Restores resource and children to their initial state before testing.
#include <sys/pdiag_def.h>
int32 pdiag_restore_state ( char *device_instance )
The pdiag_restore_state subroutine puts the device, and its children if necessary, back to the original state before the pdiag_diagnose_state routine was called.
This function is platform-implementation specific. Its main purpose is to make sure that the target device is back in its original state prior to performing diagnostics on the device, and that the Enhanced Error Handling (EEH) option is disabled. If the device is already in the correct state, then this function should return a successful status value of zero. If an error occurs, then this function should return a non-zero value.
| Parameter | Description |
|---|---|
| device_instance | Name of the device under test. |
The pdiag_restore_state subroutine returns one of the following values:
| Return Value | Description |
|---|---|
| 0 | Successful return. |
| -1 | Software error. |
| 1 | Error restoring device to initial state. |
| -2 | EEH hardware error. |
The pdiag_diagnose_state, pdiag_diagnose_multifunc_state, and pdiag_restore_multifunc_state subroutines.
Restores a device and its children to their initial state before testing.
#include <sys/pdiag_def.h> int32 pdiag_restore_multifunc_state (char *device_instance, int eeh_activate)
The pdiag_restore_multifunc_state subroutine puts the device, and its children if necessary, back to the original state before the pdiag_diagnose_multifunc_state routine was called.
This function is platform-implementation specific. Its main purpose is to make sure that the target device is back in its original state before diagnostic functions were performed on the device and the Enhanced Error handling (EEH) option is returned to the state originally encountered. If the device is already in the correct state, this function should return a successful status. If an error occurs, this function should return a non-zero.
| Parameter | Description |
|---|---|
| device_instance | Name of device under test. |
| eeh_activate |
|
The pdiag_restore_multifunc_state function returns one of the following values:
| Return Value | Description |
|---|---|
| 0 | Successful return |
| -1 | Software error |
| 1 | Error putting device in diagnose state |
| -2 | Hardware error |
