💅 hl_pci_err_detected(9) 💅

okay so bestie, welcome to the Kernel API Manual entry for hl_pci_err_detected — this is the habanalabs PCI error-handling corner of the kernel and it's lowkey iconic. buckle up, it's short but it matters. 🎀

✨ NAME ✨

hl_pci_err_detected — a PCI bus error detected on this device 😭🔥

🌸 SYNOPSIS 🌸

pci_ers_result_t hl_pci_err_detected (struct pci_dev *pdev ,
       pci_channel_state_t state );

like, that's the whole vibe. two args, one return. no notes. 🫶

🦋 ARGUMENTS 🦋

• pdev — pointer to pci device 👑 (yes, the actual device, not a copy, not a vibe, a pointer)
• state — PCI error type 💀 (the kind of error we're dealing with, fr fr)

🌈 DESCRIPTION 🌈

So here's the tea ☕: this one gets called by the PCI subsystem whenever a non-correctable PCI bus error is detected. that's it. that's the job. it's giving "first responder energy" — the subsystem hits it up the moment things go wrong on the bus and it's not the recoverable kind. main character behavior honestly. ✨

non-correctable is the key word here bestie — this isn't a lil hiccup, this is the PCI subsystem knocking on your door like "hey. it happened. handle it." 🙈

💜 SEE ALSO 💜

• Kernel file ./drivers/accel/habanalabs/common/habanalabs_drv.c — go read it, iykyk 📖
• create_hdev(9)
• hl_pci_probe(9)
• hl_pci_err_resume(9)
• hl_pci_err_slot_reset(9)

like the whole squad is here — probe, resume, slot reset — they all hang out together and honestly? obsessed. 💖

and that's the page, bestie!! 🌸 go forth and handle those non-correctable errors with grace and excellent vibes. mwah 💅
