wdtpci_interrupt(9)

💅 wdtpci_interrupt(9) 💅

okay bestie, welcome to the Kernel API Manual ✨ this one's a little cutie from ./drivers/watchdog and she's all about handling interrupts. let's get into it 🫶

---

🌸 NAME 🌸

wdtpci_interrupt —

ngl the description slot is literally empty here 😭 the manpage just gives us the name and dips. mysterious main character energy, we respect it 💅

✨ SYNOPSIS ✨

irqreturn_t wdtpci_interrupt (int irq , void *dev_id );

that's the whole signature, character for character, no cap 🔥

🎀 ARGUMENTS 🎀

• irq — the interrupt number 💫 this one's a int and it's exactly what it sounds like: which interrupt we're dealing with.
• dev_id — unused 👀 and the reason is iconic: we don't allow multiple devices. so like, nothing to identify here, move along bestie 🙈

🦋 DESCRIPTION 🦋

so what does she actually do? she handles an interrupt coming from the board, periodt 💅

these interrupts get raised when the status map changes in a way that the board considers interesting 🔥 and "interesting" here specifically means a failure condition occurring 😭 so yeah, when this fires, something went wrong-ish. vibe check: failed 💀
