This patch introduces a workaround for a case where a uevent is issued by the kernel because of DP link training failing on a connector unrelated to the current test. Since the test depends on receiving a hotplug uevent, it previously passed even though it should not have. False positives also occur due to the plug/unplug events being delayed and issued at resume time. This is mitigated by catching and flushing hotplugs everytime a change is made on connectors, but it is not enough to ensure that all hotplug events were caught and not delayed. The problem here is that it is not possible to find out the exact reason why a uevent is issued by the kernel. A possible way to fix this would be to introduce more fields (the connector name and some reason why the event is triggered would probably be sufficient). _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/intel-gfx
