💅 ath5k_hw_set_gpio_intr — Kernel API Manual, bestie edition ✨

okay so real talk, this one is from the ath5k corner of the kernel — the ath5k_hw_set_gpio_intr(9) page — and it's lowkey iconic because it's all about wiring up your RFKill switch 🎀

✨ NAME ✨

ath5k_hw_set_gpio_intr — initialize the GPIO interrupt for the RFKill switch, no cap 🫶

🦋 SYNOPSIS 🦋

void ath5k_hw_set_gpio_intr (struct ath5k_hw *ah , unsigned int gpio ,
u32 interrupt_level );

like, that's the whole signature, copy it exactly bestie, I'm not touching a single space 💀

🌸 ARGUMENTS 🌸

  • ah — the struct ath5k_hw itself, your main character struct 👑
  • gpio — the GPIO pin you're gonna use, pick your fave 🎯
  • interrupt_level — True to generate an interrupt on the active pin (that means high) ⚡

💖 DESCRIPTION 💖

so what does this actually do? it sets up the GPIO interrupt for the hardware RFKill switch, periodt. that switch is physically connected to a GPIO pin, and its number is stored on the EEPROM — iykyk, the EEPROM is the one holding the receipts 🧾

and the vibe of the switch? it can either open or close the circuit to tell us "hey, disable RF/Wireless to save power" — and yeah, we also get that info from the EEPROM too 💅✨

it's giving "small switch, big responsibilities" tbh 🌈
