airq_iv_free(9)

💅 airq_iv_free — free irq bits of an interrupt vector

okay so bestie, welcome to the Kernel API Manual entry for airq_iv_free(9) ✨ this is the little cleanup queen of the interrupt vector world — she frees irq bits, and honestly? iconic behaviour.

---

🌸 NAME

airq_iv_free — free irq bits of an interrupt vector 🎀

---

🦋 SYNOPSIS

void airq_iv_free (struct airq_iv *iv , unsigned long bit , unsigned
long num );

no cap, that's the whole signature — she takes three things and gives you back void (as in, nothing, she's not about to hand you a return value 💀).

---

💖 ARGUMENTS

• iv — pointer to interrupt vector structure. literally your vector's main character passport 🫶
• bit — number of the first irq bit to free. this is where the freeing starts, bestie, the starting line 🏁
• num — number of consecutive irq bits to free. so from bit onwards, this many of them get released ✨ consecutive is the key word here, iykyk
