<pre>I posted this bug on the (user) mailing list without getting any answers.
Orignal posting:
<a href="http://lists.freedesktop.org/archives/mesa-users/2014-June/000837.html">http://lists.freedesktop.org/archives/mesa-users/2014-June/000837.html</a> and
<a href="https://github.com/vchuravy/qjulia_gpu/issues/1">https://github.com/vchuravy/qjulia_gpu/issues/1</a>
The gist of what I am trying to do is:
after creating the correct OpenCL and OpenGL contexts and the Texture and Image
object I want to do the following calls to copy the computed information from
the OpenCL Buffer to the Image.
glFlush
clEnqueueAcquireGLObjects
clEnqueueCopyBufferToImage
clEnqueueReleaseGLObjects
clFlush
After clEnqueueAcquireGLObjects I get the following error:
"intel_do_flush_locked failed: No such file or directory"
The command itself succeeds but if I put a breakpoint on it and step through
the rest of the function I get that error right after the call.
The problem might stem from my setup. I am using the AMD OpenCL implementation
on an Intel CPU in combination with mesa on an Intel HD3000.
On the other hand if I use llvmpipe it works fine and I also don't get an error
when running it with INTEL_NO_HW=1
Since I am new to mesa debugging how would I go about to get you more usable
information? In the Github repo linked above I have a small c test case for the
scenario I am describing and which reproduces the problem on two different
laptops reliably.
