From f1294585d8e177b25acd028d90f23f335d6695fb Mon Sep 17 00:00:00 2001 From: Nanley Chery Date: Tue, 5 Sep 2017 11:45:07 -0700 Subject: [PATCH] drm/i915/cnl: Allow the reg_read ioctl to read the RCS TIMESTAMP register This enables the Mesa driver to advertise support for ARB_timer_query, and thus an OpenGL version higher than 3.2.
