ENUM SDCA_PPU_CONTROLS(9)

💅 enum sdca_ppu_controls — the Kernel API Manual moment (yes it's enum sdca_ppu_controls(9), we stan a section 9 icon)

okay bestie, gather round 🎀 because today we're talking about enum sdca_ppu_controls, which is literally the SDCA Controls for Post Processing Unit. that's the whole name. that's the vibe. it's giving "short and mysterious" and honestly? iconic.

---

✨ SYNOPSIS ✨

enum sdca_ppu_controls {
    SDCA_CTL_PPU_LATENCY ,
    SDCA_CTL_PPU_POSTURENUMBER ,
    SDCA_CTL_PPU_POSTUREEXTENSION ,
    SDCA_CTL_PPU_HORIZONTALBALANCE ,
    SDCA_CTL_PPU_VERTICALBALANCE

};

like, look at that little family 😭 five members, all matching, all uppercase, no notes. slay.

🌸 Constants 🌸

so the manpage is out here giving us zero description for each of these (the original literally says -- undescribed -- for every single one, and I refuse to make stuff up about kernel internals, that's not the move 🙈). but here's the cast list anyway, each with the exact same "no description provided" energy:

• SDCA_CTL_PPU_LATENCY — -- undescribed -- 🫶 (the page really said "figure it out, bestie")
• SDCA_CTL_PPU_POSTURENUMBER — -- undescribed -- ✨
• SDCA_CTL_PPU_POSTUREEXTENSION — -- undescribed -- 🦋
• SDCA_CTL_PPU_HORIZONTALBALANCE — -- undescribed -- 💜
• SDCA_CTL_PPU_VERTICALBALANCE — -- undescribed -- 🌈

ngl, five constants and not a single blurb is a choice, but I'm not gonna invent behaviour that isn't in the source. that would be messy and also wrong. we respect the docs in this house 💅

🦋 Description 🦋

these are the Control Selectors for the Post Processing Unit, straight outta the SDCA specification v1.0, Section 6.3.5.3. periodt. that's the citation, that's where you go if you want the actual lore 📖✨
