💅 uvd_v1_0_ib_test — test ib execution 🎀

okay so bestie, welcome to the uvd_v1_0_ib_test(9) page — literally the whole kernel API manual vibe, and yes we're doing this. this one lives in the radeon UVD corner of the kernel and honestly it's giving "small function, big feelings" energy. ✨

---

🌸 SYNOPSIS 🌸

int uvd_v1_0_ib_test (struct radeon_device *rdev , struct radeon_ring
*ring );

like, that's the whole signature. int return, two pointers, we move. 🫶

---

🦋 ARGUMENTS 🦋

• rdev — a radeon_device pointer, aka the radeon device we're working with. main character pointer fr.
• ring — a radeon_ring pointer, the ring we're poking at. iconic little struct.

---

✨ DESCRIPTION ✨

okay so what does this actually do? it tests if we can successfully execute an IB. that's it, that's the whole vibe — the function runs an IB through and checks whether it actually goes through, no cap. 💀 one job and it's doing it.
