STRUCT TSO_DMA_MAP_COMPLETION_STATE(9)

💖 NAME 💖

Okay bestie, welcome to the struct tso_dma_map_completion_state(9) page from the Kernel API Manual — the header gets cutely truncated to struct tso_...letion_state(9), iykyk. This struct is literally the completion-time cleanup state. 💅

✨ SYNOPSIS ✨

       struct tso_dma_map_completion_state {
           struct dma_iova_state iova_state;
           size_t total_len;
        };

🫶 Members 🫶

• iova_state — DMA IOVA state (when IOMMU available) ✨
• total_len — total payload length of the IOVA mapping 🌸

🦋 Description 🦋

Drivers store this on their SW ring at xmit time via tso_dma_map_completion_save, then call tso_dma_map_complete at completion time. That's the whole flow, bestie — save at xmit, complete at completion. 💜
