Hi, This series implements ARB_compute_variable_group_size written against GL 4.3. This extension allows to dispatch variable work group size via a new function called glDispatchComputeGroupSizeARB().
Because this extension is pretty similar to ARB_compute_shader, all Gallium drivers which already support compute shaders will expose ARB_compute_variable_group_size with that series. I did write a bunch of piglit tests, have a look here if you want: https://lists.freedesktop.org/archives/piglit/2016-September/020755.html All tests pass on Fermi (GF119) as well as all previous compute shaders tests. Marek, Nicolai and other AMD folks, I don't know if radeonsi will need a fix somewhere for handling a variable work group size, but as I don't have the hardware, I can't test. Let me know if something needs to be slighty updated. Please review, Thanks!
