By the way, it ~seems~ like the patch set confuses the idea of the PCIe Capability Device Control[Relaxed Ordering Enable] with the device's ability to handle incoming TLPs with the Relaxed Ordering Attribute set. These are completely different things. The PCIe Capability Device Control[Relaxed Ordering Enable] solely governs the ability of the device to _send_ TLPs with the Relaxed Ordering Attribute set. It has nothing whatsoever to do with the handling of incoming TLPs with the Relaxed Ordering Attribute set. In fact, there is any standard way to disable receipt processing of such TLPs. That's kind of the whole point of the majority of the patch. If there was a separate "Ignore Incoming Relaxed Ordering Attributes" then we'd mostly just have a quirk which would set that for problematic devices. | ||||||||||||
