From 8a1a38661f5693409ad92b7ce60189dc52fe4ff6 Mon Sep 17 00:00:00 2001 From: Tomeu Vizoso Date: Wed, 24 Feb 2016 09:04:04 +0100 Subject: lib: Add igt_create_bo_with_dimensions igt_create_bo_with_dimensions() is intended to abstract differences between drivers in buffer object creation. The driver-specific ioctls will be called if the driver that is being tested can satisfy the needs of the calling subtest, or it will be skipped otherwise.
