Cota" , Colin Xu Errors-To: qemu-devel-bounces+qemu-devel=archiver.kernel.org@nongnu.org Sender: "Qemu-devel" move the call to qemu_init_vcpu inside cpu_common_realizefn, so it does not need to be done explicitly in each target cpu. This makes it a little bit better, but still the way realize is done continues to be bad; ideally the cpu_list_add would be done in common_cpu, and in this case we could avoid even more additional calls in target/xxx/cpu.c, but this cannot happen because target cpu code, plugins, etc now all rely on cpu->index, since no particular order was defined previously, so we are stuck with the freak call order for the target cpu realizefn. After this patch the target/xxx/cpu.c realizefn body is now: void mycpu_realizefn(DeviceState *dev, Error **errp) { /* ... */ cpu_exec_realizefn(CPU_STATE(dev), errp); /* ... anything that needs done pre-qemu_vcpu_init */ xcc->parent_realize(dev, errp); /* does qemu_vcpu_init */ /* ... anything that needs to be done after qemu_vcpu_init */ } Note: better do some testing for all targets for this.
