Tom Stellard's presentation 

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.

--- Comment #1 from Ilia Mirkin <imirkin at alum.mit.edu> ---
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
