STRUCT STM32_DMA_MDMA_CONFIG(9)

okay bestie, welcome to the struct stm32..._mdma_config(9) page from the Kernel API Manual 💖 this one is short, but it’s lowkey iconic: a tiny struct with big STM32 DMA MDMA energy.

🌸 NAME 🌸

struct stm32_dma_mdma_config — STM32 DMA MDMA configuration. That’s the name, periodt. It’s the struct for this exact configuration situation, no cap ✨.

✨ SYNOPSIS ✨

Here’s the exact struct shape, character-for-character:

struct stm32_dma_mdma_config {
    u32 stream_id;
    u32 ifcr;
    u32 tcf;
 };

Three members, all u32: stream_id, ifcr, and tcf. The closing brace has that one-space indentation era, and yes, we’re keeping it exactly as shown 🫶.

🎀 Members 🎀

Okay so, member-by-member vibe check:

• stream_id — DMA request to trigger STM32 MDMA transfer. That’s the DMA request that triggers the STM32 MDMA transfer, literally 💅.
• ifcr — DMA interrupt flag clear register address, used by STM32 MDMA to clear the DMA Transfer Complete flag. So it’s the address STM32 MDMA uses to clear that flag, iykyk.
• tcf — DMA Transfer Complete flag. That’s the flag itself, bestie. Transfer Complete energy 🦋.

💅 SEE ALSO 💅

Footer sign-off 🎀: source ./drivers/dma/stm32, date October 2026, and running title struct stm32..._mdma_config(9) — that’s the source/version-and-date moment, and it ate. Bye bestie, go handle your STM32 DMA MDMA config with main character energy 💖✨
