OpenCL

Summary

This change will bring basic OpenCL support to Fedora to support the development of OpenCL enabled software and the development of OpenCL implementations itself. The change includes enabling Mesa's OpenCL state-tracker (in 10.0 with ICD support), packaging pocl - an CPU only OpenCL implementation - and the introduction of several other OpenCL related packages.

Owner

Current status

Detailed Description

The change is intended to give developers a starting point to be able to use OpenCL and to improve existing OpenCL implementations.

The change will include the following sub changes:

  • Update existing packages if needed
    • gegl (to be investigated)
    • ocl-icd (done)
  • Potential projects to be packaged:
    • Package khronos icd - probably not
    • Package piglit - This will be a test suite for the OpenCL implementations, has some non-fedora deps (PACKAGED)
    • Package gst-plugins-cl - Gstreamer plugin for OpenCL, needs an update to gst-1.0 (NEW)
  • Other stuff:
    • Add a new group to comps or a opencl-dev package?
    • Add virtual provides to the OpenCL implementations - So a app requiring OpenCl just needs to require the virtual package (so any provider)
    • Version opencl-headers

Benefit to Fedora

Developers will have an easier start to develop OpenCL based software on Fedora. Furthermore this shall be seen as a step o bring OpenCL based software to Linux in general.

How To Test

Basic

  1. Install clinfo
  2. Run clinfo
  3. Information about supported OpenCL devices should appear

CPU-Only

Testing can be done on any CPU suported by pocl (x86_64, for now)

  1. Install ocltoys
  2. Run ./smallptgpu -o CPU
  3. An image should appear slowly (or very slowly on slow machines)

GPU-Only

Testing can be done on AMD/ATI GPUs (r600)

  1. Install ocltoys and mesa-opencl (TBD)
  2. Run ./smallptgpu -o GPU
  3. An image should appear
