geni_se_tx_init_dma(9) 💅

okay bestie, welcome to the Kernel API Manual corner of the group chat. Today’s main character is geni_se_tx_init_dma(9) — yes, the (9) is giving kernel API manual energy, and we are seated. Let’s get into it. ✨

💖 NAME 💖

geni_se_tx_init_dma — Initiate TX DMA transfer on the serial engine. That’s the name, that’s the assignment, and it ate. 🫶

✨ SYNOPSIS ✨

void geni_se_tx_init_dma (struct geni_se *se , dma_addr_t iova , size_t len );

The return type is void, and there are three arguments in the mix. Short synopsis, big main character energy. 💅

🎀 ARGUMENTS 🎀

• se — pointer to the concerned serial engine. That’s the serial engine in question, bestie.
• iova — mapped DMA address. Literally the mapped DMA address.
• len — length of the TX buffer. The TX buffer’s length, periodt.

🦋 DESCRIPTION 🦋

okay so this function is used to initiate DMA TX transfer. That’s the whole description — no extra lore, no side quests, no unnecessary yapping. It literally initiates the DMA TX transfer, and honestly? Obsessed with the efficiency. 💅🔥
