From 7be235c1247a8cf51f55938ef05cb41708924b8f Mon Sep 17 00:00:00 2001 From: Tomeu Vizoso Date: Fri, 22 Apr 2016 11:08:45 +0200 Subject: lib: Actually use provided size when creating BO When reworking igt_create_fb_with_bo_size to use igt_create_bo_with_dimensions, we mistakenly stopped acknowledging non-zero size parameters. To fix this, we move the core of the code to create_bo_for_fb and teach it to use the GEM APIs when a size is passed. igt_create_bo_with_dimensions ends up calling just create_bo_for_fb with a zero size because now the later is more generic than the former. Also, create_bo_for_fb now returns the handle of the BO that was created, as there's no point anymore in having it be a parameter passed by reference.
