STRUCT HL_ERROR_INFO(9)

okay so bestie, welcome to struct hl_error_info(9) from the Kernel API Manual — the little struct that holds all the receipts when an error happens. it's giving "error info main character energy," and honestly? iconic. ✨

💖 NAME 💖

struct hl_error_info — holds information collected during an error. that's the whole gig: one container for the error tea, no cap. 🫖

✨ SYNOPSIS ✨

here's the exact shape, bestie — every field stays exactly as it is, no edits, no vibes-based renaming:

struct hl_error_info {
    struct cs_timeout_info          cs_timeout;
    struct razwi_info               razwi_info;
    struct undefined_opcode_info    undef_opcode;
    struct page_fault_info          page_fault_info;
    struct hw_err_info              hw_err;
    struct fw_err_info              fw_err;
    struct engine_err_info          engine_err;
};

🌸 Members 🌸

okay so each member is a different flavor of "what went wrong" tea. sip carefully:

• cs_timeout — CS timeout error information. ⏰
• razwi_info — RAZWI information. 🌀
• undef_opcode — undefined opcode information. 🧩
• page_fault_info — page fault information. 📄
• hw_err — (fatal) hardware error information. yes, fatal is literally in the original, and it's highkey serious. 💀
• fw_err — firmware error information. 🔧
• engine_err — engine error information. ⚙️

reminder: hw_err is the one labeled (fatal). treat it with respect, fr fr. 💀
