From bff22f7317a39605d53cf142e2c0f5c424d9c12c Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Sat, 22 Mar 2014 19:21:26 +0100 Subject: lib: Move non-register things out of intel-gpu-tools.h Right now almost everything in there concerns itself with register access. Move everything else out (into drmtest.h for lack of better place) to prepare for api documentation. Also rename intel_drm.c to intel_os.c since it contains OS, not drm abstractions.
