From 31811f4b6c5a95de82e47ddf1f37739c3b2cfc58 Mon Sep 17 00:00:00 2001 From: Lyude Date: Wed, 21 Dec 2016 14:00:54 -0500 Subject: igt_core: add igt_constructor This is a simple macro for executing a block of code at the beginning of intel-gpu-tools, before any tests have been ran. Useful for initialization of global resources used in IGT libraries.
