gdb debugger attach to a real time process in non stop mode

Показать описание
gdb non stop mode is a way to execute or attach a process supposedly without stopping the processes. This video presents how to attach a well known real time benchmark program - cyclictest. Once the process is attached we get a huge jitter.
I believe the only way to get information from an executing real time program, is by embedding some sort of cli into it ( example libcli ).
