The _HPX Type 0 setting record is essentially identical to _HPP, but the spec (ACPI rev 5.0, sec 6.2.8.1) says it should be applied to PCI, PCI-X, and PCIe devices, with settings being ignored if they are not applicable. Some platforms with both conventional PCI and PCIe devices provide only _HPP (not _HPX), so treat _HPP the same way as an _HPX Type 0 record and apply it to PCIe devices as well as PCI and PCI-X.
