i40e_alloc_vsi_res(9)

💖 i40e_alloc_vsi_res(9) — Kernel API Manual, bestie edition 🎀

okay so like. this is a page from the Kernel API Manual, and the function is i40e_alloc_vsi_res — the way it lives in the Intel i40e driver and does exactly one (1) job but says it in the most mysterious way possible. icon behavior tbh. ✨

---

🌸 NAME 🌸

i40e_alloc_vsi_res — and that's it. no description. the NAME section literally just trails off into the void 💀 which honestly? main character energy. it doesn't owe you an explanation.

---

🦋 SYNOPSIS 🦋

here's the whole signature, copied exactly, no cap:

int i40e_alloc_vsi_res (struct i40e_vf *vf , u8 idx );

that's her. that's the function. returns an int, takes two things. go off 👑

---

👑 ARGUMENTS 👑

two args, both eating:

• vf — pointer to the VF info 🫶 like, this is the VF's whole little info blob, and we're passing a pointer to it. give it what it needs.
• idx — the VSI index. and listen, this one's conditional baby: it applies only for ADq mode, and it's zero otherwise. so if you're not in ADq mode, bestie, it's 0. don't get cute with it 🙈

---

⭐ DESCRIPTION ⭐

alloc VF vsi context & resources

that's the entire description. allocates the VF VSI context and its resources. short, sweet, to the point, zero notes, absolutely ate and left no crumbs 💅

okay buckle up buttercup because this list is LONG and gorgeous and I'm not skipping a single one of them — every reference, in order, untouched:

and yes I read every single one of those. reading comprehension slay 🌈

🫶 quick note bestie: the NAME description is genuinely blank in the source, and the DESCRIPTION is genuinely just that one line. I'm not hiding lore from you — that's all there is. iykyk.

sign-off time ✨ this page comes from ./drivers/net/ethernet/intel/i40e, dated October 2026, and the manual page header/footer both say i40e_alloc_vsi_res(9) — now go forth and allocate those VSI contexts and resources, you absolute legend 💖🦋🍓
