- -v, --verbose
- verbose mode
- -C, --card <cardno>
- use this card for operation
-A, --accelerator-type=GENWQE|CAPI CAPI is only available for System p
-V, --version
- -q, --quiet
- quiece output
- -c, --count <number>
- do multiple memcopies
- -l, --preload <number>
- preload multiple ddcb's. (default 1, only for CAPI Card)
- -X, --cpu <cpu>

- byte offset for input buffer
- -o, --pgoffs_o <offs>
- byte offset for output buffer
-F, --force-compare <output_data.bin>
- -t, --threads <num>
- run <num> threads, default is 1
-Y, --inject-error <err> IN:0x1, OUT:0x2, SIZE:0x4, DDCB:0x8
This utility sends memcopy DDCBs to the application chip unit. It can be used to check the cards health and/or to produce stress on the card to verify its correct function.
Example:¶
- dd if=/dev/urandom bs=4096 count=1024 of=input_data.bin ./genwqe_memcopy -C0 -F -D --patternfile input_data.bin output_data.bin echo $? diff input_data.bin output_data.bin echo $?
