irq_calc_affinity_vectors(9)

💖 NAME 💖

okay bestie, welcome to the Kernel API Manual — this page is all about irq_calc_affinity_vectors, and its whole personality is Calculate the optimal number of vectors ✨. That's the name, that's the job, no cap.

✨ SYNOPSIS ✨

here's the signature, and yes you copy it exactly, character for character:

unsigned int irq_calc_affinity_vectors (unsigned int minvec , unsigned
       int maxvec , const struct irq_affinity *affd );

🎀 ARGUMENTS 🎀

• minvec — the minimum number of vectors available 🫶. it's the lower bound, the "at least this many" bestie.
• maxvec — the maximum number of vectors available 🔥. it's the upper bound, the "no more than this" moment.
• affd — description of the affinity requirements 👑. it's literally the struct that says what the affinity needs are.

🦋 SEE ALSO 🦋

• Kernel file ./kernel/irq/affinity.c — the source file for your reading pleasure 💅
• irq_create_affinity_masks(9) — another manual page, go get that lore 🌸
