iavf_alloc_queues(9)

📦 version 7.3.1, in nixpkgs unstable

🦋 iavf_alloc_queues — bestie, it's ring-allocating time 🎀

okay so real talk: this one's from the Kernel API Manual, section 9 (that's the kernel-internals girlies, iykyk 💅). It's a little function that goes and gets memory for all the rings. Short page, but it ATE. Let's get into it ✨

✨ NAME ✨

iavf_alloc_queues — literally just: allocate memory for all rings 🫶 no cap, that's the whole job.

🌸 SYNOPSIS 🌸

int iavf_alloc_queues (struct iavf_adapter *adapter );

bestie it returns an int, and it takes exactly one (1) argument. iconic minimalism 💖

🎀 ARGUMENTS 🎀

  • adapter — the board private structure you're initializing. yes queen, hand over your adapter and let her cook 🍓

⭐ DESCRIPTION ⭐

So here's the vibe: we allocate one ring per queue at run-time, because — plot twist — we literally don't know the number of queues at compile-time 😭 the kernel doesn't tell us until later, so we gotta be flexible. main character energy fr fr.

And the polling_netdev array? highkey it's intended for Multiqueue, but ngl it should work fine with just a single queue too. she's versatile like that 🧚💜

💜 SEE ALSO 💜

the whole extended universe, bestie — every one of these is a real one 🔥

💀 friendly reminder bestie: that list is LONG, but every single one is a real cross-reference, so don't come for me about it, I didn't invent them, I just gave them a ✨moment✨
