msgdma_tx_submit(9)

💖 NAME 💖

okay so bestie, this is msgdma_tx_submit(9) from the Kernel API Manual, and its whole job is literally to submit a DMA transaction. That’s the vibe, no cap. ✨

🎀 SYNOPSIS 🎀

dma_cookie_t msgdma_tx_submit (struct dma_async_tx_descriptor *tx );

🌸 ARGUMENTS 🌸

• tx — async transaction descriptor pointer. That’s the one argument, bestie, and she is exactly what she says on the label. 🫶

🦋 RETURN 🦋

she returns a cookie value 🍪 — yes, the dma_cookie_t kind, not the edible kind, sadly.
