megasas_alloc_irq_vectors(9)

💖 megasas_alloc_irq_vectors 💖

okay so welcome to the Kernel API Manual, bestie — this one's about megasas_alloc_irq_vectors, and yes it's a kernel function, and yes we're gonna get through it together 🫶

---

✨ NAME ✨

megasas_alloc_irq_vectors — Allocate IRQ vectors/enable MSI-x vectors 🎀

like, that's the whole job description and it ate, no notes.

---

✨ SYNOPSIS ✨

void megasas_alloc_irq_vectors (struct megasas_instance *instance );

it's giving very short, very void, very "i return nothing and i know it" 💅

---

✨ ARGUMENTS ✨

• instance — Adapter soft state. that's it, that's the whole argument. one (1) pointer, one (1) struct, zero (0) drama 🌸

---

✨ RETURN ✨

void — literally returns nothing, it's giving "i did the thing, don't ask me for a receipt" 😭

---

✨ SEE ALSO ✨

first up, the source file if you wanna read it with your own eyeballs 👀:

Kernel file ./drivers/scsi/megaraid/megaraid_sas_base.c

and now the full squad — every single one, no skips, no cuts, we do not leave a friend behind 💜

ngl there's no DESCRIPTION section on this page and i'm not about to make one up — the facts are the facts, periodt 💅

and that's the page!! 🦋 this legend lives under ./drivers/scsi/megaraid, it's dated October 2026, and its name is — say it with me — megasas_alloc_irq_vectors(9) 👑✨ bye bestie, go alloc some IRQ vectors, slay 🎀
