Abstract

Techniques for port selection are described herein. The techniques may include an apparatus a transceiver including a plurality of ports. The apparatus includes a selector to select a port from among the plurality of ports. The port is selected to receive a repair operation to repair a basic input output system.

Claims

1. An apparatus for port selection, comprising:

a transceiver comprising a plurality of ports;

a selector to select a port from among the plurality of ports for receiving an operation to repair a basic input output system.

2. The apparatus of claim 1, wherein the transceiver is configured in isolation mode during the repair operation.

3. The apparatus of claim 2, wherein isolation mode comprises restricting operations of a system-on-chip until the repair operation is complete.

4. The apparatus of claim 2, wherein isolation mode comprises receiving the repair operation without handshake operations over the selected port.

5. The apparatus of claim 1, wherein selection of the selected port is based on a detection of a signal at a voltage bus of the selected port indicating the repair operation is provided at the port.

6. The apparatus of claim 5, wherein the selected port is a first port in an all-in-one port comprising a second port associated with an orientation that is different than an orientation of the first port.

7. The apparatus of claim 6, wherein selection of the selected port is further based on a detection of a signal at an orientation pin associated with the first port.

8. The apparatus of claim 6, wherein the all-in-one port is one among a plurality of all-in-one ports, and wherein the selected port is selected from among a plurality of first and second ports respectively associated with each of the plurality of all-in-one ports.

9. The apparatus of claim 1, wherein the receiver is configured to receive a clock signal associated with the repair operation that is independent of other operations on the port.

10. The apparatus of claim 1, wherein the selector comprises logic, at least partially comprising hardware logic, of a physical layer of the apparatus.

11. A method for port selection, comprising:

selecting a port from among a plurality of ports of a transceiver to receive an operation configured to repair a basic input output system;

receiving the download and execution operation at the selected port.

12. The method of claim 11, further comprising entering the transceiver to isolation mode during the repair operation.

13. The method of claim 12, wherein isolation mode comprises restricting operations of a system-on-chip until the repair operation is complete.

14. The method of claim 12, wherein isolation mode comprises receiving the repair operation without handshake operations over the selected port.

15. The method of claim 11, wherein selection of the selected port is based on a detection of a signal at a voltage bus of the selected port indicating the repair operation is provided at the port.

16. The method of claim 15, wherein the selected port is a first port in an all-in-one port comprising a second port associated with an orientation that is different than an orientation of the first port.

17. The method of claim 16, wherein selection of the selected port is further based on a detection of a signal at an orientation pin associated with the first port.

18. The method of claim 16, wherein the all-in-one port is one among a plurality of all-in-one ports, and wherein the selected port is selected from among a plurality of first and second ports respectively associated with each of the plurality of all-in-one ports.

19. The method of claim 11, wherein receiving the download and execute operation comprises receiving a clock signal associated with the repair operation that is independent of other operations on the port.

20. The method of claim 11, wherein selecting the port is performed at a physical layer associated with the selected port.

21. A system for port selection, comprising:

a basic input output system;

a transceiver comprising a plurality of ports;

a selector to select a port from among the plurality of ports for receiving an operation to repair the basic input output system.

22. The system of claim 21, wherein the transceiver is configured in isolation mode during the repair operation, wherein isolation mode comprises restricting operations of a system-on-chip until the repair operation are complete, and wherein isolation mode comprises receiving the repair operation without handshake operations over the selected port.

23. The system of claim 21, wherein selection of the selected port is based on a detection of a signal at a voltage bus of the selected port indicating the repair operation is provided at the port.

24. The apparatus of claim 23, wherein the selected port is a first port in an all-in-one port comprising a second port associated with an orientation that is different than an orientation of the first port.

25. The apparatus of claim 24, wherein selection of the selected port is further based on a detection of a signal at an orientation pin associated with the first port.
