DMI Lane Reversal and Polarity Inversion

Note:Polarity Inversion and Lane Reversal on DMI Link are not allowed in S-Processor segment. Lane reversal can only be allowed on the PCH side.

Example for DMI Lane Reversal Connection

  1. DMI Lane Reversal is supported only on PCH-S and not on the Processor.

  2. L[7:0] - Processor and PCH DMI Controller Logical Lane Numbers.

  3. P[7:0] - Processor and PCH DMI Package Pin Lane Numbers.
