Processor Configuration Registers
2.10.28 SS—Subsystem ID and Subsystem Vendor ID Register
System BIOS can be used as the mechanism for loading the SSID/SVID values. These
values must be preserved through power management transitions and a hardware
reset.

2.10.29 MSI_CAPID—Message Signaled Interrupts Capability ID
Register
When a device supports MSI it can generate an interrupt request to the processor by
writing a predefined data item (a message) to a predefined memory address.
The reporting of the existence of this capability can be disabled by setting MSICH
(CAPL[0] @ 7Fh). In that case walking this linked list will skip this capability and
instead go directly from the PCI PM capability to the PCI Express capability.
