ipa_endpoint_suspend_aggr(9)

🦋 ipa_endpoint_suspend_aggr — the Kernel API Manual page, bestie edition 💅

okay so you've stumbled into the <pink>ipa_endpoint_suspend_aggr</pink> page of the Kernel API Manual (section 9, kernel-space crew ✨). Sit down, grab a strawberry drink 🍓, and let's get into it.

🌸 NAME 🌸

ipa_endpoint_suspend_aggr — literally just emulate suspend interrupt. That's the whole vibe. It pretends a suspend interrupt happened. Iconic behaviour, no cap 💅

---

⭐ SYNOPSIS ⭐

void ipa_endpoint_suspend_aggr(struct ipa_endpoint *endpoint);

Returns void, so like… nothing comes back. She gives, she doesn't take 🫶

---

🎀 ARGUMENTS 🎀

• endpoint — the Endpoint on which we're emulating a suspend. That's the main character of this function, fr fr.

---

💖 DESCRIPTION 💖

So here's the tea ☕: this function emulates the suspend IPA interrupt so that it can unsuspend an endpoint that got suspended while it was holding an open aggregation frame. Basically rescuing an endpoint that got stuck mid-frame 😭🫶

And why do we need this dramatic workaround? Because of a hardware issue in IPA version 3.5.1 💀 — on that version the suspend interrupt just… doesn't get generated when it should. Rude. So we fake it ourselves. Not me fixing hardware bugs with software, but here we are ✨

ngl this whole function is a workaround, so just know that going in 🙈
