https://bugs.freedesktop.org/show_bug.cgi?id=34495 --- Comment #18 from Micael Dias <kam1kaz3@xxxxxxxxx> 2011-06-28 06:53:45 PDT --- @Sergei: no problem. This bug was also hitting on my nerves for months, and I was always curious about how the linux graphics stack actually works, so I decided to see if I could see where this bug was comming from. After having llvm generate some printfs it was pretty obvious that the issue was some kind of buffer overflow. Then generating hardcoded values on generate_fetch() and not having the crash anymore was a key clue that that was corrupting the memory somehow. Funny enough draw_llvm_generate_elts() checks for these buffer overflows, so it was almost copy-paste from there. I'm not even sure this is a proper fix since draw_llvm_generate_elts does a little more than I do here. @Pierre: It's a pitty if it doesn get hardware accelerated. Many CAD apps use GL_SELECT. Can you please give me a hint on how one would go about implementing HW acceleration for it? I'm not sure I'm able to do it, but would be interested in playing with it. -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
