# genwqe\_memcopy(1)

IBM Hardware Accelerator Tool.

## 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 $?
