From: Marek Olšák Date: Mon, 10 Jul 2017 14:01:28 +0000 (+0200) Subject: ac/gpu_info: if clock crystal frequency is 0, print an error and set 1 X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=3d1a576fa607b5df05cbfe286ef9821ba387344d;p=mesa.git ac/gpu_info: if clock crystal frequency is 0, print an error and set 1 During bring-up, this is often 0. Prevent automatic disablement of ARB_timer_query and demotion of the OpenGL version to 3.2 by setting a non-zero frequency. Print an error message instead.
