Hello Dave,

first all the best for your newborn and your whole family!

Thanks,

Second: What could be differend between r6xx/r7xx and EG+ (NI, here) that the below fixes the 'gsraytrace' GPU hang on the later but NOT on the former?

Any ideas, hints where I could start? r6xx/r7xx do not have any TESS support as we now. So where to start? Disabling some lines of your commit and try?

This commit just fixed things by luck on EG I suppose, it must be the NOP at the end of the shader, and I think on r600/700 that could should still happen,

I'd probably need to spend some time staring at fglrx dumps to work out why we crash, does R600_DEBUG=nosb help at all?

Dave.
