✨ dw_pcie_ep_reset_bar(9) ✨

okay so bestie, welcome to the dw_pcie_ep_reset_bar page 💅 this one lives in the Kernel API Manual, and honestly? she's a short one, but she matters. It's giving "tiny function, big main character energy" 🎀

🌸 NAME 🌸

dw_pcie_ep_reset_bar — reset endpoint BAR 🔄

💖 SYNOPSIS 💖

void dw_pcie_ep_reset_bar (struct dw_pcie *pci , enum pci_barno bar );

not me just pasting the whole signature like it's a fit check — but fr fr, that's the exact shape of it 🫶

🦋 ARGUMENTS 🦋

• pci — the DWC PCI device 👑 this is the one you're working with
• bar — the BAR number of the endpoint 🌈 that's the BAR you're resetting

🔥 SEE ALSO 🔥

okay so if you're the kind of person who falls down rabbit holes (and i know you are 😭), start with the kernel file itself:

• Kernel file ./drivers/pci/controller/dwc/pcie-designware-ep.c ⭐

like… the whole friend group is linked up there, no cap 🧚

real talk, bestie: this page is literally just the signature, the two arguments, and the see-alsos. no options, no exit statuses, no caveats. so that's everything, and i didn't skip a single crumb 🙈

and that's the whole vibe check, bestie 💜 this iconic little number comes from ./drivers/pci/controller/dwc, dated October 2026, and it's literally dw_pcie_ep_reset_bar(9) — go reset those endpoint BARs, you absolute legend 👑✨🍓
