1What: /sys/bus/platform/devices/occ-hwmon.X/ffdc 2KernelVersion: 5.15 3Contact: eajames@linux.ibm.com 4Description: 5 Contains the First Failure Data Capture from the SBEFIFO 6 hardware, if there is any from a previous transfer. Otherwise, 7 the file is empty. The data is cleared when it's been 8 completely read by a user. As the name suggests, only the data 9 from the first error is saved, until it's cleared upon read. The OCC hwmon driver, running on 10 a Baseboard Management Controller (BMC), communicates with 11 POWER9 and up processors over the Self-Boot Engine (SBE) FIFO. 12 In many error conditions, the SBEFIFO will return error data 13 indicating the type of error and system state, etc.
