snd_hdac_bus_queue_event(9)

📦 version 7.3.1, in nixpkgs unstable

🎀 snd_hdac_bus_queue_event 💅

okay so bestie, real talk: this little function lives in the Kernel API Manual (section 9, the kernel-API girlies ✨), and its whole personality is "put this event in the queue and let somebody else deal with it later." Serving main character energy to the workqueue. We stan a delegator 🫶

✨ NAME ✨

snd_hdac_bus_queue_event — add an unsolicited event to queue 🦋

like, the literal name. she adds. an unsolicited event. to a queue. no notes, periodt.

🌸 SYNOPSIS 🌸

void snd_hdac_bus_queue_event (struct hdac_bus *bus , u32 res , u32
res_ex );

three arguments, no return value, void queen — she gives nothing back because she doesn't have to 😌💅

🍓 ARGUMENTS 🍓

  • bus — the BUS 👑 the HD-audio bus object you're handing over. yes, that's literally all it says. the BUS. capital letters. iconic, honestly.
  • res — the unsolicited event itself, fr fr. specifically: the lower 32bit of RIRB entry 💖
  • res_ex — the codec addr and flags 🌈 which is the upper 32bit or RIRB entry (that's what the page says, and we're quoting it exactly, no cap).

💜 DESCRIPTION 💜

So what does she actually do? She adds the given event to the queue. That's it. That's the whole gig ✨ The events get processed in the workqueue asynchronously — so it's giving "drop it in the group chat and let the server handle it", not "stand there waiting for a reply" 🧚

🚨 The instruction that matters: call this function in the interrupt handler when RIRB receives an unsolicited event. in. the. interrupt. handler. don't get cute about it 😭💀
