Shinpei's Kato talk

Before being able to run GPGPU kernels on the GPU, we need to have an API to
handle the upload, allocate memory and read/write from/to the GPU.

We think that our runtime should follow the CAL specifications
(https://github.com/shinpei0208/cal-spec) and so should every other driver.

If you would like to do this task, you'll have to communicate implement the
interface for nvidia but also try to make it portable so as AMD could also use
this library to send commands to their GPU.

Please have a look at Shinpei's presentation.

This task is a great way for new comers to learn their way into Nouveau. Please
contact Martin Peres (mupuf) and Shinpei Kato (shinpei) if you consider
applying for this task!

github cal-spec link is broken.  Is this document (Dec 2010) an appropriate
spec?

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
