🎀 ENUM SDCA_OT_CONTROLS(9) 🎀

okay so this is a page from the Kernel API Manual bestie, and it's all about enum sdca_ot_controls — the SDCA Controls for Output Terminal. yes it's niche. yes it's iconic. let's go 💅

💖 Constants 💖

okay so here's the thing — every single one of these is literally marked -- undescribed -- in the source, so I'm not gonna sit here and make stuff up about them (that would be lying and lying is not the vibe 🙈). Here's the full roster, all nine, no cap:

• SDCA_CTL_OT_USAGE — it's in the list, bestie! the docs say -- undescribed -- and honestly? same. 🫶
• SDCA_CTL_OT_LATENCY — also -- undescribed --. mystery queen.
• SDCA_CTL_OT_DATAPORT_SELECTOR — -- undescribed --, but the name is giving dataport selector energy 🔥
• SDCA_CTL_OT_MATCHING_GUID — -- undescribed --. matching! guid! slay.
• SDCA_CTL_OT_KEEP_ALIVE — -- undescribed --. keeping it alive fr fr ✨
• SDCA_CTL_OT_NDAI_STREAM — -- undescribed --. streamer behavior.
• SDCA_CTL_OT_NDAI_CATEGORY — -- undescribed --. categorize it ig.
• SDCA_CTL_OT_NDAI_CODINGTYPE — -- undescribed --. coding type, no comment.
• SDCA_CTL_OT_NDAI_PACKETTYPE — -- undescribed --. last but never least 👑

ngl the whole "undescribed" thing is a whole mood — the names are there, the prose is not. that's literally what the source says, so that's what you get 💀

🌸 Description 🌸

so what IS this? it's the Control Selectors for Output Terminal straight out of the SDCA specification v1.0, section 6.2.2.3. that's the whole flex. the spec is the main character here, we're just the enum living in its world 🧚
