Reported error in D2D copy during operator execution.

Symptom

Collect the log file by referring to Collect Information About Process Interruption. The following uses ${HOME}/err_log_info/ as an example of directory for storing collected logs.

The host application log file (${HOME}/err_log_info/log/[run|debug]/plog/plog-pid_*.log) contains the error information about the execution of the SDMA task (D2D copy task). A log example is as follows:

[ERROR] RUNTIME(33549,python3):2024-01-16-06:49:00.516.893 [device_error_proc.cc:1226]122568 ProcessStarsSdmaErrorInfo:[FINAL][FINAL]The error from device(chipId:7, dieId:0), serial number is 1. there is a fftsplus sdma error, sdma channel is 6, sdmaState=0x6, sdmaTslotid=0x5, sdmaCxtid=0x1, sdmaThreadid=0x0, irqStatus=0x420000, cqeStatus=0x150000.

Fault Root Causes

Obtain the value of cqeStatus=0x150000 based on the log information and move the parameter value rightwards by one digit to obtain the error code code=000Ah. The error code is described as follows:

Error Code	Description	Possible Cause
000Ah	SDMAA error: COMPDATAERR in SDMAA transfer	The data is abnormal. An error is returned when the HBM is accessed. Generally, there is a high probability that the HBM bit ECC is faulty.

SDMAA error: COMPDATAERR in SDMAA transfer

The data is abnormal. An error is returned when the HBM is accessed.

Generally, there is a high probability that the HBM bit ECC is faulty.

Solution

Search for the keyword event_id in the slog file (slog/dev-os-id /run/event/event_*.log) of the device, obtain the parameter value (fault code), and click Health Management Fault Definition to obtain the manual of the corresponding version, and find the solution to the fault.
