ipa_interrup...spend_enable(9)

💅 ipa_interrupt_suspend_enable(9) — from the Kernel API Manual, bestie

Okay so we're diving into the kernel API manual today, and this one is a tiny little function with a big job. Strap in. 🎀

---

✨ NAME ✨

ipa_interrupt_suspend_enable — literally just enables TX_SUSPEND for an endpoint. That's the whole gig. Slay.

---

🦋 SYNOPSIS 🦋

void ipa_interrupt_suspend_enable (struct ipa_interrupt *interrupt , u32
       endpoint_id );

Yeah, it returns void — no return value, no drama, she just does the thing and leaves. 👑

---

🌸 ARGUMENTS 🌸

• interrupt — the IPA interrupt structure. Like, the whole vibe container for the interrupt stuff. Pass her in.
• endpoint_id — the endpoint whose interrupt should be enabled. Tell her which one, she's not a mind reader. 💅

---

💀 NOTE 💀

Okay this part is lowkey important so pay attention bestie 🫶 — the "TX" in the name is from the perspective of the IPA hardware. Not yours. Not the AP's. The hardware's.

So a TX_SUSPEND interrupt arrives on an AP RX endpoint when packet data can't be delivered to the endpoint because it is suspended (or its underlying channel is stopped). That's it, that's the whole reason. It's giving "the packet tried her best but the endpoint was on do-not-disturb." 😭

That's the whole page, no cap. Stay iconic, go enable some interrupts, and remember — the hardware's TX is your RX. 🦋💜⭐
