STRUCT CS_DSP_ALG_REGION(9)

💖 struct cs_dsp_alg_region(9) 💖

okay so this is a page from the Kernel API Manual (yes, the actual kernel, we're being 🔥serious🔥 and 🎀cute🎀 at the same time) and it's all about struct cs_dsp_alg_region — literally the lil' map that says "this logical algorithm lives right here in DSP address space." bestie, it's giving treasure-map-for-firmware energy 🗺️✨

🌸 NAME 🌸

struct cs_dsp_alg_region — Describes a logical algorithm region in DSP address space 💅

---

🦋 SYNOPSIS 🦋

struct cs_dsp_alg_region {
    unsigned int alg;
    unsigned int ver;
    int type;
    unsigned int base;
 };

no cap, that's the whole struct. four little fields, absolute main character energy 👑

---

✨ Members ✨

• alg — the Algorithm id 🆔 (which algorithm this is, bestie)
• ver — the Expected algorithm version 📌 (like, the version you're expecting to show up — vibe check your firmware fr fr)
• type — the Memory region type 🗂️ (what kind of region we're talking about)
• base — the Address of region 📍 (where it actually sits in DSP address space — this is the coordinates, iykyk)

ngl, if you're poking at Cirrus DSP firmware internals, you're in the right ./include/linux/firmware/cirrus neighborhood 💀🔍

and that's the whole page, bestie — no crumbs left behind 🍓

🌸💜 k bye! this page was served up from ./include/linux/firmware/cirrus, dated October 2026, and it's struct cs_dsp_alg_region(9) all day every day — periodt 💅✨
