💖 amdgpu_uvd_ring_test_ib(9) 💖

okay so bestie, we're in the Kernel API Manual today and the main character is amdgpu_uvd_ring_test_ib ✨ no cap, this one's short and sweet but she's important.

🌸 NAME 🌸

amdgpu_uvd_ring_test_ib — literally just here to test ib execution 🎀

---

🦋 SYNOPSIS 🦋

int amdgpu_uvd_ring_test_ib (struct amdgpu_ring *ring , long timeout );

like… that's the whole vibe. two args, one int return, periodt 💅

---

✨ ARGUMENTS ✨

• ring — an amdgpu_ring pointer 🌀 she's your ring, your whole personality for this call
• timeout — timeout value in jiffies, or MAX_SCHEDULE_TIMEOUT ⏰ (iykyk, that second one means "wait basically forever")

---

💜 DESCRIPTION 💜

It tests if we can successfully execute an IB 🔥 that's it, that's the whole thing. lowkey iconic for how direct she is.

ngl bestie, this is a test — she's checking whether the IB actually goes through, not doing the fancy decode stuff herself. the real lore lives over in SEE ALSO 👀
