genwqe_memcopy1

Ibm hardware accelerator tool.

Usage

genwqe_memcopy

Overview

-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 $?
