For one month from mid-june to mid-july, Mesa master was setting I915_GEM_DOMAIN_GTT in the workaround pipe control. That was changed to be _INSTRUCTION, because _GTT caused kernel oopses, and query objects had already been doing _INSTRUCTION since forever. There are no uses of MI_STOREs in the driver. I'd say the minor ABI change potential in here is safe. -------------- next part -------------- A non-text attachment was scrubbed...
