<pre>Please enable drm.debug=0xf to get drm core debugging, *or* apply this patch to
debug the hotplug events:
diff --git a/drivers/gpu/drm/drm_sysfs.c b/drivers/gpu/drm/drm_sysfs.c
index ab1a5f6dde8a..6abf092d9eb4 100644
--- a/drivers/gpu/drm/drm_sysfs.c
+++ b/drivers/gpu/drm/drm_sysfs.c
@@ -481,7 +481,7 @@ void drm_sysfs_hotplug_event(struct drm_device *dev)
char *event_string = "HOTPLUG=1";
char *envp[] = { event_string, NULL };
- DRM_DEBUG("generating hotplug event\n");
+ DRM_DEBUG_KMS("generating hotplug event\n");
kobject_uevent_env(&dev->primary->kdev->kobj, KOBJ_CHANGE, envp);
}
Now, doing hotplug and looking at both udevadm monitor and dmesg, do you see
cases where:
a) there's the "generating hotplug event" in dmesg, but you do *not* get it in
udevadm monitor
*or*
b) you do hotplug but the message is not in dmesg and you don't get it in
udevadm either.</pre>
