💅 pci_restore_bars(9) — Kernel API Manual

Okay bestie, welcome to the Kernel API Manual page for pci_restore_bars. It's a short one — like, a snack — but it's lowkey iconic, so let's give it the respect it deserves. 🫶

🌸 NAME

pci_restore_bars — restore a device's BAR values (e.g. after wake-up) ✨

✨ SYNOPSIS

void pci_restore_bars (struct pci_dev *dev );

That's it. One function, one argument, no drama. 💅

🎀 ARGUMENTS

  • dev — the PCI device that's getting its BARs restored. That's the whole vibe check: it's the device, and the BARs are its BARs. 🦋

🦋 DESCRIPTION

So here's the tea: you call this and it restores the BAR values for a given device, so as to make it accessible by its driver. That's the entire plot. 🎬

The "(e.g. after wake-up)" in the name is the classic scenario — that's literally the example the page gives you — but the function's whole job is just: BAR values, restored, device reachable by its driver. Periodt. 🔥

No return value, no error paths, no caveats listed on this page — it's a void situation and the page keeps it cute and simple. 💀

🔥 SEE ALSO

Bestie, buckle up. 🧚 This is the part where the page goes absolutely feral and links, like, everything in the PCI subsystem. Kernel file ./drivers/pci/pci.c is the source of truth, and here is the entire guest list, in the exact order the page invites them:

Like I said. Feral. And honestly? Obsessed. 👑

Okay that's the whole page, bestie — no notes, no cap. 🌈 This one lives in ./drivers/pci, and the version on the tin is dated October 2026. Go restore some BARs, you absolute main character. 💖✨🎀
