ENUM DMUB_CMD_IDLE_OPT_TYPE(9)

💅 enum dmub_cmd_idle_opt_type(9) — Kernel API Manual ✨

ok so bestie, welcome to the <pink>Kernel API Manual</pink> entry for enum dmub_cmd_idle_opt_type 🎀 — yes that's a whole mouthful, but it's basically the little enum that says "which idle optimization command is this?" 🦋

---

✨ NAME ✨

enum dmub_cmd_idle_opt_type — the idle optimization command type 💤👑

---

🌸 SYNOPSIS 🌸

enum dmub_cmd_idle_opt_type {
    DMUB_CMD__IDLE_OPT_DCN_RESTORE ,
    DMUB_CMD__IDLE_OPT_DCN_SAVE_INIT ,
    DMUB_CMD__IDLE_OPT_DCN_NOTIFY_IDLE ,
    DMUB_CMD__IDLE_OPT_SET_DC_POWER_STATE ,
    DMUB_CMD__IDLE_OPT_RELEASE_HW

};

---

🎀 Constants 🎀

ok so here's the thing — the original page literally just says <italic>-- undescribed --</italic> for every single one of these 😭 so I'm not gonna make stuff up, that would be so not the vibe. Here's the full set, exactly as listed, and yeah they're all marked undescribed no cap:

• DMUB_CMD__IDLE_OPT_DCN_RESTORE — -- undescribed -- 🙈
• DMUB_CMD__IDLE_OPT_DCN_SAVE_INIT — -- undescribed -- 🙈
• DMUB_CMD__IDLE_OPT_DCN_NOTIFY_IDLE — -- undescribed -- 🙈
• DMUB_CMD__IDLE_OPT_SET_DC_POWER_STATE — -- undescribed -- 🙈
• DMUB_CMD__IDLE_OPT_RELEASE_HW — -- undescribed -- 🙈

fr fr, that's all the source gives us for these five. Five constants, five shrugs. 💀
