Abstract: Aspects of the embodiments are directed to systems, methods, and apparatuses to determine transmission equalization coefficients (TxEQs) for one or more lanes of a high speed serial link. Embodiments include determining a jitter tolerance for each TxEQ of a plurality of TxEQs for a lane of the link. The jitter tolerance for each TxEQ for the lane is based on a level of jitter induced on the lane to detect a number of errors on the lane; determining a voltage (VOC) margin for each TxEQ for the lane, wherein the voltage margin for the lane is based on a voltage corners test applied to the lane to detect a number of errors on the lane at a high voltage point and a low voltage point; determining a TxEQ that provides maximum jitter tolerance and based on the determined lowest voltage margin; and using the TxEQ for the lane during operation.

Abstract: Redundant acknowledgment between agents performing a loopback test over bidirectional communications bus is described. In one example, in a processor including a communications agent coupled to a bidirectional communications bus, the communications agent initiates loopback communications to a second agent, sends a packet including a redundant acknowledgment sequence to the second agent, receives the packet including the redundant acknowledgement sequence looped back from the second agent, determines whether the received redundant acknowledgment sequence is valid, sends a test sequence to the second agent, receives the test sequence looped back, and if the received redundant acknowledgment sequence is determined to be valid, then checks the received test sequence.

In one example the acknowledgment is performed by initiating loopback communications from a first agent to a second agent, sending a packet including a redundant acknowledgment sequence from the first agent to the second agent, receiving the packet including the redundant acknowledgement sequence looped back from the second agent at the first agent, sending a test sequence from the first agent to the second agent, and receiving the test sequence looped back from the first agent.

Abstract: A condition is detected to cause a component having physical layer circuitry with a transmitter and a receiver to enter a testing state. The transmitter transmits a pre-selected data pattern while comparing data received by the receiver to the pre-selected data pattern during a first phase of the testing state. The transmitter transmits data received by the receiver without comparing the data received by the receiver to the pre-selected data pattern during a second phase of the testing state.
