💅 vcn_v4_0_3_set_irq_funcs(9) — the Kernel API Manual, bestie edition 🎀

okay so you opened up the Kernel API Manual (that's the manual name, bestie, write it down) and you landed on this page: vcn_v4_0_3_set_irq_funcs. Yes, that's a whole lot of underscores. Yes, it's iconic. Let's get into it ✨

🌸 NAME 🌸

vcn_v4_0_3_set_irq_funcs — literally just sets the VCN block interrupt's irq functions. That's the whole vibe check. It sets irq functions, for the VCN block, for interrupts. Periodt 💅

✨ SYNOPSIS ✨

void vcn_v4_0_3_set_irq_funcs (struct amdgpu_device *adev );

That's it. That's the whole call. One function, one argument, no drama 🫶

🎀 ARGUMENTS 🎀

  • adev — an amdgpu_device pointer. That's your handle on the whole AMD GPU device, and it's what gets passed into this function. She's the main character here 👑

🦋 DESCRIPTION 🦋

Okay so what does this actually do? Per the manual: set VCN block interrupt irq functions. That's the entire description and honestly we're respecting it for that. It's giving "short and sweet, knows exactly what she is" energy 🌈

So, no cap, the function's whole job is wiring up the interrupt irq functions for the VCN block. No extra lore in this page, bestie — what you see is what you get, and what you get is irq functions being set 🔥

Not me telling you to just be normal about this — the manpage literally gives you one sentence. I'm not gonna invent backstory that isn't in the source, that would be a fake rumor and we don't do that here 🙈
