💅 cs_dsp_wseq_init(9) — the Kernel API Manual glow-up ✨

okay so bestie, welcome to the Kernel API Manual entry for cs_dsp_wseq_init(9) — yes that's the manual name, we're being fancy today 🎀. This is the lil function that gets your write sequences all set up and ready to slay inside the DSP firmware you already loaded. Let's get into it 💖

✨ NAME ✨

cs_dsp_wseq_init — Initialize write sequences contained within the loaded DSP firmware 🌸

Like, the firmware's already loaded, right? This is the part where we go "okay bestie, wake up" to the write sequences chillin' inside it 🦋

🌈 SYNOPSIS 🌈

int cs_dsp_wseq_init (struct cs_dsp *dsp , struct cs_dsp_wseq *wseqs ,
unsigned int num_wseqs );

look at her. iconic signature. no notes 💅

💜 ARGUMENTS 💜

  • dsp — Pointer to DSP structure 🎀 — you know, the whole DSP situation itself.
  • wseqs — List of write sequences to initialize ✨ — this is the lineup of write sequences we're about to bring to life.
  • num_wseqs — Number of write sequences to initialize 🔥 — how many of them are in that list, bestie. Count carefully.

👑 RETURN 👑

Zero for success 🎉, a negative number on error 😭. That's it. That's the whole vibe check.

fr fr: if you get a negative number back, something did not go off. Do not ignore it 🙈

mwah 💋 that's the page. sourced from ./drivers/firmware/cirrus, dated October 2026, and yeah — the header and footer both said cs_dsp_wseq_init(9), so we said it too, periodt 💅✨
