STRUCT SOF_IPC4_DMA_DEVICE_STREAM_CH_MAP(9)

okay bestie, welcome to struct sof_ipc4_dma_device_stream_ch_map(9) — yes, the whole name — from the Kernel API Manual 💅✨

💖 NAME 💖

struct sof_ipc4_dma_device_stream_ch_map is the abstract representation of channel mapping to DMAs. It's giving tiny-but-iconic struct energy 🎀

✨ SYNOPSIS ✨

struct sof_ipc4_dma_device_stream_ch_map {
    uint32_t device;
    uint32_t channel_mask;
 };

🫶 Members 🫶

• device — representation of hardware device address or FIFO 📍
• channel_mask — channels handled by device. Channels are expected to be contiguous ⭐
