📦 version 7.3.1, in nixpkgs unstable

👑 ixgbevf_set_num_queues — the kernel API manual page, bestie edition ✨

okay so this is ixgbevf_set_num_queues(9) from the Kernel API Manual, and it's literally the queue-allocating main character of the ixgbevf driver. sit down, grab a lil snack 🍓, we're getting into it.

✨ NAME ✨

ixgbevf_set_num_queues — allocate queues for the device, feature dependent 💅

🦋 SYNOPSIS 🦋

void ixgbevf_set_num_queues (struct ixgbevf_adapter *adapter );

like, that's the whole signature. no return value, no cap. 🫶

🎀 ARGUMENTS 🎀

  • adapter — the board private structure you're initializing. that's the lil homegirl you're setting up 💖

🌸 DESCRIPTION 🌸

okay so this is the top level queue allocation routine, no big deal. but listen — the order here is very important, and i mean very. you start with the "most" number of features turned on at once, and you end with the smallest set of features.

the way that works is genuinely iconic: this way, large combinations can be allocated if they're turned on, and the smaller combinations are the fall through conditions. periodt. 🔥

ngl bestie, do not shuffle the order of this. the ordering is load-bearing. 🙈

⭐ SEE ALSO ⭐

the kernel file lives at:

and here's the whole extended friend group, all of them, in order, exactly as-is 💜:

🌈 the sign-off 🌈

this lil page says it's from ./drivers/net/ethernet/intel/i... (yes, the footer literally truncates it like that, she's mysterious 💀) and it's dated October 2026, and the title is ixgbevf_set_num_queues(9) all over again. so cute. anyway go forth and allocate your queues in the right order bestie, iykyk 🧚💖✨
