From 21105bc186d188f0bfc2f41c52b4b0ceb6742cf5 Mon Sep 17 00:00:00 2001 From: Pauli Nieminen Date: Wed, 10 Mar 2010 13:35:59 +0200 Subject: libdrm: Move intel_atomic.h to libdrm core for sharing. intel_atomic.h includes very usefull atomic operations for lock free parrallel access of variables. Moving these to core libdrm for code sharing with radeon.
