ENUM SDCA_MFPU_CONTROLS(9)

💅 enum sdca_mfpu_controls(9) — Kernel API Manual 🎀

okay bestie, sit down, hydrate, and get ready, because we're looking at enum sdca_mfpu_controls from the Kernel API Manual. yes, the Kernel API Manual, that's the whole vibe of this page. let's go ✨

---

🌸 NAME 🌸

enum sdca_mfpu_controls — the SDCA Controls for Multi-Function Processing Unit. that's it, that's the whole name. main character energy fr 💖

---

🦋 SYNOPSIS 🦋

    SDCA_CTL_MFPU_BYPASS ,
    SDCA_CTL_MFPU_ALGORITHM_READY ,
    SDCA_CTL_MFPU_ALGORITHM_ENABLE ,
    SDCA_CTL_MFPU_LATENCY ,
    SDCA_CTL_MFPU_ALGORITHM_PREPARE ,

    SDCA_CTL_MFPU_AE_NUMBER ,
    SDCA_CTL_MFPU_AE_CURRENTOWNER ,
    SDCA_CTL_MFPU_AE_MESSAGEOFFSET ,
    SDCA_CTL_MFPU_AE_MESSAGELENGTH

};

look at her. twelve constants. absolutely ate 💅

🧚 Constants 🧚

so here's the thing, bestie — the source literally says -- undescribed -- for every single one of these. not me making it up, that's genuinely what's in there 😭 so no cap, here's the full lineup with zero extra lore attached:

• SDCA_CTL_MFPU_BYPASS — -- undescribed -- 🙈
• SDCA_CTL_MFPU_ALGORITHM_READY — -- undescribed -- 🙈
• SDCA_CTL_MFPU_ALGORITHM_ENABLE — -- undescribed -- 🙈
• SDCA_CTL_MFPU_LATENCY — -- undescribed -- 🙈
• SDCA_CTL_MFPU_ALGORITHM_PREPARE — -- undescribed -- 🙈
• SDCA_CTL_MFPU_CLUSTERINDEX — -- undescribed -- 🙈
• SDCA_CTL_MFPU_CENTER_FREQUENCY_INDEX — -- undescribed -- 🙈
• SDCA_CTL_MFPU_ULTRASOUND_LEVEL — -- undescribed -- 🙈
• SDCA_CTL_MFPU_AE_NUMBER — -- undescribed -- 🙈
• SDCA_CTL_MFPU_AE_CURRENTOWNER — -- undescribed -- 🙈
• SDCA_CTL_MFPU_AE_MESSAGEOFFSET — -- undescribed -- 🙈
• SDCA_CTL_MFPU_AE_MESSAGELENGTH — -- undescribed -- 🙈

ngl it's giving "the docs said ✨mystery✨". all twelve constants are listed above exactly as the page has them, and the page's own description for each one is -- undescribed --. that's the whole tea, don't come for me 🫶

👑 Description 👑

these are the Control Selectors for the Multi-Function Processing Unit, straight out of the SDCA specification v1.0 Section 6.3.3.4. that's the citation, that's the source, iconic behavior honestly ⭐
