to bring the system back up if all cores in the whole system are idle and power gated, memory in SR etc... is typically < 250 usec (depends on the exact version of the cpu etc). But the moment even one core is running, that core will keep the system out of such deep state, and waking up a consecutive entity is much faster
to bring just a core out of power gating is more in the 40 to 50 usec range
Out of curiosity, what happens to PCIe when you bring a package down like this ?
