[PATCH V4 0/3] Integration of function trace with System Trace IP blocks

IP blocks allowing a variety of trace sources to log debugging information to a pre-defined area have been introduced on a couple of architecture [1][2]. These system trace blocks (also known as STM) typically follow the MIPI STPv2 protocol [3] and provide a system wide logging facility to any devi

If CONFIG_STM_FTRACE is selected, Function trace data can be writen to sink via STM, all functions that related to writing data packets to STM should be marked 'notrace' to avoid being traced by Ftrace, otherwise the program would stall into an endless loop. Signed-off-by: Chunyan Zhang Acked-by:

[PATCH V4 1/3] tracing: add a possibility of exporting function trace to other places instead of ring buffer only
