Hi, I have successfully integrated the statistical simulation package SimPoint with QEMU. Now I wish to add some commands to QEMU so a user can start or stop simulation. The goal is that at the QEMU command prompt, the user could enter a command like start_simpoint or stop_simpoint. For example:
(qemu) start_simpoint SimPoint started! (qemu) .... /*Time passes.. */ (qemu) stop_simpoint SimPoint stopped! I am curious where I would edit QEMU to look for such commands, some point in the code where I can see what command is passed to QEMU, and do something such as "if strcmp(command, "start_simpoint") == 0" Also, there is another problem, I am able to run QEMU if I tell it to load and boot a linux image. But I am not able to simply boot up to the (qemu) prompt and enter commands from there. I try running QEMU using the following commands: qemu-img create -f qcow c.img 3G ./i386-softmmu/qemu -hda c.img -L ./pc-bios/ -nographic and it loads up to the (qemu) prompt. However, at that point everything freezes. I am running QEMU on a linux host with a dual 64-bit AMD processors, and doing this over an SSH connection. If anyone has any advice on how I can get QEMU to boot to the point where I can enter commands, and how I can monitor these commands within the source code, I would very much appreciate the assistance. ~Shane Brennan UC Santa Cruz
