STRUCT IWL_DUMP_INI_MEM_OPS(9)

💅 struct iwl_dump_ini_mem_ops — the Kernel API manual, bestie edition

okay so picture this: it's struct iwl_dump_ini_mem_ops(9), it lives in the Kernel API Manual, and it is literally the blueprint for how the ini memory dump does its thing. think of it as the little group chat of function pointers that tells the dump code how to handle each region. main character energy, no cap. 🎀

✨ NAME ✨

struct iwl_dump_ini_mem_ops — ini memory dump operations. that's it, that's the vibe. 💖

---

🌸 SYNOPSIS 🌸

here's the whole struct, verbatim, do not touch, she's perfect:

struct iwl_dump_ini_mem_ops {
    u32 (*get_num_of_ranges)(struct iwl_fw_runtime *fwrt, struct
iwl_dump_ini_region_data *reg_data);
    u32 (*get_size)(struct iwl_fw_runtime *fwrt, struct
iwl_dump_ini_region_data *reg_data);
    void *(*fill_mem_hdr)(struct iwl_fw_runtime *fwrt, struct
iwl_dump_ini_region_data *reg_data, void *data, u32 data_len);
    int (*fill_range)(struct iwl_fw_runtime *fwrt, struct
iwl_dump_ini_region_data *reg_data, void *range, int idx);
    bool requires_nic_access;
};

🦋 Members 🦋

• get_num_of_ranges — returns the number of memory ranges in the region. she's doing a headcount, respectfully. 🔥
• get_size — returns the total size of the region. the whole thing, the full picture, the entire vibe check. ✨
• fill_mem_hdr — fills region type specific headers and returns pointer to the first range or NULL if failed to fill headers. so like, if the headers don't fill, you get NULL and that's your sign 😭
• fill_range — copies a given memory range into the dump. Returns the size of the range or negative error value otherwise. slays when it works, hands you a negative number when it doesn't 💀
• requires_nic_access — indicates to dump only if NIC access was acquired. like a bouncer at the club, no NIC access, no dump, periodt. 👑

ngl bestie, this is a struct of function pointers — every one of them has to be wired up correctly or the dump gets messy. keep the signatures exactly as written, fr fr. 🙈

okay that's the whole page, mwah 💋 this iconic little number came from ./drivers/net/wireless/intel/i... and it's dated October 2026, and yes the page header is still struct iwl_dump_ini_mem_ops(9) because we don't disrespect the title. bye bestie, go dump some memory responsibly 🍓🧚💜
