STRUCT IWL_DHC_TWT_OPERATION(9)

🎀 struct iwl_dhc_twt_operation(9) 🎀

okay bestie, this is a page from the Kernel API Manual, and it's all about struct iwl_dhc_twt_operation — literally the struct that triggers a TWT operation. no cap. let's get into it 💅

---

✨ NAME ✨

struct iwl_dhc_twt_operation — trigger a TWT operation. that's it, that's the whole vibe 🦋

---

🌸 SYNOPSIS 🌸

here's the whole struct, copied exactly, do not touch:

struct iwl_dhc_twt_operation {
    __le32 mac_id;
    __le32 twt_operation;
    __le64 target_wake_time;
    __le32 interval_exp;
    __le32 interval_mantissa;
    __le32 min_wake_duration;
    u8 trigger;
    u8 flow_type;
    u8 flow_id;
    u8 protection;
    u8 ndo_paging_indicator;
    u8 responder_pm_mode;
    u8 negotiation_type;
    u8 twt_request;
    u8 implicit;
    u8 twt_group_assignment;
    u8 twt_channel;
    u8 reserved;
 };

look at all those fields, she's serving structure 🔥

💖 Members 💖

okay so every single member, one by one, no skipping (i would never):

• mac_id — the mac Id on which to trigger TWT operation. like, which mac are we even doing this on, yk?
• twt_operation — see enum iwl_dhc_twt_operation_type. go look at the enum, bestie 👀
• target_wake_time — when should we be on channel. that's the whole question, whennnn ⏰
• interval_exp — the exponent for the interval.
• interval_mantissa — the mantissa for the interval. her and interval_exp are literally a matched set 🫶
• min_wake_duration — the minimum duration for the wake period.
• trigger — is the TWT triggered or not. yes or no bestie, pick one 🎀
• flow_type — is the TWT announced or not.
• flow_id — the TWT flow identifier from 0 to 7. so valid range is 0 to 7, remember that 😌
• protection — is the TWT protected.
• ndo_paging_indicator — is ndo_paging_indicator set.
• responder_pm_mode — is responder_pm_mode set.
• negotiation_type — if the responder wants to doze outside the TWT SP.
• twt_request — 1 for TWT request, 0 otherwise. 1 or 0, iconic binary behaviour ✨
• implicit — is TWT implicit.
• twt_group_assignment — the TWT group assignment.
• twt_channel — the TWT channel.
• reserved — reserved. she's reserved. we don't ask 💀

ngl this is lowkey just a struct, so there's no sneaky undefined behaviour here — but do respect that flow_id range of 0 to 7, and keep reserved reserved. respect her boundaries 🙈

okay that's the page!! final sign-off bestie: this one comes from ./drivers/net/wireless/intel/i... and it's dated October 2026, filed under struct iwl_d...wt_operation(9). mwah, go trigger some TWT operations 💋🌸✨
