fw_trace_get_first(9)

✨ fw_trace_get_first(9) ✨

okay so this is a page from the Kernel API Manual bestie, and it's about fw_trace_get_first — literally the function that finds the very first valid entry in a trace 🎀

---

💖 NAME 💖

fw_trace_get_first — find first valid entry in trace

---

🌸 SYNOPSIS 🌸

void fw_trace_get_first (struct pvr_fw_trace_seq_data *trace_seq_data );

---

🦋 ARGUMENTS 🦋

• trace_seq_data — the trace sequence data. that's the whole vibe, it's just carrying the trace sequence data around 🫶

---

🔥 DESCRIPTION 🔥

so what it does: it skips over the invalid entries (usually the zero ones, ngl) and it skips the ROGUE_FW_SF_FIRST entries. like, not it just politely stepping around them 💅

but bestie, listen — if the trace has no valid entries at all, this function will exit with the trace index pointing to the end of the trace. and in that state, trace_seq_show will return an error. so like, don't be surprised when it errors, okay? 😭 that's the vibe check.
