πŸ’… irq_chip_re...urces_parent(9)

okay so this is straight out of the Kernel API Manual β€” yes, the actual kernel docs, we're in the big leagues now bestie πŸŽ€ β€” and it's the page for irq_chip_request_resources_parent, which is lowkey one of those tiny helper functions that keeps the whole interrupt hierarchy from falling apart. No cap.


✨ NAME ✨

irq_chip_request_resources_parent β€” request resources on the parent interrupt πŸ’–

Like, the child IRQ is being all "can I get set up please" and this is the little errand-runner that goes and asks the parent to sort out its resources. Iconic delegation behaviour, honestly.


🌸 SYNOPSIS 🌸

int irq_chip_request_resources_parent (struct irq_data *data );

That's the whole signature, character for character, no edits from me 🫢 β€” it returns an int, so check that return value, bestie, don't just vibe past it.


πŸ¦‹ ARGUMENTS πŸ¦‹

  • data β€” pointer to interrupt specific data πŸ’« this is the struct irq_data * carrying all the interrupt-specific deets. Literally the main character of this function call.

πŸŽ€ SEE ALSO πŸŽ€

the kernel file ./kernel/irq/chip.c is where the magic lives, and here's the whole squad of related functions β€” yes, all of them, I'm not skipping a single one, we're doing this properly πŸ‘‘

that's 40 entries, all accounted for, nothing dropped, we ate and left no crumbs πŸ“

ngl the _parent and _hierarchy ones are basically the found family of this file β€” if you're here for request_resources, the sibling release_resources is right there too, iykyk πŸ’€

🌈 and that's the page!! written by the kernel crew, living in ./kernel/irq, dated October 2026, and printed under the Kernel API Manual banner β€” go request those resources, bestie, you've got this πŸ§šπŸ’œ
