STRUCT CS_DSP_REGION(9)

✨ struct cs_dsp_region(9) ✨

okay bestie, welcome to the Kernel API Manual 💖 — this one's a lil struct from the Linux kernel docs and she's honestly so simple she's iconic. like, two fields. two. we love a low-maintenance queen 👑

🌸 NAME 🌸

struct cs_dsp_region — literally describes a logical memory region in DSP address space 🎀

🦋 SYNOPSIS 🦋

struct cs_dsp_region {
    int type;
    unsigned int base;
};

that's it. that's the whole struct. no cap, she's tiny 💅

🫶 Members 🫶

so there's exactly two members and honestly? main character energy for both:

• type — the memory region type 🏷️ like, what kind of region are we even talking about here
• base — the address of the region 📍 like, where it lives. its little home address in DSP address space 🏠

🔥 SEE ALSO 🔥

the whole friend group shows up in the kernel file ./include/linux/firmware/cirrus/cs_dsp.h — go say hi to:

• struct cs_dsp_alg_region(9)
• struct cs_dsp_coeff_ctl(9)
• struct cs_dsp(9)
• struct cs_dsp_client_ops(9)
• struct cs_dsp_wseq(9)
• struct cs_dsp_chunk(9)
• cs_dsp_chunk(9)
• cs_dsp_chunk_end(9)
• cs_dsp_chunk_bytes(9)
• cs_dsp_chunk_valid_addr(9)

(yes struct cs_dsp_chunk(9) and cs_dsp_chunk(9) both get a mention — they're different besties, don't @ me 🙈)

ngl the source for all this is ./include/linux/firmware/cirrus, and it's stamped October 2026 and titled struct cs_dsp_region(9) — so like, cite her properly or whatever 💀

k that's the whole page, you ate that 🍓 mwah 💜✨
