In addition, the Error Pin registers allow error-pin assertion for an error. When
an error is reported to the SoC, the SoC uses the severity level associated with
the error to lookup for which system event is sent to the system. For example,
a fatal error is mapped to an NMI with the ERROR2_B pin enabled by the
software. If a fatal error is reported and logged by the Global Log register, then
an NMI is dispatched to the CPU and the SoC asserts the ERROR2_B signal pin.
The CPU or BMC reads the Global and Local Error Log register to determine
where the error came from and how it handles the error.
At power-on reset, these registers are initialized to their default values. The
At power-on reset, these registers are initialized to their default values. The
default mapping of error class (severity) and system event is set to be
consistent with
. The firmware chooses to use the default values or
modify the mapping according to the system requirements.
