gsi_trans_tx_completed(9)

💖 gsi_trans_tx_completed — from the Kernel API Manual, bestie 💖

Okay so picture this: you're deep in the Kernel API Manual (yes, that one) and you land on this little function. Don't panic — she's actually super chill, and I'm gonna walk you through her like we're gossiping at lunch. 🎀

✨ NAME ✨

gsi_trans_tx_completed — the girl whose whole job is literally just reporting completed TX transactions. That's it, that's the vibe. 👑

---

🦋 SYNOPSIS 🦋

void gsi_trans_tx_completed (struct gsi_trans *trans );

Nothing returned, nothing fancy — she just does the thing and dips. 💅

---

🌸 ARGUMENTS 🌸

• trans — the TX channel transaction that has completed, aka the one who just finished her shift and is clocking out 🫶

---

🔥 DESCRIPTION 🔥

So here's the tea: this function reports that a transaction on a TX channel has completed. Simple? Yes. But the way it actually works is kind of iconic, so let me break it down.

At the moment a transaction is committed, we record in the transaction — like, physically inside the struct, bestie — its channel's committed transaction count and byte count. Snapshot taken, memory saved. 📸

Transactions are then completed in order (no cutting the line, periodt), and the difference between the channel's byte/transaction count when the transaction was committed and the count when it completes tells us exactly how much data has been transferred while that transaction was pending. Math! Slay! ✨

Then we report all of this up to the network stack, which uses it to manage the rate at which data gets sent to hardware. So she's basically the messenger keeping the whole flow smooth. Not me being obsessed with a rate-limiting pipeline 😭

Aaaand that's the whole page, bestie — no cap. ✨ Signing off with all the love from ./drivers/net/ipa, version October 2026, still serving that gsi_trans_tx_completed(9) main character energy. 🧚‍♀️💖 mwah!
