ice_vsi_free_irq(9)

💅 ice_vsi_free_irq(9) — the "we're SO done with you, interrupt" era ✨

okay besties, gather 'round the kernel group chat because we're talking about ice_vsi_free_irq — it's a function in the kernel API manual and honestly? it does exactly one iconic thing: it frees the IRQ association with the OS. that's it, that's the whole vibe. she's a one-job queen and she ate. 👑

---

✨ SYNOPSIS ✨

void ice_vsi_free_irq (struct ice_vsi *vsi );

no cap, that's the whole signature. void return, so she doesn't even hand you back a little treat. she just does the thing and dips. 💨

---

🫶 ARGUMENTS 🫶

• vsi — this is the VSI being configured. it's a pointer to a struct ice_vsi, and it's literally the main character here. the whole function is about her interrupts. give her the attention she deserves. 🎀

🔥 SEE ALSO 🔥

okay so this is the part where literally everyone shows up to the party. the kernel file lives at ./drivers/net/ethernet/intel/ice/ice_lib.c — that's the address, bestie, write it down. 📍

heads up bestie: this is the kernel API manual, so we keep the references exactly as written — no paraphrasing, no "you know that one function." the kernel does not do vibes-based naming. 🙈

🦋 a lil sign-off 🦋

okay that's the page!! this gem comes to you from ./drivers/net/ethernet/intel/ice and the date on it is October 2026 — yes, the future is now, and the ice driver is thriving. stay free, stay iconic, and remember: free your IRQs and your IRQs will free you. periodt. 💜✨
