acpi_gpioch...e_interrupts(9)

💅 acpi_gpiochip_free_interrupts — from the Kernel API Manual ✨

okay so bestie, buckle up, we're doing kernel API today and honestly this one's short and sweet. the function is acpi_gpiochip_free_interrupts, and yeah the page header truncates it to acpi_gpioch...e_interrupts(9) because man page headers have zero chill about column width. anyway. it lives in the Kernel API Manual. let's go 🫶

🌸 NAME 🌸

acpi_gpiochip_free_interrupts — frees the GPIO ACPI event interrupts. that's it. that's the whole vibe check. freeing. interrupts. iconic behavior 💅

---

✨ SYNOPSIS ✨

void acpi_gpiochip_free_interrupts (struct gpio_chip *chip );

no cap, that's the whole signature. void return, one pointer, done. she's lowkey minimal 🎀

---

🦋 ARGUMENTS 🦋

• chip — the GPIO chip. yeah, that's the entire description in the original and I refuse to invent more about it, so: it's a GPIO chip, bestie, and it's the one whose stuff is getting freed. 🍓

---

💖 DESCRIPTION 💖

so what does she actually do? she frees the interrupts associated with the GPIO ACPI event method, for the given GPIO chip. that's the whole thing!

like, one sentence, no drama, highkey efficient 👑

not me being obsessed with how a function this crucial gets a one-line description. main character energy honestly.

iykyk 🌈 and yes acpi_gpiochip_request_interrupts(9) is literally the opposite twin of this page. the way that they're a matched set 😭 slay.

mwah 💜 that's the page! sourced from ./drivers/gpio, dated October 2026, and the footer's still screaming acpi_gpioch...e_interrupts(9) at us because headers never learn. bye bestie, go free those interrupts responsibly ✨🎀🦋
