Data Register, Offset 0xCF, (RO)
This optional register is used to report power consumption and heat dissipation.
Reported register is controlled by the Data_Select field in the PMCSR and the power
scale is reported in the Data_Scale field in the PMCSR. The data of this field is loaded
from the NVM if power management is enabled in the NVM. Otherwise, it has a default
value of 0x00. The values for the 82574 are as follows:
For other Data_Select values the Data register output is reserved (0b).
Message Signaled Interrupt (MSI) Configuration Registers
This structure is required for PCIe devices. Initialization values of the configuration
registers are marked in parenthesis. Light-blue fields represent read-only fields.
There are no changes to this structure from the PCI 2.2 specification.
MSI Configuration Registers
Capability ID, Offset 0xD0, (RO)
This field equals 0x05 indicating the linked list item as being the MS registers.
Next Pointer, Offset 0xD1, (RO)
This field provides an offset to the next capability item in the capability list. Its value of
0xE0 points to the PCIe capability.
