tso_dma_map_completion_save(9)

💖 NAME 💖

okay bestie, welcome to the tso_dma_map_completion_save(9) page from the Kernel API Manual ✨ tso_dma_map_completion_save — save state needed for completion-time cleanup. That’s the whole assignment, no cap.

✨ SYNOPSIS ✨

void tso_dma_map_completion_save (const struct tso_dma_map *map , struct
       tso_dma_map_completion_state *cstate );

🎀 ARGUMENTS 🎀

• map — the xmit-time DMA map. Yes, the map from xmit time, literally.
• cstate — driver-owned storage that persists until completion. It’s the driver’s own little storage spot that sticks around until completion 💅.

🦋 DESCRIPTION 🦋

so here’s the flow: it should be called at xmit time to update the completion state and later passed to tso_dma_map_complete. That’s it — iconic, short, and very much a “do this at xmit, use it at completion” situation 🫶.
