STRUCT IFS_DATA(9)

📦 version 7.3.1, in nixpkgs unstable

okay bestie, welcome to the Kernel API Manual, section 9. we are looking at struct ifs_data, and it is literally the lil’ bundle of attributes related to the intel IFS driver. no cap, this is the whole vibe. 🫶

🌸 NAME 🌸

struct ifs_data — the struct that holds attributes related to the intel IFS driver. periodt. 💖

✨ SYNOPSIS ✨

       struct ifs_data {
           int loaded_version;
           bool loaded;
           bool loading_error;
           int valid_chunks;
           int status;
           u64 scan_details;
           u32 cur_batch;
           u32 generation;
           u32 chunk_size;
           u32 array_gen;
           u32 max_bundle;
        };

🎀 Members 🎀

  • loaded_version — stores the currently loaded ifs image version. it’s giving “version receipt” energy. 🧾
  • loaded — tells you if a valid test binary has been loaded into the memory. yes, literally that check. 👑
  • loading_error — an error occurred on another CPU while loading the image. another CPU said “not me” 😭
  • valid_chunks — the number of chunks which could be validated. counting the good ones fr fr. 🔢
  • status — holds a simple status: pass / fail / untested. short king energy. 💀
  • scan_details — an opaque scan status code from h/w. h/w said “iykyk” 🙈
  • cur_batch — a number indicating the currently loaded test file. the current batch is main character. 🌟
  • generation — the IFS test generation enumerated by hardware. hardware is doing the sorting. 🔥
  • chunk_size — size of a test chunk. chunk said “I have a size” and slayed. 🍓
  • array_gen — test generation of array test. another generation, another vibe. 🌈
  • max_bundle — maximum bundle index. the ceiling. the limit. the final boss. 💜
