STRUCT SOF_IPC4_DMA_CONFIG_TLV(9)

💅 NAME 💅

okay so bestie, meet struct sof_ipc4_dma_config_tlv — literally just the DMA configuration wrapper, no cap ✨

it's a Kernel API Manual situation, and this little icon is the main character 🎀

---

✨ SYNOPSIS ✨

here's the whole vibe, character for character, don't touch a thing 🫶

struct sof_ipc4_dma_config_tlv {
    uint32_t type;
    uint32_t length;
    struct sof_ipc4_dma_config dma_config;
 };

---

🌸 Members 🌸

so there's three of them and they each have a job 💅

• type — set it to SOF_IPC4_GTW_DMA_CONFIG_ID. that's the assignment, that's the whole task, periodt 🎯
• length — this one's a lil math situation: it equals sizeof(struct sof_ipc4_dma_config) + dma_config.dma_priv_config_size. yes it's giving arithmetic, but it's giving correct arithmetic 💖
• dma_config — the actual DMA configuration itself, the real one, the one doing the work 🔥
