ENUM IWL_MVM_AGG_STATE(9)

💅 enum iwl_mvm_agg_state(9) — the kernel API manual, but make it make sense

okay bestie, so this is a page about enum iwl_mvm_agg_state — literally the aggregation session state enum. it lives in the Kernel API Manual (that's the manual name, iykyk) and it's lowkey giving backstage-pass-to-the-BA-state-machine energy. let's get into it 🎀

---

✨ NAME ✨

enum iwl_mvm_agg_state — aggregation session state. that's the whole vibe. the enum that tells you where your aggregation session is at, emotionally 💅

---

✨ SYNOPSIS ✨

here's the shape of it, bestie — copy it exactly, no cap:

enum iwl_mvm_agg_state {
    IWL_AGG_OFF ,
    IWL_AGG_QUEUED ,
    IWL_AGG_STARTING ,
    IWL_AGG_ON ,
    IWL_EMPTYING_HW_QUEUE_ADDBA

};

---

✨ Constants ✨

these are the states, and each one is a little main character in the story of a BA session:

• IWL_AGG_OFF — aggregation is not used. we're off. not today. ✨
• IWL_AGG_QUEUED — the aggregation start work has been queued. like, it's in the group chat, it just hasn't been read yet 🫶
• IWL_AGG_STARTING — aggregation are starting (between start and oper). yes it's mid-transition, yes it's giving liminal space 🦋
• IWL_AGG_ON — aggregation session is up. we're LIVE, it's happening, slay 👑
• IWL_EMPTYING_HW_QUEUE_ADDBA — establishing a BA session — waiting for the HW queue to be empty from packets for this RA /TID. literally just sitting there waiting for the queue to clear out so we can move on 😭

---

✨ Description ✨

so this enum is the state machine of the BA agreement establishment / tear down. those states relate to a specific RA / TID. that's it, that's the whole deal — one tiny state machine tracking one very specific pairing 💖
