I started learning Tejas yesterday. I am able to run a simple "Hello World" executable using pin emulator.
But if I want to use a full system simulation using QEMU, I am really confused about how to generate trace file (.gz) that is passed as the fourth parameter. I am able to launch a simple virtual machine using qemu-system-x86_64 -hda ubuntu-test.img -cdrom <ubuntu>.iso -m 1024 -enable-kvm, but I seem to be stuck here. Based on the slides and
https://www.cse.iitd.ac.in/~prathmesh/projects.html, it seems that there is some special utility called "QemuTrace," but I am not sure how or where to access it.
