I am starting my QEMU VM with the following command to get the execution traces for a simple hello world program in C.
qemu-system-riscv64 -singlestep -d nochain,cpu -D $trace ${binary}.
For guidance, I am following this tutorial. How is it that in slide 4, the size of the traces are 65K, whereas, my file just keeps growing (in GBs). I understand that it is monitoring the traces and hence the file size grows. My questions are:
Am I using the right command to get the execution traces? If not, please help in getting the correct command to only get the traces for the binary.
I am assuming that by giving the binary file as an argument, QEMU executes it when it launches the window. If this is not the case, how would I execute this hello world program inside the qemu window?
Lastly, I am assuming that the command is not doing full system virtualisation. I just need the traces, so I don't think that will be necessary. Is my assumption wrong? or is this command not sufficient?
Any help would be greatly appreciated. I have been stuck in this for a while now.
