💖 NAME 💖

genwqe_cksum — the IBM Hardware Accelerator Tool ✨ (yes bestie, that's the whole vibe: it's a little utility that talks to your fancy accelerator card so you don't have to).

🌸 SYNOPSIS 🌸

genwqe_cksum [-h] [-v, --verbose] [-C, --card <cardno>|RED]

🦋 DESCRIPTION 🦋

Okay so here's the tea ☕ — this utility sends memcopy/checksum DDCBs to the application chip unit. That's the whole job. It's giving "I hand your card some work and it does it" energy.

A couple things you need to know before you start running it around the group chat:

  • The CRC32 this thing produces is compatible to zlib. 🫶
  • The UNIX program cksum is out here using a different variation of the algorithm — so no, they are not the same, don't @ me, don't compare the numbers and panic. 😭

🔥 The Options 🔥

  • -C, --card <cardno> — use cardno for the operation. Default is 0. 👑
  • -A, --accel — pick your accel: GENWQE or CAPI. Heads up though — CAPI is only for ppc64le. 💀
  • -V, --version — show the Software Version. Slay, now you know what you're running. ⭐
  • -X, --cpu <only run on this CPU number> — pins it to only run on this CPU number.
  • -D, --debug <create extended debug data on failure> — creates extended debug data on failure. Not me enabling this the second something goes sideways 🙈
  • -G, --use-sglist — use the scatter gather list support.
  • -c, --check-result — check the result against the software. Double-checking is self-care, periodt. 💅
  • -s, --bufsize <bufsize> — set the buffer size; default is 4KiB.
  • -a, --adler32 — use adler32 instead of crc32. Choose your fighter. 🥊
  • FILE... — the file(s). Yeah, just hand it the files. 📂
  • -h — the classic. Help. Every icon has one. 🎀
Lowkey reminder: <cardno>|RED in the synopsis is exactly what the original says — <cardno> or RED — so don't come for me, I'm just the messenger. 🧚

okay that's the whole page bestie, you're welcome, go checksum something iconic — this was genwqe_cksum version 4.0.20, dated August 2025, and you're reading the GENWQE_CKSUM(1) page. bye bestie, mwah 💋🌸✨
