STRUCT NFP_RTSYM(9)

💅 struct nfp_rtsym(9) 💅

okay bestie, so this is a page from the Kernel API Manual and it's literally just one struct, but she's kind of a big deal. This is the RTSYM descriptor — the little record that tells you everything about a symbol in the NFP firmware world. no cap, it's giving "tiny struct, huge responsibility." 🎀

✨ NAME ✨

struct nfp_rtsym — the RTSYM descriptor, aka the glow-up card for a symbol 🔥

---

🌈 SYNOPSIS 🌈

struct nfp_rtsym {
    const char *name;
    u64 addr;
    u64 size;
    enum nfp_rtsym_type type;
    int target;
    int domain;
 };

look at her. six fields. main character energy fr fr 🫶

🌸 Members 🌸

okay so let's do a vibe check on every single field, no skipping, we don't do that here 💖

• name — the symbol's name. yep, that's it, that's the whole field. iconic minimalism 💅
• addr — where the symbol lives, address-wise, inside the domain/target's address space. lowkey the whole point of the struct ngl 📍
• size — how big the symbol is, measured in bytes. don't forget the bytes part, bestie, units matter 😭
• type — the symbol's NFP_RTSYM_TYPE_*. the asterisk is doing a lot of work there, iykyk ⭐
• target — the CPP Target identifier, or one of the NFP_RTSYM_TARGET_* values. two ways to say the same thing, she's flexible like that 🦋
• domain — the CPP Target Domain (island). island!! like her own little isolated paradise 🏝️

bestie reminder: target and domain are different things — one's the target identifier, one's the domain/island. don't be out here swapping them, i'm begging 🙈

the kernel file you want is:

go read it, she's right there 💜
