every  example/sample and simple 'hello, world' app returns an error when using  clGetPlatformIDs. The code compiles and runs just fine, but I'm not  getting a CL_SUCCESS so I am thinking this must mean there is no proper  driver.

For example,

cl_int err;
cl_platform_is platform_id = NULL;
err = clGetPlatformIDs(1,&platform_id,NULL);

returns 2123707424

Any help is appreciated.

Thanks,

Todd Thompson

    Hi Todd,

    I guess it depends where your userspace libraries came from. The hardware is essentially the same chipset as the Samsung Arndale developer board.

    so it is in theory capable of running GPU compute jobs on the Mali-T604 but as you may be finding, unless the OS was built with GPU compute support both in userspace and kernel space then it's not guaranteed you can access the GPU compute hardware.

    The only platform I can think of which is intended to support OpenCL at the moment is the Arndale board running Linux.

    HTH, Pete

    Pete,

    It looks like bearon @ beyond3d forum (http://forum.beyond3...ead.php?t=63071) has found OpenCL drivers for Nexus 10.

    It's created a lot of excitement (http://www.anandtech...exus-10-devices) but I don't know if I can leverage this for Samsung Chromebook.

    I'm not a compiler engineer and I'm just learning OpenCL so I'm hoping this finding will either provide direct support or lead the way for ARM+Google+Samsung to provide the necessary drivers for ChromeOS and/or Chrubuntu.

    It makes the mobility of the Chromebook very appealing if development, testing and debugging is available on one platform.  I need to compile and test prior to execution on very large distributed+parallel systems.

    Thanks for reply,

    I do not understand why this device is promoted as a developer device, it seems there is no will to release any drivers supporting such a claim!.

    Very disappointing.

    Very disappointing indeed.
