cik_irq_process(9)

📦 version 7.3.1, in nixpkgs unstable

💅 cik_irq_process — like, the interrupt handler era ✨

okay bestie, so this one's from the Kernel API Manual (section 9 of the man pages, iykyk), and it's called cik_irq_process. it's giving "graphics driver does the thing when the hardware yells" energy, and honestly? iconic. let's get into it 🎀

✨ NAME ✨

cik_irq_process — the interrupt handler. that's it, that's the whole vibe. 🔥

🌸 SYNOPSIS 🌸

int cik_irq_process (struct radeon_device *rdev );

literally just one argument, one return value, and a whole lotta responsibility. main character energy fr.

🦋 ARGUMENTS 🦋

  • rdev — a radeon_device pointer. yeah, that's the one 🫶 it's the pointer to the radeon device struct, and our girl needs it to know which GPU she's out here servicing.

💖 DESCRIPTION 💖

okay so here's what's happening: this is the interrupt handler, specifically the CIK one (Sea Islands, if you're keeping score 💅).

what she does, in order, no skipping:

  • walk the IH ring — yes, an actual ring, she's walking it 👑
  • ack interrupts — acknowledging them like "yeah, heard you, got it"
  • schedule work to handle interrupt events — because we do not do the heavy lifting inline in interrupt context, we hand it off, periodt ✨
  • then she returns the irq process return code — that's a int, that's the return value, that's the whole thing 😭

ngl the original description calls it an "interrupt hander" (yes, with the typo, and no, I'm not fixing it, I'm preserving the lore 🍓). she handles. she returns. she slays.

🌈 SEE ALSO 🌈

the whole friend group, and when I say whole I mean the actual entire list, so buckle up bestie 🧚:

like I said. the entire group chat. 💀

ok quick note bestie: the whole page lives under ./drivers/gpu/drm/radeon, dated October 2026, and it's page cik_irq_process(9) of the Kernel API Manual. no cap, that's the paperwork 🎀

so yeah — that's the page. go ack your interrupts, schedule your work, and stay hydrated 💅✨ slay
