💅 cs_dsp_mock_wmfw_add_data_block — the kernel API manual, bestie edition

okay so this is the page for cs_dsp_mock...d_data_block(9) — yes the header is literally abbreviated like that, she's mysterious, she's iconic, that's just how the kernel do. anyway. welcome to the wmfw mock builder lore 🎀

✨ NAME ✨

cs_dsp_mock_wmfw_add_data_block — Add a data block to the wmfw file. that's it, that's the whole job, and she does it flawlessly 💅

🌸 SYNOPSIS 🌸

void cs_dsp_mock_wmfw_add_data_block (struct cs_dsp_mock_wmfw_builder
*builder , int mem_region , unsigned int mem_offset_dsp_words , const
void *payload_data , size_t payload_len_bytes );

like… look at her. five arguments, returns void, zero drama. no cap. ✨

🦋 ARGUMENTS 🦋

  • builder — Pointer to struct cs_dsp_mock_bin_builder. (yes bestie the original really does say cs_dsp_mock_bin_builder here — I'm not touching it, that's canon, copy it exactly as it is and don't @ me 🙈)
  • mem_region — Memory region for the block. an int. which region are we living in today 👑
  • mem_offset_dsp_words — Offset to start of destination in DSP words. not bytes, words — DSP words, respectfully. unsigned int. don't mix them up fr fr 💀
  • payload_data — Pointer to buffer containing the payload data. const void *, so we're looking, not touching 🫶
  • payload_len_bytes — Length of payload data in bytes. a size_t. note the units flip from the offset arg — words over there, bytes over here — and honestly that's the main character energy of this whole function ⭐
like, lowkey the vibe check here is: mem_offset_dsp_words is words, payload_len_bytes is bytes. keep them straight and you're slaying. mix them up and… 😭

💜 SEE ALSO 💜

Kernel file ./drivers/firmware/cirrus/test/cs_dsp_mock_wmfw.c — that's the source, go read her, she's right there 🌈

and the whole friend group:

they all ate, honestly. go hang with them next 💅

okay and finally, the little sign-off at the bottom of the page 📜 — this one lives in the kernel source tree under ./drivers/firmware/cirrus/test, it's dated October 2026, and it's filed under cs_dsp_mock...d_data_block(9). periodt. 💖🧚‍♀️
