STRUCT IWL_TWT_OPERATION_CMD(9)

🌸 struct iwl_twt_operation_cmd(9) 🌸

okay so this is straight out of the Kernel API Manual, and it's literally the struct you use to kick off a TWT session from the driver side. bestie. it's giving "networking but make it scheduled." no cap.

✨ NAME ✨

struct iwl_twt_operation_cmd — initiate a TWT session from driver 💅

🎀 SYNOPSIS 🎀

struct iwl_twt_operation_cmd {
    __le32 link_id;
    __le32 twt_operation;
    __le64 target_wake_time;
    __le32 interval_exponent;
    __le32 interval_mantissa;
    __le32 minimum_wake_duration;
    u8 trigger;
    u8 flow_type;
    u8 flow_id;
    u8 twt_protection;
    u8 ndp_paging_indicator;
    u8 responder_pm_mode;
    u8 negotiation_type;
    u8 twt_request;
    u8 implicit;
    u8 twt_group_assignment;
    u8 twt_channel;
    u8 restricted_info_present;
    u8 dl_bitmap_valid;
    u8 ul_bitmap_valid;
    u8 dl_tid_bitmap;
    u8 ul_tid_bitmap;
 };

look at all those u8s. it's a whole little army. 🫶

🦋 Members 🦋

okay bestie, field by field, no skipping, this is the whole roster 👑

• link_id — the FW link id, like, the one you initiate the TWT on
• twt_operation — of type enum iwl_twt_operation_type
• target_wake_time — the TSF time to start the TWT ⏰ (yes, actual start time, not a vibe)
• interval_exponent — the exponent for the interval
• interval_mantissa — the mantissa for the interval (exp + mantissa = the interval math, iconic pairing)
• minimum_wake_duration — the minimum duration for the wake period
• trigger — is the TWT triggered or not
• flow_type — is the TWT announced (0) or not (1)
• flow_id — the TWT flow identifier 0 - 7
• twt_protection — is the TWT protected
• ndp_paging_indicator — is ndp 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 (STA), 0 for TWT response (AP)
• implicit — is TWT implicit
• twt_group_assignment — the TWT group assignment
• twt_channel — the TWT channel
• restricted_info_present — is this a restricted TWT
• dl_bitmap_valid — is DL (download) bitmap valid (restricted TWT)
• ul_bitmap_valid — is UL (upload) bitmap valid (restricted TWT)
• dl_tid_bitmap — DL TID bitmap (restricted TWT)
• ul_tid_bitmap — UL TID bitmap (restricted TWT)

ngl the last four are all "restricted TWT" coded, so if you're not doing restricted TWT they're just sitting there looking pretty 💀
