I still don't like this. We're in a situation where we clearly have to disable one feature or the other on SNB - but we're disabling the one that's going to be useful to a large number of people, and leaving the niche feature enabled. If we're going to merge this then let's turn off iommu on SNB by default. -- Matthew Garrett | mj...@srcf.ucam.org _______________________________________________ Intel-gfx mailing list Intel-gfx@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/intel-gfx
