Can you give the attached patch a whirl and let me know if it fixes the problem?
As I indicated in my previous note, vmwgfx should be the only affected driver because it looks at dev_mapping in the open hook (others do it when they create an object, so they are not affected). I'll probably revise it (and I'll have some general questions about drm_open syscall) before officially send the patch, but I wanted to get something quickly to you to check if it fixes your problem. I hope that your vmwgfx test environment is such that you can reproduce the original problem. thanks, -- Ilija -------------- next part --------------
