Abstract

Method, apparatus, system and computer program product for analyzing and reporting the status of an adapter in a data processing system. The system includes a service application having the capability of providing a variety of service functions to permit data to be captured regarding the status of the adapter, and a communication structure to permit data to be transmitted to and received from the service application. The analyzing and reporting system of the invention facilitates the reporting and diagnosis of adapter problems so that encountered problems can be better understood and more easily corrected.

Claims

1. An apparatus for analyzing and reporting the status of an adapter in a data processing system, comprising:

an adapter connectable to a bus of the data processing system for supporting a mechanism with which the adapter is associated;

a service application on said adapter, said service application providing at least one secondary device driver that works in parallel with a device driver of said adapter for providing at least one service function for capturing data regarding the status of the adapter, wherein the at least one service function comprises at least one of configuration, open, close, transmit and receive; and

a communication structure on said adapter for transmitting data to said service application and for receiving said captured data regarding the status of the adapter from said service application.

2. The apparatus according to claim 1, wherein said service application resides on a service processor chip on said adapter.

3. The apparatus according to claim 1, and further including:

at least one register on said adapter; and

means for providing communication between said service application and said at least one register for enabling said service application to provide said at least one service function, wherein said at least one service function further comprises at least one of gathering, setting and clearing said at least one register.

4. The apparatus according to claim 2, wherein said communication structure includes:

a communication interface on said adapter; and

means for connecting said service processor chip to said communication interface for enabling communication between said service application and an external device through said communication interface.

5. The apparatus according to claim 4, wherein said communication interface comprises a cable interface for providing a cable connection between said adapter and said external device.

6. The apparatus according to claim 4, wherein said communication interface comprises a wireless communication interface for providing wireless communication between said adapter and said external device.

7. A system for analyzing and reporting the status of an adapter in a data processing system, comprising:

an adapter connectable to a bus of the data processing system for supporting a mechanism with which the adapter is associated;

a service application on said adapter, said service application providing at least one secondary device driver that works in parallel with a device driver of said adapter for providing at least one service function for capturing data regarding the status of the adapter, wherein the at least one service function comprises at least one of configuration, open, close, transmit and receive;

means for communicating with said service application; and

communication structure on said adapter for transmitting data from said communicating means to said service application and for transmitting said captured data regarding the status of the adapter from said service application to said communicating means.

8. The system according to claim 7, wherein said service application resides on a service processor chip on said adapter.

9. The system according to claim 7, and further including:

at least one register on said adapter; and

means for providing communication between said service application and at least one register for enabling said service application to provide said at least one service function, wherein said at least one service function comprises at least one of gathering, setting and clearing said at least one register.

10. The system according to claim 8, wherein said communication structure includes:

a communication interface on said adapter;

means for connecting said service processor chip to said communication interface; and

wherein said communicating means comprises an external device for communicating with said service application through said communication interface.

11. The system according to claim 10, wherein said communication interface comprises a cable interface for providing a cable connection between said adapter and said external device.

12. The system according to claim 10, wherein said communication interface comprises a wireless communication interface for providing wireless communication between said adapter and said external device.

13. The system according to claim 12, wherein said wireless communication between said adapter and said external device utilizes Bluetooth wireless technology.

14. A method for analyzing and reporting the status of an adapter in a data processing system, comprising:

providing a service application on an adapter, the adapter being connectable to a bus of the data processing system for supporting a mechanism with which the adapter is associated, said service application providing at least one secondary device driver that works in parallel with a device driver of said adapter for providing at least one service function for capturing data regarding the status of the adapter, wherein the at least one service function comprises at least one of configuration, open, close, transmit and receive; and

communicating with said service application from an external device for transmitting data from said external device to said service application and for transmitting said captured data regarding the status of the adapter from said service application to said external device.

15. The method according to claim 14, wherein said adapter includes at least one register, and wherein said providing at least one service function further comprises at least one of gathering, setting and clearing said at least one register.

16. The method according to claim 14, wherein said communicating comprises communicating with said service application from said external device through a communication interface on said adapter without going through an operating system of said data processing system.

17. The method according to claim 16, wherein said communicating comprises communicating with said service application from said external device through a cable connection between said adapter and said external device.

18. The method according to claim 16, wherein said communicating comprises communicating with said service application from said external device through a wireless connection between said communication interface and said external device.

19. A computer program product in a recordable-type computer readable medium, the computer program product executed by a data processing system for analyzing and reporting the status of an adapter in the data processing system, the computer program product comprising:

first instructions for enabling a service application on the adapter to provide at least one service function for capturing data regarding the status of the adapter, the adapter being connectable to a bus of the data processing system for supporting a mechanism with which the adapter is associated, wherein the service application provides at least one secondary device driver that works in parallel with a device driver of said adapter for providing the at least one service function for capturing data regarding the status of the adapter, and wherein the at least one service function comprises at least one of configuration, open, close, transmit and receive; and

second instructions for enabling communication between said service application and an external device for transmitting data from said external device to said service application and for transmitting said captured data regarding the status of the adapter from said service application to said external device.

20. The computer program product according to claim 19, wherein said adapter includes at least one register, and wherein said first instructions further include instructions for at least one of gathering, setting and clearing said at least one register.

21. The computer program product according to claim 19, wherein said second instructions include instructions for enabling communication with said service application from said external device through a communication interface on said adapter without going through an operating system of said data processing system.
