STRUCT SDMA_CHANNEL_CONTROL(9)

💅 struct sdma_channel_control(9) 💅

okay bestie, welcome to the Kernel API Manual — we're looking at struct sdma_channel_control, and it is literally the Channel control Block. no cap, that's the whole vibe. 🎀

✨ NAME ✨

struct sdma_channel_control — Channel control Block. periodt. 💅

🌸 SYNOPSIS 🌸

okay so here's the struct in all its glory, copied exactly:

       struct sdma_channel_control {
           u32 current_bd_ptr;
           u32 base_bd_ptr;
           u32 unused[2];
        };

🎀 Members 🎀

• current_bd_ptr — current buffer descriptor processed. that's it, that's the field. 💖
• base_bd_ptr — first element of buffer descriptor array. main character location energy. ✨
• unused — padding. The SDMA engine expects an array of 128 byte control blocks. don't touch it, it's doing padding things. 🫶

🔥 SEE ALSO 🔥

• Kernel file ./drivers/dma/imx-sdma.c — yes bestie, that's the file.
• struct sdma_state_registers(9)
• struct sdma_context_data(9)
• struct sdma_desc(9)
