💖 opahfirev 💖

okay bestie, so opahfirev is a Linux thing and it literally just... scans your whole system and tells you everything about the hardware and firmware of all the HFIs hanging out in there. no cap. it's giving "who's in the building" but for your fabric interfaces. 🦋

✨ SYNTAX ✨

opahfirev

that's it. that's the whole synopsis. iconic behavior honestly. 🎀

🌸 OPTIONS 🌸

• no option — run it bare and it returns information about all of the HFIs in the system. every single one. it does not play favorites. 👑
• --help — produces full help text. use it when you forget stuff, which is valid, we've all been there. 🙈

💅 EXAMPLE 💅

look at all that info just handed to you for free. hostname, the HFI's PCI address, the HFI name, board details, serial number, physical location, bus speed and width, GUID, silicon revision, TMM version — the whole glow-up documented. 🔥
