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.
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.
