Hi. I tried to use vtune (Intel VTune Amplifier XE 2011 Update 9 (build 229127)) to profile a modified qemu on linux (kernel version: 3.3.7). but vtune reported: "vtune amplifier The application uses the notification signal for its own needs", and vtune thoughts the profile was over, but in fact it had profiled nothing. I also used vtune to profile qemu which was not modified, and it could work well. In our modified qemu, we have used the SIGRTMIN, SIGRTMIN+1,SIGRTMIN+2,SIGRTMIN+3,SIGRTMIN+4. Dose this mean the signals above vtune also uses? and how can I use vtune to profile our modified qemu?
