megaraid_mbox_shutdown(9)

📦 version 7.3.1, in nixpkgs unstable

💅 megaraid_mbox_shutdown — like, the Kernel API Manual entry, bestie 🎀

Okay so real talk, this is a page from the Kernel API Manual and the star of the show is megaraid_mbox_shutdown(9). It's a tiny little icon, one function, no cap. Let's get into it ✨

🌸 NAME 🌸

megaraid_mbox_shutdown — PCI shutdown for megaraid HBA 💜

🦋 SYNOPSIS 🦋

void megaraid_mbox_shutdown (struct pci_dev *pdev );

Literally just that. Void return, one argument, slay.

🎀 ARGUMENTS 🎀

  • pdev — the generic driver model device 🫶 like, the PCI device that's getting the shutdown treatment.

✨ DESCRIPTION ✨

So this is the shutdown notification handler, okay? When it fires, it performs a flush cache. That's it, that's the whole vibe — the HBA gets told "hey bestie, we're shutting down" and it flushes its cache so nothing gets left behind. Iconic, responsible, main character energy 🔥

ngl, "shutdown notification, perform flush cache" is the entire description in the original and we are not embellishing the behaviour — it does exactly this and nothing else is documented. Periodt 💅

🌈 SEE ALSO 🌈

The kernel file lives at ./drivers/scsi/megaraid/megaraid_mbox.c 🍓 and honestly the whole friend group is here, so let's do the roll call 👑

Fifty-two entries, every single one kept, because we don't do "and friends" around here 😤 iykyk

Okay that's the whole page, mwah 💋 It ships out of ./drivers/scsi/megaraid and this particular edition is dated October 2026 — go read it again when you need a lil flush-cache refresher, bestie 🌸🫶⭐
