From 3fad1565720ffd8fc944849ebf21e53b5947c9ed Mon Sep 17 00:00:00 2001 From: shaoyunl Date: Wed, 31 Jan 2024 09:20:07 -0500 Subject: drm/amdgpu: Only create mes event log debugfs when mes is enabled Skip the debugfs file creation for mes event log if the GPU doesn't use MES. This to prevent potential kernel oops when user try to read the event log in debugfs on a GPU without MES Signed-off-by: shaoyunl Reviewed-by: Harish Kasiviswanathan Signed-off-by: Alex Deucher --- drivers/gpu/drm/amd/amdgpu/amdgpu_mes.c | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) diff --git a/drivers/gpu/drm/amd/amdgpu/amdgpu_mes.c b/drivers/gpu/drm/amd/amdgpu/amdgpu_mes.c index 1f3dfbb6bb16..a98e03e0a51f 100644 --- a/drivers/gpu/drm/amd/amdgpu/amdgpu_mes.c +++ b/drivers/gpu/drm/amd/amdgpu/amdgpu_mes.c @@ -1565,9 +1565,9 @@ void amdgpu_debugfs_mes_event_log_init(struct amdgpu_device *adev) #if defined(CONFIG_DEBUG_FS) struct drm_minor *minor = adev_to_drm(adev)->primary; struct dentry *root = minor->debugfs_root; - - debugfs_create_file("amdgpu_mes_event_log", 0444, root, - adev, &amdgpu_debugfs_mes_event_log_fops); + if (adev->enable_mes) + debugfs_create_file("amdgpu_mes_event_log", 0444, root, + adev, &amdgpu_debugfs_mes_event_log_fops); #endif } -- cgit v1.2.3
