STRUCT IWL_DRAM_REGIONS(9)

💖 STRUCT IWL_DRAM_REGIONS — the DRAM regions container structure ✨

okay so bestie, welcome to the struct iwl_dram_regions(9) page from the Kernel API Manual — yes that's the manual name, we're in the kernel docs now, put your hair up 🎀

🌸 SYNOPSIS 🌸

like, here's literally the whole shape of her, no edits:

struct iwl_dram_regions {
    struct iwl_dram_data drams[IPC_DRAM_MAP_ENTRY_NUM_MAX];
    struct iwl_dram_data prph_scratch_mem_desc;
    u8 n_regions;
 };

that's the vibe. that's the whole struct. iconic honestly 💅

✨ Members ✨

• drams — an array of several DRAM areas, and she's holding the pnvm and power reduction table payloads in there 🫶 like a little handbag for payloads, fr fr.
• prph_scratch_mem_desc — points to a structure that's allocated in dram, and its whole job is showing FW where all the payloads are 👑 lowkey the map, the GPS, the "you are here" sign for firmware.
• n_regions — the number of DRAM regions that were allocated. just the count. the receipts. the u8 of it all 💀

ngl bestie, that SEE ALSO list is a whole syllabus 😭 go read struct iwl_dram_data(9) first, it's giving prerequisite energy 🔥

mwah 💋 that's a wrap! this page came from ./drivers/net/wireless/intel/i... and it's dated October 2026 — so like, future energy ⭐ the manual name is still struct iwl_dram_regions(9) and she ate, periodt 🌈💜
