💖 ice_vsi_alloc_q_vectors(9) 💖

okay bestie, welcome to the Kernel API Manual page for ice_vsi_alloc_q_vectors(9) — yes, the title is right there, we're doing this. ✨

🌸 NAME 🌸

ice_vsi_alloc_q_vectors — allocate memory for interrupt vectors 💅

🦋 SYNOPSIS 🦋

int ice_vsi_alloc_q_vectors (struct ice_vsi *vsi );

🎀 ARGUMENTS 🎀

• vsi — the VSI being configured. that's the whole mood 🫶

✨ DESCRIPTION ✨

Okay so here's the tea: we allocate one q_vector per queue interrupt. That's it, that's the job. If that allocation fails, we return -ENOMEM. No cap. 😭
