From: Yicong Yang <yangyicong@hisilicon.com>
This patchset adds the perf tool support for HiSilicon PCIe Tune and Trace device [1]. The device driver makes use of perf AUX trace for tracing TLP (Transaction Layer Packet) headers of PCIe. The trace can be started 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 changelog before v11 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.
