oa_put_render_ctx_id(9)

💅 oa_put_render_ctx_id(9) 💅

ok so this is a page from the Kernel API Manual, bestie — it's literally called oa_put_render_ctx_id(9) and it's the cleanup queen of the i915 perf world 🎀

---

✨ NAME ✨

oa_put_render_ctx_id — the counterpart to oa_get_render_ctx_id that releases the hold 🫶

---

🦋 SYNOPSIS 🦋

void oa_put_render_ctx_id (struct i915_perf_stream *stream );

---

🌸 ARGUMENTS 🌸

• stream — an i915-perf stream that was opened for OA metrics ✨

---

💖 DESCRIPTION 💖

ok so picture this: if anything needed doing to make sure the context HW ID would stay valid for the whole lifetime of the stream, then this is where that gets undone. like, oa_get_render_ctx_id did the thing, and this function is the "ok we're done here, undoing the thing" moment 💅 no cap, that's it, that's the whole vibe.
