STRUCT DPDMAI_ATTR(9)

💅 struct dpdmai_attr(9) 💅

okay bestie, so this is a page from the Kernel API Manual and honestly? it's a little cutie. it's the struct that holds all the DPDMAI attributes — like, the whole personality of a DPDMAI object in one tidy little bundle. let's get into it 🎀

---

✨ SYNOPSIS ✨

here's the whole vibe, verbatim, no cap:

struct dpdmai_attr {
    int id;
    struct {
      u16 major;
      u16 minor;
    } version;
    u8 num_of_priorities;
    u8 num_of_queues;
 };

look at her. nested struct and everything. main character energy fr 💜

🌸 Members 🌸

okay so every field, one by one, no skipping (i would never):

• id — the DPDMAI object ID. it's giving "who am I" but make it kernel. 🪪
• version — the DPDMAI version. the whole version moment.
• version.major — the DPDMAI major version. the big number. the headliner. 👑
• version.minor — the DPDMAI minor version. the little number riding shotgun. 🦋
• num_of_priorities — number of priorities. how many priority levels we're working with, bestie.
• num_of_queues — number of the DMA queues. that's the queue count, periodt. 🧚

lowkey important: version is a nested anonymous-ish struct with exactly two u16 fields, major and minor. that's the shape, don't come for me. 💅

if you're obsessed with this one (and why wouldn't you be), go read her friends over in the Kernel file ./drivers/dma/fsl-dpaa2-qdma/dpdmai.h:

• struct dpdmai_cfg(9)
• enum dpdmai_dest(9)
• struct dpdmai_dest_cfg(9)
• struct dpdmai_rx_queue_cfg(9)
• struct dpdmai_rx_queue_attr(9)

a whole friend group. iykyk 🌈

aaaaand that's the page!! mwah 💖 this lil drop came from ./drivers/dma/fsl-dpaa2-qdma and it's dated October 2026 — so yeah, technically from the future, which is iconic of her honestly. go forth and slay your DPDMAI attributes, bestie 🫶✨
