This field represents the snooped value of the AUX write to DPCD address 0x00600. When AUX_SNOOP_DISABLE = 0b, the enable/disable of DP lanes based on the snooped value. When AUX_SNOOP_DISABLE = 1b, then DP lane enable/disable are determined by state of DPx_DISABLE registers, where x = 0, 1, 2, or 3. This field is reset to 0h by hardware when CTLSEL1 changes from a 1b to a 0b.

This field represents the snooped value of AUX write to DPCD address 0x00101 register. When AUX_SNOOP_DISABLE = 0b, DP lanes enabled specified by the snoop value. Unused DP lanes will be disabled to save power. When AUX_SNOOP_DISABLE = 1b, then DP lanes enable/disable are determined by DPx_DISABLE registers, where x = 0, 1, 2, or 3. This field is reset to 0h by hardware when CTLSEL1 changes from a 1b to a 0b.
