And the other pencilled in suggestion I have is that you grab the THP/memfd work and put together a userptr igt that can allocate and utilize huge pages. For that we will need a I915_PARAM to report the supported pages sizes (and then have to mask that against the THP supported pages sizes). -Chris _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/intel-gfx
