ENUM DPU_ENC_SPLIT_ROLE(9)

💅 enum dpu_enc_split_role(9) — a Kernel API Manual moment ✨

okay so bestie, welcome to the Kernel API Manual, and buckle up because this one is literally about who's in charge 👑

🌸 NAME 🌸

enum dpu_enc_split_role — the role a physical encoder plays in a split-panel configuration, where one panel is the master and the others are slaves. Masters have extra responsibilities, like managing the VBLANK IRQ. 🎀

✨ SYNOPSIS ✨

enum dpu_enc_split_role {
    ENC_ROLE_SOLO ,
    ENC_ROLE_MASTER ,
    ENC_ROLE_SLAVE

};

like, that's the whole enum, no cap 🫶

👑 Constants 👑

• ENC_ROLE_SOLO — the one and only panel, periodt. This encoder is the master, main character energy, no co-stars. ⭐
• ENC_ROLE_MASTER — this encoder is the master of a split panel config. it's giving leadership, it's giving VBLANK IRQ management duties 💅
• ENC_ROLE_SLAVE — this encoder is not the master of a split panel config. supportive role, still iconic, just not the one running the group chat 🙈
