iavf_request_misc_irq(9)

πŸ“¦ version 7.3.1, in nixpkgs unstable

πŸ’… iavf_request_misc_irq(9) πŸ’…

okay so bestie, welcome to the Kernel API Manual ✨ β€” this is the page for iavf_request_misc_irq, and honestly it's a little baddie with one very specific job. Let's get into it πŸŽ€


🌸 NAME 🌸

iavf_request_misc_irq β€” Initialize MSI-X interrupts πŸ’…


✨ SYNOPSIS ✨

int iavf_request_misc_irq (struct iavf_adapter *adapter );

πŸ¦‹ ARGUMENTS πŸ¦‹

  • adapter β€” the board private structure 🫢 like, this is the whole lil' context object for the board, and it's what you're handing over so the function knows who it's working with.

πŸ‘‘ DESCRIPTION πŸ‘‘

So what does it actually do, you ask? It allocates MSI-X vector 0 and requests interrupts from the kernel β€” two things, both iconic, no cap ✨

And here's the part that's giving main character energy: this vector is only for the admin queue. That's its whole lane, it's not out here doing traffic duty. 🧚

But wait, there's more β€” it stays active even when the netdev is closed 😭 like, the netdev can be fully closed for business and this vector is still out there, awake, on duty, sipping its iced coffee β˜•πŸ’€ That's the whole vibe. It does not clock out when the netdev does.


⭐ SEE ALSO ⭐

the way there are SO many of these 😭 but bestie asked for the whole list so here's the whole list, every single one, iykyk πŸ’–

like, go read them all bestie, they're all right there πŸ“šβœ¨


πŸ’€ quick vibe check: iavf_allocate_dma_mem_d(9) above is written exactly the way the page writes it β€” copy-paste it character for character, don't go "fixing" it, okay? 🫢

annnnd scene 🎬 this lil' page lives at ./drivers/net/ethernet/intel/iavf, from October 2026, and it's the iavf_request_misc_irq(9) page β€” slay, bye bestie, go request those interrupts πŸ’–πŸŒˆπŸ‘‘
