STRUCT STEDMA40_HALF_CHANNEL_INFO(9)

🎀 struct stedma40_half_channel_info(9) 🎀

okay bestie, welcome to the Kernel API Manual — we're decoding this little struct together, no cap. It's giving dst/src channel configuration, and honestly it's a short one, so let's slay every field. 💖

✨ NAME ✨

struct stedma40_half_channel_info — dst/src channel configuration. That's the whole vibe: it's the dst/src channel configuration struct, periodt. 💅

🦋 SYNOPSIS 🦋

struct stedma40_half_channel_info {
    bool big_endian;
    enum dma_slave_buswidth data_width;
    int psize;
    enum stedma40_flow_ctrl flow_ctrl;
 };

🌸 Members 🌸

• big_endian — true if the src/dst should be read as big endian. It's a bool, bestie, so it's literally true-or-false energy. ✨
• data_width — the data width of the src/dst hardware. In the struct it's typed as enum dma_slave_buswidth. Iconic. 🎀
• psize — it's right there in the struct as an int psize, and this page doesn't hand us a separate description for it, so we're not making one up. No invented lore, fr fr. 💀
• flow_ctrl — flow control on/off. In the struct it's typed as enum stedma40_flow_ctrl. Slay. 🔥
