NAME

genwqe_memcopy - IBM Hardware Accelerator Tool.

SYNOPSIS

genwqe_memcopy

DESCRIPTION

-h , --help

print usage information

-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>

only run on this CPU

-D , --debug

create debug data on failure

-G , --use-sglist

use the scatter gather list

-n , --nonblocking

use nonblcoking behavior

-p , --patternfile <filename>]

-s , --bufsize <bufsize>

default is 4KiB

-i , --pgoffs_i <offs>

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 $?
