Bugzilla

For a while I thought Apple's new error numbers might give me leverage on the bug or bugs that (from the crash numbers) badly plague apps that use OpenGL with Apple's AMDRadeonX4000 graphics drivers. Now I no longer think so. Crashes with both error numbers still peter out in the trackless jungle of `IOAccelResource2::prepare()` and `AMDRadeonX4000_AMDAccelResource::prepare()` -- the same place I ended up at bug 1576767. None of this code sets any "context errors" (since they aren't methods of `IOAccelContext2` objects). So the new error numbers don't help here.

I've tried some of the same tricks I used at bug 1576767, and some new ones, to trigger these crashes. None worked. I messed with the "resource" objects "attached" to the "BindDataBuffer" and "ResourceList" tokens. I also messed with those tokens themselves. Virtually everything I tried triggered a crash -- just not the right ones.

There's probably nothing more I can do until I gain new insights or information.
