The device driver makes use of perf AUX trace for tracing TLP (Transaction Layer Packet) headers of PCIe. The trace can be used by `perf record` and the traced data can be decoded by `perf report` with this patchset. The detailed usage is documented in [1]. This is split from the v11 series as suggested to send driver part and perf tool part separately. The perf tool part has no change since v11. The whole changelog can be found at [2]. Since the driver has been accepted, wish to have perf support along with the PTT driver to enable the full support.
