All I enable the trace function with --enable-trace-backend=simple and I create the event file like this g_realloc g_malloc
Then I start the qemu with following command. ./i386-softmmu/qemu-system-i386 -enable-kvm -drive file=../../kvm/ubuntu.img -boot dc -m 512 -usb -monitor stdio -trace events=qemu_trace_events,file=qemu_trace.log After some run time, I run the script like: ./scripts/simpletrace.py qemu_trace_events_parse qemu_trace.log The qemu_trace_events_parse is : g_realloc(addr) g_malloc(addr) The output looks like: g_malloc 1.831 addr=0xb945d1f0 g_malloc 2.498 addr=0xb945d1f0 g_realloc 4.715 addr=0x10 g_realloc 1.520 addr=0xc g_realloc 1.505 addr=0xc The steps I used is correct? I just guess the format of input events file of the simpletrace.py. For so many available events, how could I specify the format of all those events? -- Richard Yang Help You, Help Me
