Hi, all I’m trying to figure out how do_savevm works in QEMU. But there is one thing has bothered me quite a lot. I found that vm_stop invoke qemu_cpu_kick_thread to send SIG_IPI to a vcpu thread, and I have understand that in TCG mode, the cpu_signal() function will be invoked as the SIG_IPI handler. But I don’t know what happens in KVM mode. Actually I can’t find the signal handler function. I only find a function named dummy_signal, and it doesn't do anything.
Thanks a lot! -- ----- Shiru Ren Department of Computer Science School of EECS Peking University Beijing, China
