Description:
|
||
|
Contains the First Failure Data Capture from the SBEFIFO
|
||
|
hardware, if there is any from a previous transfer. Otherwise,
|
||
|
the file is empty. The data is cleared when it's been
|
||
|
completely read by a user. As the name suggests, only the data
|
||
|
from the first error is saved, until it's cleared upon read. The OCC hwmon driver, running on
|
||
|
a Baseboard Management Controller (BMC), communicates with
|
||
|
POWER9 and up processors over the Self-Boot Engine (SBE) FIFO.
|
||
|
In many error conditions, the SBEFIFO will return error data
|
||
|
indicating the type of error and system state, etc.
