| A System Trace Module (STM) is a device exporting data in System |
| Trace Protocol (STP) format as defined by MIPI STP standards. |
| Examples of such devices are Intel(R) Trace Hub and Coresight STM. |
| |
| Say Y here to enable System Trace Module device support. |

| config STM_DUMMY |
| tristate "Dummy STM driver" |
| help |
| This is a simple dummy device that pretends to be an stm device |
| and discards your data. Use for stm class testing. |
| |
| If you don't know what this is, say N. |

| config STM_SOURCE_CONSOLE |
| tristate "Kernel console over STM devices" |
| help |
| This is a kernel space trace source that sends kernel log |
| messages to trace hosts over STM devices. |
| |
| If you want to send kernel console messages over STM devices, |
| say Y. |

| config STM_SOURCE_HEARTBEAT |
| tristate "Heartbeat over STM devices" |
| help |
| This is a kernel space trace source that sends periodic |
| heartbeat messages to trace hosts over STM devices. It is |
| also useful for testing stm class drivers and the stm class |
| framework itself. |
| |
| If you want to send heartbeat messages over STM devices, |
| say Y. |

| config STM_SOURCE_FTRACE |
| tristate "Copy the output from kernel Ftrace to STM engine" |
| depends on FUNCTION_TRACER |
| help |
| This option can be used to copy the output from kernel Ftrace |
| to STM engine. Enabling this option will introduce a slight |
| timing effect. |
| |
| If you want to send kernel Ftrace messages over STM devices, |
| say Y. |
