ENUM PANTHOR_GROUP_STATE(9)

Hey bestie! Welcome to enum panthor_group_state(9) — the Kernel API Manual page for the scheduling group state enum, and she is iconic. 💅 This is the enum that tracks a scheduling group’s state, and every single state is listed below. No skips. No cap. 🫶

🌸 NAME 🌸

enum panthor_group_state — Scheduling group state. That’s the whole vibe, periodt. ✨

✨ SYNOPSIS ✨

Okay so the synopsis is literally this enum, bestie. Exact energy, no edits:

enum panthor_group_state {
    PANTHOR_CS_GROUP_CREATED ,
    PANTHOR_CS_GROUP_ACTIVE ,
    PANTHOR_CS_GROUP_SUSPENDED ,
    PANTHOR_CS_GROUP_TERMINATED ,
    PANTHOR_CS_GROUP_UNKNOWN_STATE

};

That’s the whole shape. The constants themselves are down below, and yes, there are five. 🎀

🎀 Constants 🎀

Here’s the vibe check for each constant, all five, right in order:

• PANTHOR_CS_GROUP_CREATED — Group was created, but not scheduled yet. She exists, she’s just not on the schedule. 💖
• PANTHOR_CS_GROUP_ACTIVE — Group is currently scheduled. Main character energy: she’s on the schedule right now. 🔥
• PANTHOR_CS_GROUP_SUSPENDED — Group was scheduled at least once, but is inactive/suspended right now. Been there, done that, currently chilling. 😴
• PANTHOR_CS_GROUP_TERMINATED — Group was terminated. Can no longer be scheduled. The only allowed action is a destruction. It’s giving final-boss exit. 💀
• PANTHOR_CS_GROUP_UNKNOWN_STATE — Group is an unknown state. The FW returned an inconsistent state. The group is flagged unusable and can no longer be scheduled. The only allowed action is a destruction.

When that happens, we also schedule a FW reset, to start from a fresh state. 🚨
