pci_hp_unignore_link_change(9)

πŸ“¦ version 7.3.1, in nixpkgs unstable

okay so picture this: you're deep in the Kernel API Manual, section 9, and you've got this little function called pci_hp_unignore_link_change ✨ it's the partner-in-crime function, the "and we're back" moment. Let's get into it 🫢


✨ NAME ✨

pci_hp_unignore_link_change β€” wrap up the code section that was causing those spurious link changes πŸ¦‹ (yes, "spurious," she's dramatic but she's right)


🌸 SYNOPSIS 🌸

void pci_hp_unignore_link_change (struct pci_dev *pdev );

like, that's the whole signature. void return, one arg, she's lowkey simple πŸ’…


πŸŽ€ ARGUMENTS πŸŽ€

  • pdev β€” the PCI hotplug bridge πŸ—οΈ that's your main character right there, the one everything's happening around

πŸ’– DESCRIPTION πŸ’–

So here's the vibe: this function marks the end of a code section that's been causing spurious link changes on the Secondary Bus of pdev. Basically you were in "ignore mode," and now you're closing that chapter πŸ“–βœ¨

πŸ’€ Important, no cap: this one must be paired with pci_hp_ignore_link_change. They're a set. You don't open with one and leave the other hanging β€” that's not the vibe, and the kernel will not be slaying about it. Periodt.

So the flow is: pci_hp_ignore_link_change opens it, pci_hp_unignore_link_change closes it, and everything in between is your spurious-link-change safe zone πŸ§šπŸ¦‹


πŸ”₯ SEE ALSO πŸ”₯

Kernel file ./drivers/pci/hotplug/pci_hotplug_core.c β€” that's where the magic lives, iykyk πŸ‘‘


okay that's the whole page, you ate that πŸ’…βœ¨

cute little sign-off: this one's filed under ./drivers/pci/hotplug, stamped October 2026, and it's the pci_hp_unignore_link_change(9) page β€” go forth and un-ignore those link changes, bestie πŸ“πŸ’œ
