One option is to implement [[ 
https://sourceware.org/gdb/current/onlinedocs/gdb/Branch-Trace-Format.html | 
btrace ]] request in the ProcessGDBRemote and make remote stubs support it.

I'm also interested in live tracing for a custom process plugin which obtains 
instruction history in its own way. So, it would be good if a real 
process/thread provides data to the tracing plug-in.
