xe_kunit_hel...ve_test_init(9)

✨ NAME ✨

xe_kunit_helper_xe_device_live_test_init — okay so this is the function that gets a &xe_device all prepped and ready for a live KUnit test 🎀

So this page is from the Kernel API Manual (yes, that's the manual name, we're being official today 💅), and the star of the show is xe_kunit_helper_xe_device_live_test_init.

---

🌸 SYNOPSIS 🌸

int xe_kunit_helper_xe_device_live_test_init (struct kunit *test );

Literal icon behaviour, no cap.

---

🦋 ARGUMENTS 🦋

• test — the kunit where the live xe_device is gonna get used. That's it, that's the whole argument, bestie 💖

---

🔥 DESCRIPTION 🔥

Okay so here's the vibe: this function expects a pointer to the xe_device sitting in test.param_value, exactly like it's prepared by xe_pci_live_device_gen_param, and then it stores that pointer as kunit.priv so your test code can go grab it whenever it needs it. Very main character of it 🫶

Then it makes sure the device is not wedged, and after that it resumes it — the whole point being so you don't end up waking the device up from inside your test. It uses a deferred cleanup action to release a runtime_pm reference, so that reference gets handled for you. Slay.

Also, good to know: this function can be used as a custom implementation of kunit_suite.init. And it uses KUNIT_ASSERT to detect any failures — so if something's off, it's gonna assert, not silently vibe through it 😭

---

⭐ RETURN ⭐

Always 0. Iconic, consistent, zero drama 💀
