STRUCT ISST_CORE_POWER(9)

✨ NAME ✨

okay bestie, welcome to the Kernel API Manual page for struct isst_core_power(9) 💖 the NAME is literally struct isst_core_power — Structure to get/set core_power feature. no cap, that's the whole assignment: one struct, one job, get/set that core_power feature energy. 🫶

🌸 SYNOPSIS 🌸

so the shape of this little icon is:

       struct isst_core_power {
           __u8 get_set;
           __u8 socket_id;
           __u8 power_domain_id;
           __u8 enable;
           __u8 supported;
           __u8 priority_type;
        };

🧑‍🤝‍🧑 Members 🧑‍🤝‍🧑

okay, meet the cast of fields — every single one is important, don't skip the “boring” ones, they're all eating:

• get_set — 0: Get, 1: Set — yes, it's literally the get-or-set switch, main character energy 🔁
• socket_id — Socket/package id — which socket/package we're talking about 🧩
• power_domain_id — Power Domain id — the power domain's id, periodt ⚡
• enable — Feature enable status — is the feature enabled or not, the vibe check ✅
• supported — Power domain supports SST_CP interface — lowkey the compatibility receipt 🧾
• priority_type — Priority type for the feature (ordered/proportional) — ordered or proportional, those are the choices, iykyk 🎚️

💅 Description 💅

so this struct is the whole Structure to get/set core_power feature state using IOCTL ISST_IF_CORE_POWER_STATE. literally, that's the move: you use the IOCTL ISST_IF_CORE_POWER_STATE to get or set the core_power feature state, and this struct is the little messenger bag carrying the details 👜✨ obsessed, honestly.
