[Mesa-dev] leak of gem_objects on intel i965

[Lampersperger Andreas]

Hello Stéphane,

I've tried your patch (I adopted it to 7.10.3, see attached patch), but it results in a SEGFAULT:

Thread [1] 12367 (Suspended : Signal : SIGSEGV:Segmentation fault)
                st_visual_to_context_mode() at st_manager.c:309 0xb6ea7be0

                configure_event() at simple.c:81 0x8049982
                ...

In st_framebuffer_create() stfbi->visual was not initialized.

Do I have to apply other patches to 7.10.3?

Hello,

I've tried 2.6.39.1 and the gem_objects leak still exists.

I found the leak also on a i915 not only on a i965.

It only disappears if I set LIBGL_ALLWAYS_SOFTWARE (not really an opinion ;-).

Now I can try to update user space libraries, what lib would you suspect most?

libdrm 2.4.23
xorg-server 1.10.2
xf86-video-intel-2.15
gtkglext-1.2.0
mesa-7.10.2
Or I can continue debugging, if anyone can give me a hint to the following question:

In which function are the buffers freed, which are received
from xserver via DRI2GetBuffersWithFormat(..) at dri2.c:431?


This sounds familiar. You may want to try the patch I posted earlied today ("glx: implement drawable refcounting").

Stéphane
