Which Versions of libdrm mesa xf86_video_intel xorg-server gtkglext linux-kernel
do you use? You think the most suspect part is i915.ko? I watched (via systemtap) all calls to drm_gem_object_alloc(), drm_gem_object_free(), and to drm_gem_object_destroy() (in drm.ko) and I saw that with every realize/unrealize of simple.c there are 2 drm_gem_object_alloc() calls (between other drm_gem_object_allocs/frees) where I cannot found a suitable drm_gem_object_free or .._destroy call. This leads me to suspect the user-space. Or is this wrong, that for every drm_gem_object_alloc()-call there have to be a drm_gem_object_free()-call? Can you give me some hint, where to start debugging/watching in i915.ko? -Andreas -----Ursprüngliche Nachricht----- Von: Chris Wilson [mailto:ch...@chris-wilson.co.uk] Gesendet: Dienstag, 14.

Just replace in > gtkglext-1.2.0/examples the original simple.c with the attached version. Builds fine. I see a flashing quadric (every other frame, the gtkglarea appears unrealized) and watching /sys/kernel/debug/dri/0/i915_gem_objects, the number of bo remains static. I think the most likely suspect is i915.ko. Over the years we've had a number of gem leaks mostly associated with vma references and I'm pretty sure that they have not all been backported to 2.6.33 -Chris -- Chris Wilson, Intel Open Source Technology Centre
