STRUCT ANNOTATED_DATA_STAT(9)

💅 struct annotated_data_stat(9)

okay so bestie, welcome to the Kernel API Manual — this one's about struct annotated_data_stat, which is literally just a big ol' pile of Debug statistics. That's the whole vibe. It counts stuff. It tells you why the annotate-data machinery gave up on a thing. Iconic, honestly. 🎀

✨ SYNOPSIS ✨

struct annotated_data_stat {
    int total;
    int no_sym;
    int no_insn;
    int no_insn_ops;
    int no_mem_ops;
    int no_reg;
    int no_dbginfo;
    int no_cuinfo;
    int no_var;
    int no_typeinfo;
    int invalid_size;
    int bad_offset;
    int insn_track;
 };

no cap, that's the whole struct. every field is an int. we love a consistent queen. 👑

🌸 Members 🌸

okay so here's the rundown of every single counter, and what sad little situation it's keeping track of:

• total — the Total number of entry. the big one. the main character. everything else is a subset of this. 💅
• no_sym — No symbol or map found. couldn't find it, moving on. 😭
• no_insn — Failed to get disasm line. the disassembly said "nope". 💀
• no_insn_ops — The instruction has no operands. like, at all. empty. nada.
• no_mem_ops — The instruction has no memory operands. close, but no memory access to look at.
• no_reg — Failed to extract a register from the operand. the register was simply not giving. 🙈
• no_dbginfo — The binary has no debug information. stripped binary behaviour fr fr.
• no_cuinfo — Failed to find a compile_unit. the cu info said "never heard of her". 🦋
• no_var — Failed to find a matching variable. no var, no match, no joy.
• no_typeinfo — Failed to get a type info for the variable. we know of her but not what she is.
• invalid_size — Failed to get a size info of the type. the size info is not size-ing.
• bad_offset — The access offset is out of the type. out of bounds, out of pocket, out of line. 🚩
• insn_track — it's right there in the struct, bestie! the Members section doesn't spell out a description for this one, so I'm not gonna make one up. she's declared, she's present, she's part of the squad. ✨

⚠️ quick vibe check: these are Debug statistics — counters about how analysis went, not data you act on. don't go reading meaning into them that isn't there, k? 🫶
