STRUCT PRI_SEQUENCE(9)

🦋 struct pri_sequence(9) — okay so this is from the Kernel API Manual, bestie

Hi hi hiii 💖 welcome to the page for struct pri_sequence, which is literally just… a sequence of pulses that all match one PRI. That's the whole vibe. It's giving "radar detector's little notebook" energy and honestly? Obsessed.

✨ NAME ✨

struct pri_sequence — a sequence of pulses matching one PRI 🎀

---

🌸 SYNOPSIS 🌸

struct pri_sequence {
    struct list_head head;
    u32 pri;
    u32 dur;
    u32 count;
    u32 count_falses;
    u64 first_ts;
    u64 last_ts;
    u64 deadline_ts;
 };

No gatekeeping here, this is the whole thing 💅

💜 MEMBERS 💜

• head — a list_head. That's it, that's the description, it's a list head fr fr 🫶
• pri — the pulse repetition interval (PRI) in usecs ✨
• dur — how long the sequence lasts, in usecs ⏳
• count — how many pulses are chillin' in this sequence 🔥
• count_falses — the number of pulses in this sequence that don't match 😭 like the leftovers, the ones who didn't get the invite
• first_ts — time stamp of the first pulse, in usecs 🎀
• last_ts — time stamp of the last pulse, in usecs 🌸
• deadline_ts — the deadline for when this whole sequence becomes invalid, and it's literally first_ts + dur 👑 (math! we love her!)

---

Lowkey important: everything timestamp-y and duration-y in here is measured in usecs. Not secs, not msecs. usecs. Don't embarrass yourself 🫶

Go read the detector one next, it's the main character energy to this struct's supporting role 💀✨
