fw_iso_conte..._completions(9)

✨ NAME ✨

okay so bestie, this is fw_iso_context_flush_completions(9) — it's the one from the Kernel API Manual — and what it does is process the isochronous context in the current process context. that's literally the whole vibe. 🎀

---

🌸 SYNOPSIS 🌸

int fw_iso_context_flush_completions (struct fw_iso_context *ctx );

---

🦋 ARGUMENTS 🦋

• ctx — the isochronous context. that's it, that's the one and only argument, she's the main character 💅

---

💖 DESCRIPTION 💖

so what actually happens here? you're processing the isochronous context in the current process context — like, right here, right now, in your own process, no delaying the slay. ✨

when a queued packet buffer with the interrupt flag is completed, the registered callback function gets called. and when does that happen? either after transmission in the IT context, or after being filled in the IR context — both paths, both iconic.

plus (not done yet bestie, there's more 🫶):

• the callback function is also called for the packet buffer completed at last
• and the callback function is called as well when the header buffer in the context becomes full

and if you're like "hmm, I need to process the context asynchronously instead" — no worries, fw_iso_context_schedule_flush_completions is available instead. she's right there for you 💜

---

🌈 CONTEXT 🌈

okay so important vibe check: this runs in process context. and yes — it may sleep due to disable_work_sync. so like, don't call it somewhere that sleeping is illegal, because she will nap on you 😭💀
