STRUCT DPDMAI_CFG(9)

✨ NAME ✨

struct dpdmai_cfg — Structure representing DPDMAI configuration. That's the whole name vibe, and she's iconic for it 💅

🌸 SYNOPSIS 🌸

okay so here's the exact shape, bestie, no cap:

       struct dpdmai_cfg {
           u8 num_queues;
           u8 priorities[DPDMAI_PRIO_NUM];
        };

💅 Members 💅

• num_queues — literally the number of the DMA queues. That's it, that's the whole assignment: Number of the DMA queues.
• priorities — priorities for the DMA hardware processing, periodt. Valid priorities are configured with values 1-8, and the entry following the last valid entry should be configured with 0. Don't forget that zero, okay? It's giving "please configure this correctly" energy 🫶

bestie, the original really does say the entry following the last valid entry should be configured with 0 — so keep that in mind 💖
