Content-Type: text/plain; charset=UTF-8; format=flowed Content-Transfer-Encoding: 7bit X-GND-Sasl: jeanmichel.hautbois@yoseli.org 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
