I'm struggling with the code to understand the "duty and soul" of the "qemu_cpu_is_self" function (@cpus.c), and I quite not get it.
I see that this function is called from some points. E.g., from tcg_hangle_interrupt and run_on_cpu. Amongst others. Sometimes, seems to me that this function duty is "returns if the actual thread is an VCPU thread" and sometimes the duty is "return if the actual thread is specifically this VCPU thread". On non-KVM QEMU vanilla, this makes no difference because of a unique VCPU thread. But imagine that there is an emulation thread which controls multiple VCPU threads... ... then I'm stuck. Somebody can enlighten me? The in-code comments don't help me anymore, and I'm a little thick following the code logic. Thanks! Alex Barcelo
