Docks for external graphical processor units

A method, comprising:

• detecting, by a processor, an upstream connection to an external graphical processing unit (eGPU), wherein the upstream connection comprises a plurality of channels;
• disabling, by the processor, a first channel of the upstream connection in response to the upstream connection to the eGPU that is detected;
• and
• transmitting, by the processor, data from a peripheral device that is connected downstream to a host computer that is connected upstream of the eGPU via a second channel of the upstream connection.

A non-transitory machine-readable storage medium encoded with instructions executable by a processor, the machine-readable storage medium comprising:

• instructions to receive data from a downstream peripheral device;
• instructions to determine that an upstream connection interface is connected to an external graphical processor unit (eGPU);
• and
• instructions to transmit the data via a peripheral component interconnect express channel while a display port channel of the upstream connection interface is disabled.
