Subject[PATCH v14 0/3] Add perf support for HiSilicon PCIe Tune and Trace device
Date
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.
