STRUCT FAST_FORWARD_DATA(9)

💅 struct fast_forward_data(9) — like, the whole vibe

okay bestie, welcome to the Kernel API Manual ✨ — yes we're in the kernel docs together, hold my hand 🫶. This page is all about struct fast_forward_data, which is literally the data used by intel_pt_ff_cb(). That's it, that's the whole personality. Iconic, lowkey.

---

🌸 NAME 🌸

struct fast_forward_data — the data used by intel_pt_ff_cb(). no cap, that's the summary 💖

---

✨ SYNOPSIS ✨

here's the struct in all its glory, copied exactly, don't @ me:

struct fast_forward_data {
    uint64_t timestamp;
    uint64_t buf_timestamp;
 };

---

🎀 Members 🎀

• timestamp — the timestamp you're fast forwarding towards 🔥 like the destination, the moment we're heading to, main character timestamp energy.
• buf_timestamp — the buffer timestamp of the last buffer with trace data earlier than the fast forward timestamp 🌸 so, past data, but not too past. it's giving "last seen before the glow-up".
