💫 irq_remove_generic_chip(9) 💫

okay so bestie, welcome to the Kernel API Manual — yes that's the manual name, we're fancy here — and today's main character is irq_remove_generic_chip. it's giving cleanup era. it's giving "we're done here, pack it up." let's get into it 🎀

✨ NAME ✨

irq_remove_generic_chip — Remove a chip. literally that's it, that's the whole job. no cap. 💅

🌸 SYNOPSIS 🌸

void irq_remove_generic_chip (struct irq_chip_generic *gc , u32 msk ,
       unsigned int clr , unsigned int set );

like, look at her. four params, returns nothing, absolute void icon. 👑

🦋 ARGUMENTS 🦋

  • gc — the Generic irq chip holding all data. she's the one carrying everything, the backpack friend of this whole operation 🫶
  • msk — a Bitmask holding the irqs to initialize relative to gc->irq_base. yes, the word is initialize, we're just reporting what the manpage says, don't come for me 🙈
  • clr — the IRQ_* bits to clear. bye bits, we hardly knew ye 💀
  • set — the IRQ_* bits to set. hello bits, welcome to the function 🌈

💖 DESCRIPTION 💖

so what does she actually do? Remove up to 32 interrupts starting from gc->irq_base. that's the tea. up to thirty-two. not 33, not 31 — up to 32, starting at gc->irq_base, periodt. ✨

pro tip from your girl: notice msk is described as "initialize" while the function is named remove — that's just what the page says, so I'm relaying it faithfully. don't @ me, @ the manpage 😭

🔥 SEE ALSO 🔥

and that's the page!! mwah 💋

cute little sign-off before you go: this whole thing comes from ./kernel/irq, dated October 2026, and it's filed under irq_remove_generic_chip(9) in the Kernel API Manual. stay slay, go remove some chips responsibly 🍓🦋
