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.
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.
