function profiler of the ftrace
Sorry, I sent to the wrong mailing list, thanks for the reminding.
The fsl-imx51 branch doesn't support too much features of the ftrace,
including FUNCTION_GRAPH_TRACER, DYNAMIC_FTRACE, MMIOTRACE
Do you think is there any other useful options should be enabled?
I can try to see if they're supported in the fsl-imx51 branch.
