virtqueue_set_affinity(9)

🌸 NAME 🌸

Okay so welcome to virtqueue_set_affinity(9) — straight outta the Kernel API Manual, bestie. This one is all about setting affinity for a virtqueue. Very demure, very kernel-coded. 💅

✨ SYNOPSIS ✨

int virtqueue_set_affinity (struct virtqueue *vq , const struct cpumask
*cpu_mask );

🎀 ARGUMENTS 🎀

• vq — the virtqueue. The main character of this function, lowkey.
• cpu_mask — the cpu mask. The vibe map for where things should go. 🦋

💖 DESCRIPTION 💖

Real talk: this function is best-effort. Like, it tries to set the affinity hint, but it may not actually get set — and that's not a skill issue, it's because of config support, irq type, and sharing. So yeah, it's giving "I'll do my best" energy, not "guaranteed slay" energy. 😭

Important caveat, bestie: the affinity hint may not be set. Do not come for this function if the hint doesn't stick — it literally warned you. 🙈
