okay so bestie, welcome to the Kernel API Manual, section 9 — yes, the kernel one, not section 1, not section 3, we're in the big leagues now 🎀 this page is literally about uvd_v6_0_ring_test_ring, and ngl it's a tiny little function with one job and it does it. icon behavior.

🌸 NAME 🌸

uvd_v6_0_ring_test_ring — register write test, that's it, that's the whole vibe 🫶

heads up bestie: this is kernel API territory — section 9 — so these are for people writing/reading driver code, not for running from your shell. no man uvd_v6_0_ring_test_ring and chill 🫶

mwah 💋 that's the page! this little gem lives in ./drivers/gpu/drm/amd/amdgpu, dated October 2026, manual section 9 — so if you're citing it in a comment, that's the receipt, periodt ✨🎀
