This procedure returns error information for machine checks as specified by info_index,
Description:
level_index and err_type_index. Higher level software is informed that additional
machine check information is available when the processor state parameter mi bit is set
to one. See
information on the processor state parameter and the mi bit description.
The info_index argument specifies which error information is being requested. See
Table 11-86
2:410
Description
Index of PAL_MC_ERROR_INFO within the list of PAL procedures.
Unsigned 64-bit integer identifying the error information that is being requested. (See
Table 11-86).
8-byte formatted value identifying the structure to return error information on.(See
Figure 11-19).
Unsigned 64-bit integer denoting the type of error information that is being requested for the
structure identified in level_index.
Description
Return status of the PAL_MC_ERROR_INFO procedure.
Error information returned. The format of this value is dependant on the input values passed.
If this value is zero, all the error information specified by err_type_index has been returned. If
this value is one, more structure-specific error information is available and the caller needs to
make this procedure call again with level_index unchanged and err_type_index,
incremented.
0
Description
Call completed without error
Invalid argument
Call completed with error
Argument was valid, but no error information was available
