Re: [PATCH 2/2] opencl: Basic OpenCL 1.0 implementation. (try 2)

[Roderick Colenbrander]

It looks fine to me, but I'm worried whether it can work properly in
the end. A few months ago I worked on Cuda support for something (I
implemented nvcuda.dll which is what cuda runtime libraries like
cudart or physx are using). Certain lowlevel nvcuda applications
worked, but more fancy applications didn't. I had some contact with
Nvidia about it and it was not possible to support Cuda without
assistance on their side.

OpenCL is a little different of course, but I fear that not all OpenCL
implementations will like wrapping. What OpenCL applications have you
tried so far? The Nvidia GPU Computing SDK (or whatever it was called)
has a ton of samples for both Cuda and OpenCL. Do all their OpenCL
samples work?

I added wine OpenCL support in order to get OpenCL functionality in 
eyeon Fusion 6.1 [*] and it works with both built-in tools and Fuses. I 
also tested with a number of (not all) samples from the Nvidia GPU 
Computing SDK. It works with the simple ones, like oclDeviceQuery.exe 
and oclBandwidthTest.exe as well as the more complex ones, like 
oclParticles.exe

I only tested with Nvidia GT240 hardware, 260.19.x series drivers, but I 
will get a chance to test with an ATI FirePro V5800 at some point in the 
future.

So far, I have only implemented support for the mandatory core OpenCL 
1.0 functionality. In particular, native kernels (optional feature) are 
not supported and probably never will be.

Extensions are not yet supported, they will each have to be dealt with 
on individual basis, but I suspect that features such as cl_khr_fp64 
support should be doable.

OpenGL sharing is also not supported yet - mainly because I don't know 
enough about wine OpenGL internals. I'm hoping that I will get some help 
with OpenGL sharing once the basic OpenCL implementation is in the wine 
tree.
