Description Matt Turner gentoo-dev

RDEPEND contains

   opencl? ( x11-drivers/ati-drivers:* )

This is terrible. We have virtual/opencl for a reason. Please use it.

Okay, I see the comment

# Since not using OpenCL with nVidia, depend on ATI binary
# blobs as Cycles with OpenCL does not work with any open
# source drivers.

Marking as INVALID :(

I'll reword the comment a bit better. In the next update. Basically, the render time witbOpenCL using the nVidia binary driver is very slow -- slower than cpu rendering. You might as well use CUDA which is the fastest method of all. Then cycles renderer will not use the open source drivers with OpenCL. I've been trying for a long time to get this to work. I want to use the open source drivers so I keep trying. Hopefully one day!

This isn't the only Program I've had this issue with.

Cheers

virtual/opencl now supports dev-libs/beignet for VIDEO_CARDS=i965.

I've given last rites to ati-drivers, and masked the opencl USE flag on blender and opensubdiv:

    base/package.use.mask: Mask USE=opencl on blender and opensubdiv.
    
    USE=opencl depends exclusively on x11-drivers/ati-drivers, which is
    being given its last rites.

If you want to change USE=opencl to depend on virtual/opencl I'll be happy to take a patch removing the masks.
