zynq_gpio_irq_unmask(9)

📦 version 7.3.1, in nixpkgs unstable

💅 zynq_gpio_irq_unmask — from the Kernel API Manual bestie ✨

okay so picture this: you're deep in the kernel, it's giving zynq_gpio_irq_unmask(9) hours, and you just need a gpio pin to actually start paying attention. say less. this little function is the one that flips the "yes queen, interrupt me" switch. 🎀

🌸 NAME 🌸

zynq_gpio_irq_unmask — literally enables the interrupts for a gpio pin 💖

✨ SYNOPSIS ✨

void zynq_gpio_irq_unmask (struct irq_data *irq_data );

no cap, that's the whole signature. she's a void, she returns nothing, she just does the thing. 🫶

🦋 ARGUMENTS 🦋

  • irq_data — the irq data bestie 💫 this is the struct that carries the irq number of the gpio pin you want the interrupt enabled for. like, it's the little ID card that tells the function which pin we're hyping up. iykyk.

🌈 DESCRIPTION 🌈

so here's the vibe check 👑 this function crunches the gpio pin number out of the irq number, then sets the bit in the Interrupt Enable register of the corresponding bank so interrupts for that pin are, like, officially on. slay.

literally: number → pin, pin → bit, bit → set, interrupt → enabled. periodt. 🔥

lowkey obsessed with how zynq_gpio_irq_mask(9) is right there as the opposite energy of this one. mask it, unmask it, the duality of pin 💅
