cs_dsp_stop(9)

✨ cs_dsp_stop(9) ✨

okay so bestie, welcome to the Kernel API Manual entry for cs_dsp_stop — yes that's the (9) section, we're in kernel-doc territory now, grab a boba and let's go 💅

---

🌸 NAME 🌸

cs_dsp_stop — stops the firmware. that's it. that's the job. she stops it 🛑

---

🦋 SYNOPSIS 🦋

void cs_dsp_stop (struct cs_dsp *dsp );

literally one call, returns void, no notes, no drama. iconic behaviour honestly 👑

---

🎀 ARGUMENTS 🎀

• dsp — pointer to the DSP structure. that's your DSP. the one you're stopping. give her the pointer and she'll handle the rest 🫶

---

💖 DESCRIPTION 💖

so here's the tea, bestie: memory will not be disabled, which means the firmware will remain loaded after this call. it's not a full teardown, it's more like... pressing pause on the vibe check, not deleting the whole playlist. no cap 🧚

tiny reminder bestie: stop ≠ unload. the firmware is still chilling in memory after this. don't @ me, that's literally what the description says 💀

and that's the page!! 💜 sign-off time: this little gem comes from the source tree at ./drivers/firmware/cirrus, dated October 2026, and she answers to the name cs_dsp_stop(9). mwah, go touch some firmware 🍓🎀
