But where's the explanation for persisting with an inflexible design? I still do not like the static page size assignments, and trying to force that down into the GTT, rather than it percolating up. -Chris -- Chris Wilson, Intel Open Source Technology Centre ___ Intel-gfx mailing list Intel-gfx@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/intel-gfx
[Intel-gfx] [RFC PATCH 00/18] drm/i915: initial support for huge gtt pages V2
Same as before, folding in review comments. Notably we now hook in transparent huge pages through by shmem, and *attempt* to deal with all the fun which that brings. Again should be considered very much RFC. So far I have only gone as far as testing 2M pages on my BDW machine.
