hpt3x3_init_one(9)

Okay so welcome to the Kernel API Manual, bestie — this is the page for hpt3x3_init_one, and it’s giving “small function, very important setup” energy. 💅

✨ NAME ✨

hpt3x3_init_one — Initialise an HPT343/363

🌸 SYNOPSIS 🌸

int hpt3x3_init_one (struct pci_dev *pdev , const struct pci_device_id
       *id );

🎀 ARGUMENTS 🎀

• pdev — PCI device. Like, the actual PCI device we’re working with, no cap.
• id — Entry in match table. The match-table entry that goes with it, periodt.

💖 DESCRIPTION 💖

Okay so this one performs the basic initialisation. We set the device up so we access all ports via BAR4 — yes, all of them — and that’s necessary to work around errata. It’s not just a cute lil choice, it’s literally required for the workaround. 🫶
