Extended link-training time negotiated on link start-up

A method to determine an amount to extend link training, the method comprising:

• 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.

A non-transitory computer-readable medium comprising instructions stored thereon, that if executed by one or more processors, cause the one or more processors to be configured for performance of operations comprising:

• engage in a link training wherein:
• the one or more processors are to receive one or more communication signals identifying capability to extend link training time;
• the one or more processors are to cause transmission of one or more other communication signals indicating including a capability to extend link training time;
• and
• the one or more processors are to determine an amount to extend link training time based on the received identified capability and transmitted indicated capability.
