[Mesa-dev] [PATCH 05/10] ac/gpu_info: if clock crystal frequency is 0, print an error and set 1

[Marek Olšák]

From: Marek Olšák <marek.ol...@amd.com>

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.
