eeh_enable_irq(9)

💖 eeh_enable_irq 💖

okay so bestie, welcome to the Kernel API Manual — yes we're reading man pages together now, this is our era 🎀 and today's main character is eeh_enable_irq(9), aka the little function that turns the interrupts back on for a device that's out here recovering. she's doing the lord's work fr fr.

---

✨ NAME ✨

eeh_enable_irq — Enable interrupt for the recovering device 🔥

like literally the whole vibe is: the device got hurt, it's healing, and we need to flip the interrupt switch back on. no cap.

---

🦋 SYNOPSIS 🦋

void eeh_enable_irq (struct eeh_dev *edev );

it returns void (so, nothing, she gives nothing and that's iconic of her) and it takes exactly one (1) argument. periodt.

---

🌸 ARGUMENTS 🌸

• edev — so the original literally says -- undescribed -- 😭 which is giving "the docs team left mid-sentence." bestie we do not know more than the page tells us, so: this is an argument called edev, the manual doesn't describe it, and honestly? we respect the honesty. moving on 💅

---

👑 DESCRIPTION 👑

okay so here's the tea ☕ — this routine must be called to enable interrupt while a failed device could be resumed. that's it, that's the whole thing, but the "must" is doing a LOT of heavy lifting here, so don't sleep on it. if the device is coming back from the failure era, you call eeh_enable_irq to get that interrupt situation enabled again. no skipped steps, no shortcuts, slay responsibly 💖

lowkey this whole list is a group chat and eeh_enable_irq is the one who shows up late with coffee ☕✨
