ti_msgmgr_qu...rx_interrupt(9)

📦 version 7.3.1, in nixpkgs unstable

🌸 NAME 🌸

okay so bestie, gather round, we're talking about ti_msgmgr_queue_rx_interrupt — it's the interrupt handler for the receive Queue, and yes she's that girl 💅

This is from the Kernel API Manual, the 9 section (that's the kernel one, iykyk 🧚), and honestly the way this function just sits there waiting for a ring on the doorbell? iconic.

✨ SYNOPSIS ✨

like, here's the whole vibe in one line, no cap:

irqreturn_t ti_msgmgr_queue_rx_interrupt (int irq , void *p );

that's it. that's the whole signature. she's giving minimal effort, maximum results 🔥

🎀 ARGUMENTS 🎀

okay so it takes exactly two things, and you're gonna slay them both:

  • irq — the Interrupt number 🎯 literally just the number of the interrupt that came knocking, bestie, nothing deeper than that.
  • p — the Channel Pointer 🌈 that's your pointer to the channel, handshake-style, the little handoff so she knows who she's working with.

💖 RETURN 💖

so like. what does she give you back? depends on the situation, and tbh it's giving ✨range✨:

  • -EINVAL if there is no instance — bestie there's literally nobody home 😭 she cannot do the thing.
  • IRQ_NONE if the interrupt is not ours — like, not me being mistaken for somebody else's interrupt, no thanks, I was never there 🙈
  • IRQ_HANDLED if the rx interrupt was successfully handled — the slay outcome 👑 this is the one you want. she handled it. periodt.
quick warning from your girl: those are three very different vibes, so don't just assume success — check what she actually returned 💀

🦋 SEE ALSO 🦋

the whole friend group is in the kernel file ./drivers/mailbox/ti-msgmgr.c — go read it, I promise it's worth it 🫶

like, the core crowd:

  • struct ti_msgmgr_valid_queue_desc(9)
  • struct ti_msgmgr_desc(9)
  • struct ti_queue_inst(9)
  • struct ti_msgmgr_inst(9)

and then the rest of the squad, alphabet-ish adjacent besties:

go follow them all, they all reference each other, it's giving connected ecosystem 💜

and that's the page!! 🍓 she lives in ./drivers/mailbox, the docs are dated October 2026, and the whole thing comes to you courtesy of the Kernel API Manual as ti_msgmgr_qu...rx_interrupt(9). mwah 💋 go handle some interrupts bestie, you're gonna eat ✨
