User defined data is not directly support but can be added if you add a custom generator. There is not a great deal of documentation about how to do this. An example generator is: https://git.rtems.org/rtems-tools/tree/linkers/rtld-trace-buffer.ini You could add anything specific you want. It is not a great solution but tracing into data being passed by pointers is difficult. You would need to use the various options to get a copy of the trace wrapper file and then get the generator to see the headers and various data you want. > If there isn't support already, maybe some parts of the trace > infrastructure can be reused, notably the backed for storing the data, > and/or sending it out over the network.
