megasas_setup_irqs_msix(9)

📦 version 7.3.1, in nixpkgs unstable

💅 megasas_setup_irqs_msix ✨

okay so bestie, welcome to section 9 of the Kernel API Manual — yes we're in kernel-land today, and no, it's not as scary as it sounds 🫶. This one's a function page: megasas_setup_irqs_msix. Say it three times fast, I dare you 😭.

🌸 NAME 🌸

megasas_setup_irqs_msix — registers MSI-x interrupts ✨ (that's the whole vibe, fr fr)

🎀 SYNOPSIS 🎀

int megasas_setup_irqs_msix (struct megasas_instance *instance , u8
is_probe );

it gives back an int, and it takes the two args below 👇 no cap.

🦋 ARGUMENTS 🦋

  • instance — the adapter soft state 💖 (the soft-state struct for this adapter, that's the whole thing)
  • is_probe — driver probe check 🔍 (literally just the "are we in probe?" flag)

🌈 DESCRIPTION 🌈

okay so here's the moment: do not enable the interrupt, only set up the ISRs. That's it. That's the job. Setup only, no enabling — the way that megasas_setup_irqs_msix keeps it strictly setup-flavored 💅.

it returns 0 on success ⭐ (zero means slay, we move).

lowkey important: setup ≠ enable. If you're expecting this to turn interrupts on, bestie, it does not, and it says so right there. 🙈

like, the whole megaraid friend group showed up 🫶 iconic behavior honestly.

okay and before I go — this page lives in ./drivers/scsi/megaraid, dated October 2026, and it's megasas_setup_irqs_msix(9) for life 💜🧚 bye bestie, go set up some ISRs (but do NOT enable them, I'm watching you 👀)
