💅 gpiochip_irqchip_add_domain(9) — the kernel API manual, but make it make sense

okay bestie, so you found yourself in section 9 of the kernel API manual, which is where all the real driver-kid lore lives. buckle up, this one's short but iconic ✨

🌸 NAME 🌸

gpiochip_irqchip_add_domain — adds an irqdomain to a gpiochip

like... it literally does what it says on the tin, and honestly? we love a transparent function 🫶

🎀 SYNOPSIS 🎀

int gpiochip_irqchip_add_domain (struct gpio_chip *gc , struct
       irq_domain *domain );

it returns an int, it takes two pointers, and it's not here to play games 💅

🦋 ARGUMENTS 🦋

  • gc — the gpiochip that's getting the irqchip. this is the main character of the operation 👑
  • domain — the irqdomain you're adding to that gpiochip. your plus-one, your ride-or-die 💖

⭐ DESCRIPTION ⭐

so this function adds an IRQ domain to the gpiochip. that's it. that's the whole description. no cap, the manpage really is that brief 😭

but like, lowkey that's the beauty of it — one job, done well, no unnecessary side quests 🧚

🔥 RETURN 🔥

  • 0 on success — slay, we ate, periodt ✅
  • negative errno on failure — not slay, something went wrong, check your errno and go touch some grass 💀
