STRUCT IWL_PRPH_SCRATCH(9)

💅 struct iwl_prph_scratch(9) — the Kernel API Manual, bestie edition 🎀

okay so. this is a page from the Kernel API Manual and it's literally all about struct iwl_prph_scratch — the peripheral scratch mapping. yes that's the whole NAME section, we're doing this 💖

---

✨ NAME ✨

struct iwl_prph_scratch — peripheral scratch mapping. that's it, that's the vibe, it maps the peripheral scratch, periodt 💅

---

🦋 SYNOPSIS 🦋

here's the whole struct, character for character, don't touch it, don't breathe on it:

struct iwl_prph_scratch {
    struct iwl_prph_scratch_ctrl_cfg ctrl_cfg;
    __le32 fseq_override;
    __le32 step_analog_params;
    __le32 reserved[8];
    struct iwl_context_info_dram_fseq dram;
 };

like, look at her. the way she's laid out. main character energy fr fr 🌸

🧚 Members 🧚

• ctrl_cfg — the control and configuration of prph scratch, i.e. the literal brain of the operation, lowkey the most important one here 👑
• fseq_override — FSEQ override parameters. yes. override. she's got opinions and she's allowed to have them 💀
• step_analog_params — STEP analog calibration values, which sounds very serious and important and honestly we respect it 🙈
• reserved — reserved. it's just... reserved. sitting there. looking pretty. don't ask questions, bestie ✨
• dram — firmware images addresses in DRAM. the actual addresses, in the actual DRAM, iconic behavior only 🫶

and if you see ./drivers/net/wireless/intel/i... down at the bottom with October 2026 next to it — mwah, that's the source/version-and-date footer, we stan her, we did not skip her, note it and move on bestie 💖</p>

so yeah. that's the page. struct iwl_prph_scratch(9) ate and left no crumbs, and now you know every single member plus the whole reading list. slay 🎀💜🦋🌸💅
