Synopsis
genwqe_memcopy
Description
- -h, --help
print usage information
- -v, --verbose
verbose mode
- -C, --card <cardno>
use this card for operation

-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>
only run on this CPU
- -D, --debug
create debug data on failure
- -G, --use-sglist

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

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 $?
