STRUCT US144MKII_FRAME_PATTERN_OBSERVER(9)

✨ struct us144mkii_frame_pattern_observer 💅

okay so this is a page from the Kernel API Manual, section 9, and bestie, it's giving "tiny struct, big responsibilities" energy. we're talking about struct us144mkii_frame_pattern_observer — the little state blob that keeps track of dynamic feedback patterns. that's it, that's the whole vibe. 🎀

---

🌸 NAME 🌸

struct us144mkii_frame_pattern_observer — literally the state for dynamic feedback patterns, no cap.

---

🦋 SYNOPSIS 🦋

struct us144mkii_frame_pattern_observer {
    unsigned int sample_rate_khz;
    unsigned int base_feedback_value;
    int feedback_offset;
    unsigned int full_frame_patterns[5][8];
    unsigned int current_index;
    unsigned int previous_index;
    bool sync_locked;
 };

look at her. seven members. absolutely iconic. 👑

💖 Members 💖

• sample_rate_khz — the current sample rate, in kHz. that's the number, in kHz, right now. ✨
• base_feedback_value — the nominal feedback value for whatever the current rate happens to be. the baseline. the default. the "you had one job" number.
• feedback_offset — an offset used to align the feedback value range. it's the nudge that makes the range line up, and honestly? same. 🫶
• full_frame_patterns — a 2D array of pre-calculated packet size patterns. yes bestie, pre-calculated, we are not doing that math live. declared as unsigned int full_frame_patterns[5][8];, so that's 5 by 8 of pure precomputed goodness. ⭐
• current_index — the current index into the pattern array. the now index, if you will. 📍
• previous_index — the previous index, used for state tracking. she remembers where you've been. 💀
• sync_locked — a flag indicating whether the pattern has locked to the stream. true means locked in, false means we're still looking for the beat. 🔥

🌈 SEE ALSO 🌈

lowkey you have to check these out, they're all in the kernel file ./sound/usb/usx2y/us144mkii.h and they're all part of the same friend group:

• struct tascam_card(9)
• tascam_free_urbs(9)
• tascam_alloc_urbs(9)
• tascam_stop_work_handler(9)
• tascam_midi_in_urb_complete(9)
• tascam_midi_out_urb_complete(9)
• tascam_create_midi(9)
• tascam_create_controls(9)

go read them. iykyk. 📚✨

no notes, no bugs listed here, just a very well-behaved little struct doing her thing. main character energy only. 👑

okay that's the whole page, bestie — shipped from ./sound/usb/usx2y, dated October 2026, and yes the header still says struct us14...ern_observer(9) because the terminal truncated it and we respect the truncation. periodt. 💜🎀
