Abstract
Examples described herein relate to link training between network connected devices. In some examples, an amount to extend link training is determined. The amount to extend link training can be determined by: receiving, by a receiver in a first device, signals over a lane from a transmitter in a second device, the signals indicating capability to extend link training time and amount to extend link training time; determining, at the first device, a link training time based on a default link training time and an amount to extend link training time; and performing link training based on the determined link training time. In some examples, the determined amount is highest common denominator of the received identified capability and transmitted indicated capability.
Claims20
An apparatus to be associated with a communications link and a link partner, the apparatus comprising:
- transmitter circuitry;
- and
- receiver circuitry;
- wherein:
- the receiver circuitry is to receive one or more signals via the communications link;
- the one or more signals are for use in association with indicating at least one capability of the link partner;
- the at least one capability of the link partner is associated, at least in part, with extending link training time of the link partner beyond a first link training time;
- the transmitter circuitry is to transmit one or more other signals via the communications link;
- the one or more other signals are for use in association with indicating at least one capability of the apparatus;
- and
- the at least one capability of the apparatus is associated, at least in part with extending link training time of the apparatus.
At least one non-transitory machine-readable storage medium storing instructions for being executed by at least one machine that is to be associated with an apparatus, the apparatus to be associated with a communications link and a link partner, the apparatus comprising transmitter circuitry and receiver circuitry, the instructions, when executed by the at least one machine resulting in the apparatus being configured for performance of operations comprising:
- receiving, using the receiver circuitry, one or more signals via the communications link;
- and
- transmitting, using the transmitter circuitry, one or more other signals via the communications link;
- wherein:
- the one or more signals are for use in association with indicating at least one capability of the link partner;
- the at least one capability of the link partner is associated, at least in part, with extending link training time of the link partner beyond a first link training time;
- the transmitter circuitry is to transmit one or more other signals via the communications link;
- the one or more other signals are for use in association with indicating at least one capability of the apparatus;
- and
- the at least one capability of the apparatus is associated, at least in part with extending link training time of the apparatus.
A method implemented using an apparatus, the apparatus to be associated with a communications link and a link partner, the apparatus comprising transmitter circuitry and receiver circuitry, the method comprising:
- receiving, using the receiver circuitry, one or more signals via the communications link;
- and
- transmitting, using the transmitter circuitry, one or more other signals via the communications link;
- wherein:
- the one or more signals are for use in association with indicating at least one capability of the link partner;
- the at least one capability of the link partner is associated, at least in part, with extending link training time of the link partner beyond a first link training time;
- the transmitter circuitry is to transmit one or more other signals via the communications link;
- the one or more other signals are for use in association with indicating at least one capability of the apparatus;
- and
- the at least one capability of the apparatus is associated, at least in part with extending link training time of the apparatus.
