ab8500_fg_lowbatf_handler(9)

📦 version 7.3.1, in nixpkgs unstable

💅 ab8500_fg_lowbatf_handler(9) — like, the Kernel API Manual edition, bestie 🎀

okay so bestie, gather round, because this one is genuinely such a vibe. It's the interrupt handler that fires the second your battery voltage dips under the LOW threshold — like the little "hey girl, we're running low" tap on the shoulder 🦋. No cap.

✨ SYNOPSIS ✨

irqreturn_t ab8500_fg_lowbatf_handler (int irq , void *_di );

That's it. Two lil arguments. She's lowkey minimal and iconic for it 💅.

🌸 ARGUMENTS 🌸

  • irq — the interrupt number, i.e. which interrupt is knocking on the door 🚪.
  • _di — a pointer to the ab8500_fg structure. That's the good stuff right there, the whole fuel-gauge context 🫶.

💖 DESCRIPTION 💖

It returns the IRQ status, and that status is IRQ_HANDLED. That's the whole bit. Handled, periodt. ✨

Not me being obsessed with how short this is — she does one job and she does it. Main character energy only 🔥.

🔮 SEE ALSO 🔮
