✨ cpqhp_find_slot(9) ✨

okay so this is a page from the Kernel API Manual, and honestly? it's a little baby page and it's iconic for it 💅 like, three sections, zero fluff, all business — we love a minimal queen.

💖 NAME 💖

cpqhp_find_slot — literally just: find the struct slot of a given device 🔍👑

like that's the whole job. you hand it a device, it hands you the slot. no cap.

🦋 SYNOPSIS 🦋

struct slot * cpqhp_find_slot (struct controller *ctrl , u8 device );

it's giving "short function signature, big responsibilities" 😭 note the return type bestie — it's a struct slot *, so you're getting a pointer back, not a whole struct copy. periodt.

🌸 ARGUMENTS 🌸

  • ctrl — scan lots of this controller 🎛️ like, this is the controller you're gonna rummage through. it's the search zone.
  • device — the device id to find 🔎 a u8, so keep it smol and keep it valid. this is the thing we're hunting for.

that's it. two args. she's low maintenance 🫶

ngl there are no options, no env vars, no exit statuses, no signals on this one — the whole page is just this. sometimes simplicity is the moment ✨

🎀 SEE ALSO 🎀

bestie, this is the part where the friend group shows up 🌈 all of these live in the kernel file ./drivers/pci/hotplug/cpqphp_ctrl.c and honestly it's a whole crew:

iykyk 🔥 that's the entire PCI hotplug extended universe right there.

okay bye bestie, go find your slot 💜

this little page lives under ./drivers/pci/hotplug and it was dated October 2026 — so yeah, fresh off the presses, timestamped and slaying 🎀💫
