tso_dma_map_complete(9)

hiii bestie 💖 welcome to the Kernel API Manual page for tso_dma_map_complete(9). this one is literally about cleanup at completion time, and it’s giving “bye, mapping” energy ✨

🎀 NAME 🎀

tso_dma_map_complete — tear down mapping at completion time 💅✨

like, the function comes through when it’s time to tear down the mapping at completion time, no cap 🫶

✨ SYNOPSIS ✨

bool tso_dma_map_complete (struct device *dev , struct
       tso_dma_map_completion_state *cstate );

okay so that’s the exact signature, spacing and all 👀 bool is the return vibe, and the two arguments are right there 🎀

🫶 ARGUMENTS 🫶

• dev — the device that owns the mapping 👑 main-character device energy, fr fr
• cstate — state saved by tso_dma_map_completion_save 🎀 it’s the saved-state bestie from that other function, iykyk

💖 RETURN 💖

• true — the IOVA path was used and the mapping has been destroyed ✅ slay, cleanup is done
• false — the fallback per-region path was used, and the driver must unmap via its normal completion path 👀 so not the IOVA path, and the driver still has to do its normal unmapping thing
