🦋 SYNOPSIS 🦋

enum hdcp_wired_protocol {

};

like, that's the whole enum, no cap — three vibes and that's it 🎀

✨ Constants ✨

• HDCP_PROTOCOL_INVALID — the "nope, not a thing" option 😭 this one means the HDCP adaptation protocol is invalid. it's giving placeholder energy, honestly.
• HDCP_PROTOCOL_HDMI — the HDMI adaptation of HDCP that's used on the port 👑 that's the one you're probably here for.
• HDCP_PROTOCOL_DP — the DP adaptation of HDCP used on the port 🦋 different cable, different adaptation, still iconic.

ok real talk: HDCP_PROTOCOL_INVALID literally means invalid — don't be out here treating it like a real protocol choice, bestie 💀
