aspm - get current state? difference between "performance" and "off"?

Hi

On a running system how can I know current (active) ASPM policy?
I've tried this command and so think that ASPM is disabled on my system, am I correct? What is right way to check ASPM status?

[root@localhost]# lspci -vv | grep ASPM

From documentation:
performance - disables ASPM to allow PCIe links to operate with maximum performance.

What is the differenct between "pcie_aspm=off" and "pcie_aspm .policy=performance". Is it the same?

Thanks,
Oleg
