ENUM DMA_TRANSACTION_TYPE(9)

🌸 NAME 🌸

enum dma_transaction_type — DMA transaction types/indexes. Okay bestie, you're reading enum dma_transaction_type(9) from the Kernel API Manual, and the name is literally right there: DMA transaction types/indexes. That's the whole vibe. 💅

✨ SYNOPSIS ✨

Here's the entire enum, same order, same constants, same commas — no editing, periodt:

enum dma_transaction_type {
    DMA_MEMCPY ,
    DMA_XOR ,
    DMA_PQ ,
    DMA_XOR_VAL ,
    DMA_PQ_VAL ,
    DMA_MEMSET ,
    DMA_MEMSET_SG ,
    DMA_INTERRUPT ,
    DMA_PRIVATE ,
    DMA_ASYNC_TX ,
    DMA_SLAVE ,
    DMA_CYCLIC ,
    DMA_INTERLEAVE ,
    DMA_COMPLETION_NO_ORDER ,
    DMA_REPEAT ,
    DMA_LOAD_EOT ,
    DMA_TX_TYPE_END

};

🧩 Constants 🧩

The way this page is serving -- undescribed -- for every single constant is lowkey giving placeholder energy, but here they all are anyway, bestie — nothing skipped, fr fr:

• DMA_MEMCPY — -- undescribed --
• DMA_XOR — -- undescribed --
• DMA_PQ — -- undescribed --
• DMA_XOR_VAL — -- undescribed --
• DMA_PQ_VAL — -- undescribed --
• DMA_MEMSET — -- undescribed --
• DMA_MEMSET_SG — -- undescribed --
• DMA_INTERRUPT — -- undescribed --
• DMA_PRIVATE — -- undescribed --
• DMA_ASYNC_TX — -- undescribed --

🚨 Note 🚨

Bestie warning, no cap: the DMA_ASYNC_TX capability is not to be set by drivers. It is automatically set as dma devices are registered. So don't touch it, okay? 😭
