STRUCT IWL_DRAM_INFO(9)

💖 NAME 💖

struct iwl_dram_info — the DRAM fragments allocation struct, bestie ✨

So this is a page from the Kernel API Manual (struct iwl_dram_info(9)), and it's literally just a struct that's all about DRAM fragments allocation. No cap. Let's get into it 💅

---

🌸 SYNOPSIS 🌸

struct iwl_dram_info {
    __le32 first_word;
    __le32 second_word;
    struct iwl_buf_alloc_cmd dram_frags[IWL_FW_INI_ALLOCATION_NUM - 1];
 };

Look at her. Three members. Main character energy, honestly 🎀

---

🦋 Members 🦋

• first_word — a magic word value ✨ like, literally a magic word, that's what it is
• second_word — also a magic word value 🪄 (yes, another one, we stan a two-magic-word situation)
• dram_frags — the DRAM fragmentaion detail 🍓 this is where the actual fragment info lives, iykyk

---

👑 Description 👑

Okay so here's the vibe: the driver will fill in the first 1K(+) of the pointed DRAM fragment 💾 that's the whole bit. She's a straightforward queen, no drama, no secrets 🌈

ngl bestie, if you're reading this page you were probably already deep in the iwlwifi debug headers, and honestly? respect 😭💀

okay that's the whole page, mwah 💋 this one came from ./drivers/net/wireless/intel/i... — October 2026 edition, filed under struct iwl_dram_info(9) 🧚‍♀️ slay, go fill in that first 1K(+) of DRAM fragment, periodt 🌟
