Though I think the interaction between lowmemkiller and i915 is broken, I do agree that we need to run our swap tests and that to do so we need to disable lowmemkiller. I would prefer it if only the swap-thrash tests disabled the lowmemkiller though, as I think we still need to test integration behaviour and if lowmemkiller starts killing tests that we think should be well within the limits, that is likely to be our bug. -Chris -- Chris Wilson, Intel Open Source Technology Centre _______________________________________________ Intel-gfx mailing list Intel-gfx@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/intel-gfx
