STRUCT GUC_LIC(9)

💅 NAME 💅

struct guc_lic — the GuC LIC (Log-Init-Config) structure, bestie. That's it, that's the vibe ✨

🎀 SYNOPSIS 🎀

struct guc_lic {
    u32 magic;
  #define GUC_LIC_MAGIC                   0x8086900D;
    u32 version;
  #define GUC_LIC_VERSION_MASK_MAJOR              GENMASK(31, 16);
  #define GUC_LIC_VERSION_MASK_MINOR              GENMASK(15, 0);
  #define GUC_LIC_VERSION_MAJOR   1u;
  #define GUC_LIC_VERSION_MINOR   0u;
    u32 data_count;
    u32 data[];
 };

Like, copy it exactly, don't freestyle it, i'm literally begging 🙏

• magic — a magic number that GuC sets so you know this structure is holding valid info, no cap. It's magic = GUC_LIC_MAGIC. 🔥
• version — the version of this structure, and the major + minor numbers live as bit fields inside it. Cute little packing moment 💅
• data_count — how many dwords the data array contains. Count 'em.
• data — an array of dwords representing a list of LIC KLVs of type guc_klv_generic, with keys represented by guc_lic_type. Iconic little key-value moment 👑

🌸 Description 🌸

So the GUC populates this at log init time, and it's located in the log buffer memory allocation. That's the whole tea ☕ — it's GuC's little note-to-self, sitting right there in the allocation. 🦋
