[Conn O Griofa <connogriofa@xxxxxxxxx>]

Final test: kernel 2.6.34-rc5 + stock drivers + proposed X server
update.

X server uptime: approximately 1 hour.

conn@nx9010:~$ glxinfo | grep "GLX version"
GLX version: 1.2

conn@nx9010:~$ pid=`pidof X` ; for t in `seq 1 10`; do eog /usr/share/backgrounds ; echo `grep "object bytes" /sys/kernel/debug/dri/0/gem_objects` `ps ocomm,vsz,rss $pid |grep X`; done

As you can see, the leak is still occurring. After reaching ~300MB in
object bytes, the computer began to slow down due to excessive I/O and
disk swapping, so applications were slower to load and respond; however,
in periods of calm I/O activity, graphics performance is absolutely
fine. I see no graphical slowdown whatsoever!

To summarise:
Kernel 2.6.32-21-generic + proposed X server from this bug report = memory leak, graphical slowdown
Kernel 2.6.32-21-generic + xorg-edgers packages = memory leak, graphical slowdown
Kernel 2.6.34-rc5 + proposed X server from this bug report = memory leak, no discernible graphical slowdown
Kernel 2.6.34-rc5 + xorg-edgers package = memory leak, no discernible graphical slowdown

In other words: 
a) I get a memory leak in all cases, with or without the patched X server;
b) the newer kernel eliminates any graphical performance impact from the memory leak.

I'm not sure in what direction to proceed; since it seems that most
people are seeing the bug fixed, perhaps this is a separate leak that's
not related to 03_fedora_glx_versioning.diff and
04_fedora_glx14-swrast.diff. Shall I file a new bug, and if so, against
what component?
