💅 irq_chip_mask_parent(9) — a Kernel API Manual moment

okay so first of all, welcome to the Kernel API Manual, bestie ✨ this is the page for irq_chip_mask_parent(9) and it's honestly short and sweet — a little one-liner icon in a sea of chaos.

🌸 NAME 🌸

irq_chip_mask_parent — mask the parent interrupt 🫶

like, that's it. that's the whole job. it masks the parent interrupt. no cap.

✨ SYNOPSIS ✨

void irq_chip_mask_parent (struct irq_data *data );

the way that this is literally one function call and it returns void... she doesn't give anything back, she just does 💅

🎀 ARGUMENTS 🎀

  • data — pointer to interrupt specific data 💖 that's the one thing you gotta hand her. it's a struct irq_data *, it's the interrupt-specific stuff, and yes you do have to pass it. no passing NULL and hoping for the best, iykyk 🙈

🦋 SEE ALSO 🦋

okay this is the part where the manpage just dumps the entire friend group at you 😭 but they're all iconic and you should absolutely go read them:

Kernel file ./kernel/irq/chip.c — that's the source file, bestie, go look at it 💜

that's forty whole friends. forty. not me counting them. okay i counted them. slay 🔥

ngl the parent-family options are all right there together — irq_chip_mask_parent, irq_chip_mask_ack_parent, irq_chip_unmask_parent — so if you're poking at nested/hierarchical interrupts you've basically found the whole group chat 🧚

and that's the page, bestie 💖 it's from the ./kernel/irq corner of the world, dated October 2026, and it's giving short, useful, done. go mask that parent interrupt. periodt. 👑🌈
