kmemleaks dump

This bug probaly belongs more to kernel DRM driver, but I for now will document
all my findings here.

I am running kmemleak on my system, and I notice that it find what suggests
that nouveau stack leaks BO somewhat.

I attach current kmemleaks dump.

another kmemleak report

I can trigger this memory leak at the rate of 1MB/s with rendercheck on xorg
st.
I'm attaching first 2000 lines of kmemleak report (out of 2.000.000).

interesting.
I tried rendercheck and I couldn't reproduce this.
You use gallium generic xorg driver, right?
I use the standard xf86-video-nouveau DDX driver

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
