          Priority: medium
            Bug ID: 79431
          Assignee: dri-devel@lists.freedesktop.org
           Summary: OpenGL OpenCL interop results in corrupted
                    renderbuffer object image
          Severity: normal
    Classification: Unclassified
                OS: All
          Reporter: pavol@klacansky.com
          Hardware: Other
            Status: NEW
           Version: git
         Component: Drivers/Gallium/r600
           Product: Mesa

I use APP SDK with OpenCL running on CPU and r600 driver on GPU (AMD Mobility
3650) to compute image. If I use OpenCL image, I get correct result, however if
I want to display image using OpenGL (interop), it is corrupted.

I create renderbuffer object, than link it with OpenCL
(clCreateFromGLRenderbuffer) and then after image was computed I blit it
to back buffer.

I tested it in lab on nVidia proprietary driver and it works well, I suspect
the problem is in renderbuffer sharing.

OpenCL is 1.2, OpenGL 3.3.

If I use LIBGL_ALWAYS_SOFTWARE=1 I get uncorrupted image, but it is all black.

Hi,

I have tried looking information for your card regarding OpenCL and I haven't
been able to found anything. Are you sure that it supports it?

Besides, I think that clover doesn't support your card, so even if it does
support OpenCL I think that it wouldn't work.

And, I'm afraid that clover doesn't implement yet clCreateFromGLRenderbuffer.

As I mentioned, I use CPU as OpenCL device using APP SDK.

I have a problem with OpenGL OpenCL interop. OpenCL from AMD APP SDK works
fine, the problem is when I use Gallium driver for OpenGL, I get corrupted
image.

r600 does support OpenCL, but only on EG/NI (Radeon HD 5000/6000).

(In reply to Vedran Miletić from comment #4)
> r600 does support OpenCL, but only on EG/NI (Radeon HD 5000/6000).

my understanding is that this bug is not about clover, but getting r600g GL
work with third party CL.
afaik Marek was looking into that, but that might have been just for GCN+. (the
conclusion might still be that it's unsupported)
