ENUM GENI_SE_XFER_MODE(9)

💅 enum geni_se_xfer_mode(9) — from the Kernel API Manual, bestie 🫶

okay so picture this: it's giving "Kernel API Manual" energy, and the star of the show is enum geni_se_xfer_mode, which is literally just the list of transfer modes that Serial Engines support ✨. that's it. that's the whole vibe. no cap.

🎀 NAME 🎀

enum geni_se_xfer_mode — the transfer modes supported by Serial Engines, periodt 💅

🌸 SYNOPSIS 🌸

enum geni_se_xfer_mode {
    GENI_SE_INVALID ,
    GENI_SE_FIFO ,
    GENI_SE_DMA ,
    GENI_GPI_DMA

};

🦋 CONSTANTS 🦋

bestie, let me walk you through the cast 👑

• GENI_SE_INVALID — the invalid mode. it's giving "not it" 🙈 this one is literally just here to say nope, not valid.
• GENI_SE_FIFO — FIFO mode! data gets transferred with the SE FIFO by the programmed IO method. old school, but she works 💖
• GENI_SE_DMA — Serial Engine DMA mode. data is transferred with the SE by the DMAengine that's internal to the SE. self-sufficient queen 👑
• GENI_GPI_DMA — GPI DMA mode. data is transferred using a DMAengine configured by a firmware residing on a GSI engine. and here's the tea ☕: this DMA name is interchangeably used as GSI or GPI, and those seem to imply the same DMAengine. iykyk 🧚
