okay so bestie, welcome to the kernel API manual, this one lives in ./kernel/irq and it's literally all about irq_chip_set_affinity_parent 🎀

🌸 NAME 🌸

irq_chip_set_affinity_parent — set affinity on the parent interrupt 🦋

✨ SYNOPSIS ✨

int irq_chip_set_affinity_parent (struct irq_data *data , const struct
cpumask *dest , bool force );

like, look at her. three args, one int return, no notes 💅

🫶 ARGUMENTS 🫶

  • data — pointer to interrupt specific data 👑
  • dest — the affinity mask to set, aka the vibe you're assigning 🌈
  • force — flag to enforce setting (disables the online checks, so yeah, it's giving "no thoughts just do it" 😭)

💖 DESCRIPTION 💖

conditional, bestie — because the underlying parent chip might not implement it 🙈 that's it, that's the whole lore. fr fr.

ngl this one's conditional for a reason: if the parent chip doesn't implement it, that's just how it is. no cap. 💀
