STRUCT DPAA2_IO_NOTIFICATION_CTX(9)

💖 struct dpaa2_io_notification_ctx(9) 💖

okay bestie, welcome to the Kernel API Manual, this is the page for struct dpaa2_io_notification_ctx and it's literally the DPIO notification context structure. she's a struct, she's got lore, let's get into it 🫶

---

✨ NAME ✨

struct dpaa2_io_notification_ctx — the DPIO notification context structure. that's her. that's the whole vibe. 🎀

---

🌸 SYNOPSIS 🌸

struct dpaa2_io_notification_ctx {
    void (*cb)(struct dpaa2_io_notification_ctx *ctx);
    int is_cdan;
    u32 id;
    int desired_cpu;
    int dpio_id;
    u64 qman64;
    struct list_head node;
    void *dpio_private;
 };

no cap, that's the whole thing. every field, exactly as it lives. let's do a member-by-member vibe check 👑

💅 Members 💅

• cb — the callback that gets invoked when the notification arrives. like, when the notification pulls up, this is the function that answers the door. 🔥
• is_cdan — zero for FQDAN, non-zero for CDAN. that's the whole flag, she's simple like that.
• id — the FQID or channel ID, and you literally need it for rearm. don't lose it bestie 😭
• desired_cpu — the cpu on which the notifications will show up. and if you don't care? use DPAA2_IO_ANY_CPU. main character energy, zero preferences.
• dpio_id — the dpio index.
• qman64 — the 64-bit context value that shows up in the FQDAN/CDAN. yep, it's giving "i'm just here to be a value" and honestly same.
• node — the list node. tiny, does its job, iconic. 🦋
• dpio_private — the dpio object internal to dpio_service.

🧚 Description 🧚

this whole struct is used when a FQDAN/CDAN registration is made by drivers. that's it, that's the tea. it's the context that comes along with the registration, periodt. 💜

okay that's the page, bestie! this one lives in ./include/soc/fsl, it's dated October 2026, and yes it's the same struct dpaa2...fication_ctx from the Kernel API Manual up top — the header and footer already told you, but i'm telling you again because you're my favorite 🥰💖 slay, go register those notifications responsibly 🎀🌈
