💅 xgene_dma_run_tx_complete_actions(9) 💅

okay so bestie, we're in the Kernel API Manual today and this one is literally the little cleanup gremlin of the X-Gene DMA world. no cap, it's a whole mood. ✨

🌸 NAME 🌸

xgene_dma_run_tx_complete_actions — cleanup a single link descriptor 🧹

---

✨ SYNOPSIS ✨

void xgene_dma_run_tx_complete_actions (struct xgene_dma_chan *chan ,
struct xgene_dma_desc_sw *desc );

like yes, that's the whole signature, she's short and she knows it 💅

---

🎀 ARGUMENTS 🎀

• chan — the X-Gene DMA channel, aka where all the drama happens 🦋
• desc — the descriptor to cleanup and free, we're putting her to rest 🪦✨

---

👑 DESCRIPTION 👑

so here's the tea: this function is used on a descriptor which has been executed by the DMA controller. like, the work is DONE, the controller already ate and left no crumbs 🔥

and then? it will run any callbacks, submit any dependencies. that's it, that's the whole job. iconic behaviour honestly 🫶
