From f796d9958b2b85696b572a4c686c758eb0323c2b Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Fri, 11 Jul 2014 20:38:38 +0100 Subject: [PATCH] igt/gem_tiled_swapping: Speed up slightly The exercise is moving tiled objects in and out of swap. They are moved en-block and we test them all, therefore we can randomly test different bytes from each buffer to have reasonable coverage of all tiles. This shifts the bulk of the work from checking the tiled bo to kswapd.
