Direct Media Interface (DMI)
Direct Media Interface (DMI) connects the processor and the PCH. Next generation DMI
2.0 is supported.
2.0 is supported.
Note:
Only DMI x4 configuration is supported.
2.3.1
DMI Error Flow
DMI can only generate SERR in response to errors, never SCI, SMI, MSI, PCI INT, or
GPE. Any DMI related SERR activity is associated with Device 0.

2.3.2
Processor / PCH Compatibility Assumptions
The processor is compatible with the Intel 7 Series Chipset PCH products.
2.3.3
DMI Link Down
The DMI link going down is a fatal, unrecoverable error. If the DMI data link goes to
data link down, after the link was up, then the DMI link hangs the system by not
allowing the link to retrain to prevent data corruption. This link behavior is controlled
by the PCH.

allowing the link to retrain to prevent data corruption. This link behavior is controlled
by the PCH.
Downstream transactions that had been successfully transmitted across the link prior
to the link going down may be processed as normal. No completions from downstream,
non-posted transactions are returned upstream over the DMI link after a link down
event.
