6 | A System Trace Module (STM) is a device exporting data in System | |
7 | Trace Protocol (STP) format as defined by MIPI STP standards. | |
8 | Examples of such devices are Intel(R) Trace Hub and Coresight STM. | |

10 | Say Y here to enable System Trace Module device support. | |

16 | help | |
17 | This is a simple dummy device that pretends to be an stm device | |
18 | and discards your data. Use for stm class testing. | |

25 | This is a kernel space trace source that sends kernel log | |

28 | If you want to send kernel console messages over STM devices, | |

33 | help | |
34 | This is a kernel space trace source that sends periodic | |
35 | heartbeat messages to trace hosts over STM devices. It is | |
36 | also useful for testing stm class drivers and the stm class | |
37 | framework itself. | |

45 | help | |
46 | This option can be used to copy the output from kernel Ftrace | |
47 | to STM engine. Enabling this option will introduce a slight | |
48 | timing effect. | |
