3.

What is the expected output? What do you see instead?
Normal operation.

What version of the product are you using? On what operating system?
r4434 with OCL, Vista x64, ATI 4870.

Please provide any additional information below.
You can get these drivers here:

Screenshot of the very first error: http://i33.tinypic.com/5d0vns.png

After that, endless errors showing:

Error: Failed to create compute kernel!
Error queueing kernel

Is this ATI's fault or Dolphin's fault?

Of course, as stated in the issue and in the provided link...

This issue has been confirmed by other people with ATI cards and this driver.

I dont think its a great idea to report something based on a beta driver...

After r4439 the first error is the same, but:

Error: Failed to create compute kernel!
Error queueing kernel

Have changed to:

OpenCL error: Failed to create compute kernel! CL_INVALID_PROGRAM (-44)
OpenCL error: Failed to enqueue kernel CL_INVALID_KERNEL (-48)

i have read somewhere that ati openCL with these beta drivers = software emulation ?!

can somebody confirm that?

My understanding is that it falls back to software if it can't do it on the hardware.
I'm basing that off the fact that if you run the samples without the OpenCL
compatible drivers it'll produce a warning and complete the task in software, but I'm
not 100% sure.

The thing is that with these drivers OpenCL code can run in both CPU and GPU, at the
same time. AMD/ATI was promoting this in some powerpoint slides when it was released.
But that doesn't explain the errors we ATI users are getting when running Dolphin's
OpenCL code. Any answers from the developers? Dolphin or ATI's fault?

not really sure but I attended a conference with Microsoft and ati/amd and they have
said they are going to support Opencl completely. Lets just hope the drivers stand up
to nvidia's

The problem here is ATI driver failing to compile some correct code. There are some
workaround for the first compilation problems but we shouldn't use them and wait for
more complete drivers.

haha! So the OpenCL C in the drivers act differently....
Weird, I thought they were standardized.

It's almost for sure an ATI driver bug.
I think we should close it as invalid at all...

Yup, same errors. But! Even if the official 9.12 have support for it, the SDK 2.0 is
beta. >_<

Nevertheless, according to the changelog for 2.0-beta4:

"ATI Stream SDK v2.0 OpenCL™ is certified OpenCL™ 1.0 conformant by Khronos."

With a reference to:

"Conformance logs submitted for the ATI Radeon™ HD 5800 series GPUs, ATI Radeon™ HD
5700 series GPUs, ATI Radeon™ HD 4800 series GPUs, ATI FirePro™ V8700 series GPUs,
AMD FireStream™ 9200 series GPUs, ATI Mobility Radeon™ HD 4800 series GPUs and x86
CPUs with SSE3."
