Hi all, As it's a new tracing device for PCIe traffic, any comments about the driver or the user interface is appreciated. Thanks. On 2020/6/13 17:32, Yicong Yang wrote: > HiSilicon PCIe tune and trace device(PTT) is a PCIe Root Complex > integrated Endpoint(RCiEP) device, providing the capabil

[RFC PATCH] hwtracing: Add HiSilicon PCIe Tune and Trace device driver

2020-06-13 Thread Yicong Yang
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 parameters(tune), and trace the TLP headers to the memory(trace). Add the driver for the device to enable its functions. The
