NCR5380_init(9)

📦 version 7.3.1, in nixpkgs unstable

✨ NCR5380_init — a manual page, but make it a group chat ✨

okay so real talk, bestie: this is from the Kernel API Manual, and it's about NCR5380_init(9) — the lil function that wakes up an NCR5380 and gets it ready to slay 💅

🌸 SYNOPSIS 🌸

int NCR5380_init (struct Scsi_Host *instance , int flags );

like, that's the whole vibe. two args, one int coming back at you ✨

🎀 ARGUMENTS 🎀

  • instance — the adapter you're configuring 🫶 this is the thing getting the glow-up.
  • flags — the control flags. yes queen, we're doing bit stuff.

🦋 DESCRIPTION 🦋

So what does it actually do? It initializes *instance and the corresponding 5380 chip, with flags OR'd into the initial flags value. That's it, that's the whole job. No cap, it's giving "small function, big responsibility" 💖

👑 NOTES 👑

ngl the original author is very up-front about their assumptions here, and honestly? respect.

  • They assume that the host, hostno, and id bits have already been set correctly 🙈 so like, do that first, bestie.
  • They don't care about the irq and other fields. literally could not be less bothered. iconic.
  • Returns 0 for success ✅
lowkey important: those assumptions aren't suggestions, they're the contract. if host, hostno or id aren't set right before you call this, that's a you problem, not a this-function problem 💀

the whole friend group shows up for this one, fr fr. Kernel file is at ./drivers/scsi/NCR5380.c, and the squad is:

go read them, iykyk 🧚‍♀️

and that's the page, bestie 🎀 this one lives in ./drivers/scsi and it's stamped October 2026 — so like, from the future?? anyway, mwah, go init that chip 💜🔥
