ENUM SDCA_SAPU_CONTROLS(9)

💅 enum sdca_sapu_controls — SDCA Controls for Smart Amp Processing Unit 🎀

okay so bestie, this one is a kernel API manual page (yes, enum sdca_sapu_controls(9), that's the whole vibe) and it's literally just a big ol' list of control selectors. no cap, that's it. let's get into it ✨

---

✨ SYNOPSIS ✨

here's the whole enum, exactly as it lives, don't touch a single character bestie:

enum sdca_sapu_controls {
    SDCA_CTL_SAPU_LATENCY ,
    SDCA_CTL_SAPU_PROTECTION_MODE ,
    SDCA_CTL_SAPU_PROTECTION_STATUS ,
    SDCA_CTL_SAPU_OPAQUESETREQ_INDEX ,
    SDCA_CTL_SAPU_DTODTX_CURRENTOWNER ,
    SDCA_CTL_SAPU_DTODTX_MESSAGEOFFSET ,
    SDCA_CTL_SAPU_DTODTX_MESSAGELENGTH ,
    SDCA_CTL_SAPU_DTODRX_CURRENTOWNER ,
    SDCA_CTL_SAPU_DTODRX_MESSAGEOFFSET ,
    SDCA_CTL_SAPU_DTODRX_MESSAGELENGTH

};

🌸 Constants 🌸

okay so here's the thing — the source docs genuinely give us nothing for each of these. every single one says -- undescribed -- and honestly? iconic minimalism. 🫶 but i'm still gonna list all ten, because we do not skip entries in this house:

• SDCA_CTL_SAPU_LATENCY — -- undescribed --
• SDCA_CTL_SAPU_PROTECTION_MODE — -- undescribed --
• SDCA_CTL_SAPU_PROTECTION_STATUS — -- undescribed --
• SDCA_CTL_SAPU_OPAQUESETREQ_INDEX — -- undescribed --
• SDCA_CTL_SAPU_DTODTX_CURRENTOWNER — -- undescribed --
• SDCA_CTL_SAPU_DTODTX_MESSAGEOFFSET — -- undescribed --
• SDCA_CTL_SAPU_DTODTX_MESSAGELENGTH — -- undescribed --
• SDCA_CTL_SAPU_DTODRX_CURRENTOWNER — -- undescribed --
• SDCA_CTL_SAPU_DTODRX_MESSAGEOFFSET — -- undescribed --
• SDCA_CTL_SAPU_DTODRX_MESSAGELENGTH — -- undescribed --

ngl bestie, if you need the actual semantics of each one, the enum names are doing a lot of heavy lifting and the doc ain't helping 🙈 the real answer lives in the spec, not here.

💜 Description 💜

so what is this? these are the Control Selectors for Smart Amp Processing Unit straight outta the SDCA specification v1.0, Section 6.3.6.3. periodt. that's the whole description, she's short but she's serving ✨
