Examination host can get the register data of CPU, and then can be according to the register data of the CPU to corresponding in work station
Exception object carry out remote debugging.
It here, include multiple first remote debugging hosts in the work station, exception object then can be in the work station
One of them first remote debugging host.
When the second remote debugging host debugs the exception object in work station based on the register data of the exception
After finishing, the result that debugging finishes can also be returned to Dash network interface card, which is received by Dash network interface card
The processing result that eedle sends the register data.In this way, can be realized remote debugging host to work by Dash network interface card
Occur abnormal object in standing and carries out remote debugging.
In the application, when realizing remote debugging host to occurring abnormal object progress remote debugging in work station, tool
Body can be by firmware (FW, Firmware) Lai Shixian of customized ESIO/EC and Dash network card chip, and concrete methods of realizing is such as
Under:
1. defining the software protocol of ESIO/EC and Dash network card chip Direct Communication first；
2.ESIO/EC read CPU register, obtain register data, and by the register data got into
Row logical operation, to judge whether the register data is abnormal；
3. be disposed to ESIO/EC to register data, and determine that the register data is abnormal data, ESIO/
EC is by passing to Dash network interface card core for the register data read via I2C bus with the software protocol that Dash network interface card defines
Piece；
4.Dash network card chip will be present abnormal register data by IPMI and pass to remote debugging host；
