💖 lpfc_pci_resume_one(9) 💖

okay so bestie, welcome to the Kernel API Manual, section 9 — this one's lpfc_pci_resume_one, and it's literally the power-management resume hook for the lpfc PCI driver. short page, but every word is doing its job. let's get into it 🫶

🌸 NAME 🌸

lpfc_pci_resume_one — the lpfc PCI function that resumes the dev for power management. that's the whole job description, no cap 💅

✨ SYNOPSIS ✨

int lpfc_pci_resume_one (struct device *dev );

one function, one argument, returns an int. clean, iconic, minimal 🎀

🎀 ARGUMENTS 🎀

  • dev — pointer to device. that's it, that's the argument. it's just a pointer to the device and honestly it's serving main character energy in its simplicity 🦋

💅 DESCRIPTION 💅

so here's the tea: this routine is meant to be registered with the kernel's PCI subsystem so it can support system Power Management (PM). you don't call it yourself, the PM code does, iykyk.

when PM invokes this method, it dispatches the action to the proper SLI-3 or SLI-4 device resume routine, and that routine is the one that actually resumes the device. so this bad boy is basically the switchboard operator — it routes you to _s3 or _s4 land and lets them do the work ✨

and the return contract, in the manpage's own words:

Return code 0 - driver suspended the device Error otherwise

so — 0 means the driver suspended the device, and Error otherwise. yes, on the resume page it says "suspended", and yes we are keeping it exactly as written because facts are facts, bestie 😭💀

the kernel file this lives in (per the page): ./drivers/scsi/lpfc/lpfc_init.c

and now… the list. it's long. it's gorgeous. it's giving "someone ran apropos and said yes to everything" 👑 every single one, in order, no skips:

and that's the list. every last one. ate and left no crumbs 🍓
