From 6b9d26089f56fb05c1f13027bfff53a63ba6f64d Mon Sep 17 00:00:00 2001 From: Eric Huang Date: Mon, 14 Apr 2025 11:19:01 -0400 Subject: [PATCH] drm/amdkfd: fix a bug of smi event for superuser rocm-smi with superuser permission doesn't show some of smi events, i.e. page fault/migration, because the condition of "(events & all)" is false. Superuser should be able to detect all events, the condiiton of "(events & all)" seems redundant, so removing it will fix the issue.
