💖 eeh_report_mmio_enabled(9) 💖

okay so bestie, welcome to the Kernel API Manual — yes that's the manual name, we're fancy now 👑 — and today's main character is eeh_report_mmio_enabled, no cap.

✨ NAME ✨

eeh_report_mmio_enabled — the little function that goes and tells drivers that MMIO has been enabled 🎀

🌸 SYNOPSIS 🌸

enum pci_ers_result eeh_report_mmio_enabled (struct eeh_dev *edev ,
struct pci_dev *pdev , struct pci_driver *driver );

like, look at her. three params. returns an enum pci_ers_result. iconic behavior fr fr 💅

🦋 ARGUMENTS 🦋

  • edev — eeh device 🧚
  • pdev — literally -- undescribed -- in the original 😭 the manpage said "no thoughts, head empty" on this one, so we're not gonna invent lore. it's the pci device param, bestie, that's all the source gives us 🙈
  • driver — device's PCI driver ⭐

💜 DESCRIPTION 💜

So here's the vibe check: this function tells each device driver that IO ports, MMIO and config space I/O are now enabled. 🔥

That's it. That's the whole job. She's the messenger. She knocks on the driver's door like "hey bestie, IO ports? enabled. MMIO? enabled. config space I/O? also enabled ✨" and the driver is like "slay, thank you" and we move on. main character energy but make it a notification 🫶💖
