i915_perf_destroy_locked(9)

💖 NAME 💖

Okay so this is the i915_perf_destroy_locked(9) page from the Kernel API Manual, and it does exactly what it says on the tin: destroy an i915 perf stream. Periodt 💅

---

✨ SYNOPSIS ✨

The whole vibe is literally this one line, bestie:

void i915_perf_destroy_locked (struct i915_perf_stream *stream );

---

🎀 ARGUMENTS 🎀

• stream — an i915 perf stream. That's the one getting the cleanup treatment 🫶

---

💅 DESCRIPTION 💅

So i915_perf_destroy_locked() frees all resources associated with the given i915 perf stream, and it disables any associated data capture in the process. Cleanup queen energy, no cap ✨

---

🫶 NOTE 🫶

Heads up, bestie: the gt->perf.lock mutex has been taken to serialize with any non-file-operation driver hooks. That's the whole note — iconic lock behavior, iykyk 🔥
