ENUM SDCA_SMPU_CONTROLS(9)

🎀 NAME 🎀

Hey bestie 💖, welcome to enum sdca_smpu_controls(9) — your Kernel API Manual page for SDCA Controls for Smart Mic Processing Unit. That’s the manual name folded right in near the top, no boring header-line copy-paste, we’re doing this cute.

⭐ SYNOPSIS ⭐

No cap, this is the exact enum shape — spelling preserved, vibes immaculate:

enum sdca_smpu_controls {
    SDCA_CTL_SMPU_LATENCY ,
    SDCA_CTL_SMPU_TRIGGER_ENABLE ,
    SDCA_CTL_SMPU_TRIGGER_STATUS ,
    SDCA_CTL_SMPU_HIST_BUFFER_MODE ,
    SDCA_CTL_SMPU_HIST_BUFFER_PREAMBLE ,
    SDCA_CTL_SMPU_HIST_ERROR ,
    SDCA_CTL_SMPU_TRIGGER_EXTENSION ,
    SDCA_CTL_SMPU_TRIGGER_READY ,
    SDCA_CTL_SMPU_HIST_CURRENTOWNER ,
    SDCA_CTL_SMPU_HIST_MESSAGEOFFSET ,
    SDCA_CTL_SMPU_HIST_MESSAGELENGTH ,
    SDCA_CTL_SMPU_DTODTX_CURRENTOWNER ,
    SDCA_CTL_SMPU_DTODTX_MESSAGEOFFSET ,
    SDCA_CTL_SMPU_DTODTX_MESSAGELENGTH ,
    SDCA_CTL_SMPU_DTODRX_CURRENTOWNER ,
    SDCA_CTL_SMPU_DTODRX_MESSAGEOFFSET ,
    SDCA_CTL_SMPU_DTODRX_MESSAGELENGTH

};

Mwah 💅 — this iconic little page comes from source ./include/sound, dated October 2026, and it’s the enum sdca_smpu_controls(9) page in the Kernel API Manual. Byeee, go read some kernel headers 🫶✨
