Denis Steckelmacher (https://steckdenis.wordpress.com/2011/08/23/the-gsoc-is-over/) has been working hard to get OpenCL working on the CPU.

At the XDC2011, we discussed how GPGPU should be handled and we kind of agreed on what we should do. This can basically be summed up as using the LLVM IR for compute. This means we need to implement LLVM backends for our GPUs. See the Mesa_compilers.pdf attachment.

Also, the runtime bits should be written according the Compute Abstraction Layer specifications (https://github.com/shinpei0208/cal-spec).

This bug report is actually a meta one that is tracking the development of OpenCL on Nouveau.

It appears that this bug report has laid dormant for quite a while. Sorry we haven't gotten to it. Since we fix bugs all the time, chances are pretty good that your issue has been fixed with the latest software. Please give it a shot. (Linux kernel 3.10.7, xf86-video-nouveau 1.0.9, mesa 9.1.6, or their git versions.) If upgrading to the latest isn't an option for you, your distro's bugzilla is probably the right destination for your bug report.

In an effort to clean up our bug list, we're pre-emptively closing all bugs that haven't seen updates since 2011. If the original issue remains, please make sure to provide fresh info, see http://nouveau.freedesktop.org/wiki/Bugs/ for what we need to see, and re-open this one.

Thanks,

The Nouveau Team
