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.

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.

|
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.

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.
