HiSilicon PCIe tune and trace device(PTT) is a PCIe Root Complex
integrated Endpoint(RCiEP) device, providing the capability
to dynamically monitor and tune the PCIe traffic(tune),
and trace the TLP headers(trace). The driver exposes the user
interface through debugfs, so no need for extra user space tools.
The usage is described in the document.
