From 48dc4241c9cd62bfbe33625e669e21d7081d35fa Mon Sep 17 00:00:00 2001 From: Rob Clark Date: Tue, 16 Apr 2019 16:13:28 -0700 Subject: drm/msm: add param to retrieve # of GPU faults (global) For KHR_robustness, userspace wants to know two things, the count of GPU faults globally, and the count of faults attributed to a given context. This patch providees the former, and the next patch provides the latter.
