sst_start_mrfld(9)

💅 sst_start_mrfld(9) — like, the kernel API manual bestie ✨

okay so we're in the kernel API manual, section 9, and today's main character is sst_start_mrfld 🎀 literally the function that gets the SST DSP up and running. buckle up, it's a short one but it ate. 🫶

✨ NAME ✨

sst_start_mrfld — start the SST DSP processor 👑 no cap, that's the whole job.

---

🌸 SYNOPSIS 🌸

int sst_start_mrfld (struct intel_sst_drv *sst_drv_ctx );

it's giving "one argument, returns an int, knows exactly what it wants" energy 💅

---

🦋 ARGUMENTS 🦋

• sst_drv_ctx — the intel_sst_drv context pointer, aka the whole vibe of the driver handed over in one struct pointer. she needs it, she uses it, that's the arrangement 💖

---

🧚 DESCRIPTION 🧚

so basically this bad boy starts the DSP on MERRIFIELD platforms 🔥 that's it, that's the function. short, sweet, iconic. the DSP was sitting there all "🥺" and then sst_start_mrfld shows up and now it's running. main character energy fr fr.

no extra parameters, no secret clauses, no caveats hiding in the fine print — the description says it starts the DSP on MERRIFIELD and we're not gonna invent anything else, because that would be lying and lying is not slay 🙈
