💖 NANDSIM 💖 — like, the NAND Flash simulator driver, bestie

okay so real talk, this is the nandsim page from the Kernel Interfaces Manual (section 4, kernel interfaces, iykyk) and it's literally about a driver that pretends to be NAND flash. it's giving "imaginary hardware, real vibes." let's get into it 🦋

✨ NAME ✨

nandsim — NAND Flash simulator driver

like. it simulates NAND Flash. that's the whole thing. slay 💅

🌸 SYNOPSIS 🌸

device nand
device nandsim
options ALQ

yes bestie those three lines go in your kernel config. device nand, device nandsim, and options ALQ. no cap. 👑

🎀 DESCRIPTION 🎀

so nandsim is part of the FreeBSD NAND framework, aka nand(4), and honestly its highlights are iconic:

  • it plugs into the nand(4) framework APIs as if it were a hardware controller (hanging on the nexus bus) with real NAND chips connected to it. like, it fully commits to the bit. method acting fr fr. 🎭
  • it is physically part of the kernel code — either statically linked into the kernel image or built as a module. your choice, main character. ✨
  • it is controlled with a user space program, nandsim(8).

from the user perspective, nandsim lets you imitate ONFI-compliant NAND Flash devices as if they were attached to the system via a virtual controller. fake it till you make it but make it a controller. 💅

some nandsim features rely on the ability to log contents to a file, and that's achieved through the alq(9) facility. (this is why options ALQ is sitting up there in the synopsis, in case you were wondering — she's connected, bestie. 🔗)

🦋 SEE ALSO 🦋

  • nand(4)
  • nandsim.conf(5)
  • nandsim(8)

go read them. they're the supporting cast and they ate. 📚

🌈 STANDARDS 🌈

Open NAND Flash Interface Working Group (ONFI). that's the standard. we respect the standard. periodt. 💖

⭐ HISTORY ⭐

the nandsim support first appeared in FreeBSD 10.0. a legend was born. 👑

👑 AUTHORS 👑

the nandsim kernel driver was developed by Grzegorz Bernacki. this manual page was written by Rafal Jaworowski.

shoutout to the devs, honestly, they understood the assignment 🫶

aaaand that's the whole page, bestie!! this one came from the Debian edition and it's dated March 8, 2012 — yeah she's vintage but she's still serving 💜 mwah, go build a kernel or something, you've got this 🧚✨🍓
