config STM tristate "System Trace Module devices" select CONFIGFS_FS select SRCU help 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. if STM 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. endif
