🧊 ice_alloc_fd_res — bestie's guide to grabbing an FD resource for a VSI 💅

okay so this is from the ice Kernel API Manual, section 9, and it's literally the whole entire vibe of "hey kernel, can my VSI have an FD resource please." Sit down, grab a strawberry drink 🍓, we're getting into it.

✨ NAME ✨

ice_alloc_fd_res — allocate FD resource for a VSI 🫶

✨ SYNOPSIS ✨

int ice_alloc_fd_res (struct ice_vsi *vsi );

that's it. that's the whole call. one arg, one int back. no cap. 🌈

✨ ARGUMENTS ✨

  • vsi — pointer to the ice_vsi. like, the VSI. the one you're doing this for. she's the main character here 👑

✨ DESCRIPTION ✨

So this allocates the FD resources 💖 yep, that's the whole thing, she's a small function with a big job.

And because you're gonna ask "what does it return" — she returns 0 on success, -EPERM on no-op, or -EIO on failure. Note the middle one, bestie: -EPERM doesn't mean "you were bad," it means no-op, i.e. nothing happened. Don't panic, don't cry, just vibe check your logic 😭

lowkey memorize those three return values, because guessing is not it — 0 = slay, -EPERM = no-op, -EIO = it's giving failure 💀

✨ SEE ALSO ✨

kay so the kernel file this lives in is ./drivers/net/ethernet/intel/ice/ice_lib.c — screenshot that 📸 — and then there's a whole friend group of related functions, and I'm not skipping a single one of them because that would be rude to the whole group chat 💜

like, that's the entire friend group, every single one tagged 🎀

and that's the tea ☕ this page ships out of ./drivers/net/ethernet/intel/ice with a date stamp of October 2026 — so yeah, she's a lil time traveler, and honestly? iconic. bye bestie, go allocate responsibly 🦋💖
