Other things came up, didn't get around to installing libdrm git yet. But for kicks I've taken the logged gem_objects "objects" data and piped it through gnuplot: http://strangesoft.net/gem_objects_plot.png The major dip is the gpu hung issue I had, with a subsequent reboot. Interestingly enough, I just went to check the current count, between the time I started writing the gnuplot spec and the script to convert the log to tabular form, the objects count has increased a bunch: http://strangesoft.net/gem_objects_plot2.png >From 35k, up to 37k. It seems to keep increasing. -- Thomas Fjellstrom tfjellst...@shaw.ca _______________________________________________ Intel-gfx mailing list Intel-gfx@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/intel-gfx
