STRUCT IWL_FW_INI_ERROR_DUMP_RANGE(9)

💅 NAME 💅

struct iwl_fw_ini_error_dump_range — range of memory

okay bestie, welcome to the struct iwl_fw_ini_error_dump_range(9) page from the Kernel API Manual ✨ this one's a kernel-doc struct, so it's short and sweet, but literally every field matters, so let's not skip a single one 🫶

🌸 SYNOPSIS 🌸

struct iwl_fw_ini_error_dump_range {
    __le32 range_data_size;
    union {
      __le32 internal_base_addr;
      __le64 dram_base_addr;
      __le32 page_num;
      struct iwl_fw_ini_fifo_hdr fifo_hdr;
      struct iwl_cmd_header fw_pkt_hdr;
    };
    __le32 data[];
 };

the way that's giving "one struct, five different vibes depending on context" 😭 like the union is lowkey the main character here, iykyk.

👑 MEMBERS 👑

• range_data_size — the size of this range, in bytes 💖 (yes, bytes, ngl keep your units straight fr)
• {unnamed_union} — anonymous 🙈 that's it, that's the entire description, it's an unnamed union and it has no handle bestie, mysterious queen behavior
• internal_base_addr — base address of internal memory range 🔥
• dram_base_addr — base address of dram monitor range ⭐
• page_num — page number of memory range 🎀
• fifo_hdr — fifo header of memory range 🦋
• fw_pkt_hdr — FW packet header of memory range 💜
• data — the actual memory ✨ the real payload, the moment we've all been waiting for 👑

heads up babes: everything above lives inside that anonymous union except range_data_size and data, so it's kind of a "pick your flavor" situation — that's exactly how the struct is spelled above, no cap 💅
