Adding ftrace support for coldfire ?

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi there !

I always have been a fan of ftrace, in particular when it comes to latency issues debugging.

I would love to use it on my coldfire custom board (M54418 based).
I can see that it needs TRACE_IRQFLAGS_SUPPORT and STACKTRACE_SUPPORT, both are missing.

Is it not doable ? If it is, what is required ? Implementing the save_stack_trace() ? I suppose it is not enough :-) ?

Thanks in advance, as it would be a great helper !

Regards,
JM
