Hi, All,<br>  <br>   This is a question regarding getting a total count of instructions being executed in qemu.<br>   I would like to know how much instruction it takes to boot into linux on a arm based processor.<br>   This is what I have done: <br>
    - I used qemu-system-arm<br>    - I made a sd card image which contains the proper kernel, uImage and boot loader<br>    - I booted the system using this command ./qemu-system-arm -M beagle -sd /dev/mmcblk0<br>   Note that I used the mameo3-port of qemu to work on beagle board emulation.<br>
<br>   There is an -d option in qemu-system-arm that allows me to do some logging. However, after counting the total number of instruction that has been logged.<br>   I doubt that the -d option only logs the instructions that have been translated, not the instructions that are actually executed. Since the total count I get from my log file is way smaller than what is should be.<br>
  <br>   I wonder if there is anyway, or what modification should I do, to let qemu log the total number of instructions that has been executed. It may involves break the direct block-chaining mechanism inside qemu, I presume. Any advice?<br>
