STRUCT FSL_MC_OBJ_DESC(9)

💖 struct fsl_mc_obj_desc(9) 💖

okay bestie, so this is a page from the Kernel API Manual and it's literally all about struct fsl_mc_obj_desc — the Object descriptor. That's it, that's the whole vibe. 🦋 It's the little info-card every object in the fsl-mc world carries around so the kernel knows who's who. iykyk.

✨ NAME ✨

struct fsl_mc_obj_desc — Object descriptor 👑

---

🌸 SYNOPSIS 🌸

here's the whole struct, copied exactly because we do NOT mess with code, bestie:

struct fsl_mc_obj_desc {
    char type[16];
    int id;
    u16 vendor;
    u16 ver_major;
    u16 ver_minor;
    u8 irq_count;
    u8 region_count;
    u32 state;
    char label[16];
    u16 flags;
 };

🎀 Members 🎀

like a group chat roster but for struct fields, let's go 🫶

• type — the Type of object, and it's a NULL terminated string. so no funny business with the termination, pls. 😌
• id — the ID</> of the logical object resource. its little name tag fr fr. 🏷️
• vendor — the Object vendor identifier. who made it, basically. 💅
• ver_major — the Major version number. the big number energy. 🎀
• ver_minor — the Minor version number. the lil sequel number. ✨
• irq_count — the Number of interrupts supported by the object. count 'em. 🔥
• region_count — the Number of mappable regions supported by the object. mappable, iconic, we love her. 🌈
• state — the Object state, which is a combination of FSL_MC_OBJ_STATE_ states. (yes, a combination — it's a bitmask moment, not a one-and-done.) ⭐
• label — the Object label: a NULL terminated string again. two NULL-terminated strings in one struct, she's high maintenance and we respect it. 💜
• flags — the Object's flags. mysterious. vague. main character energy. 🙈
