💖 amdgpu_ib_ring_tests(9) — Kernel API Manual 💖

hiiii bestie 🫶 welcome to the amdgpu_ib_ring_tests(9) page in the Kernel API Manual. This is the kernel-side vibe check for IBs on the rings, and yes we're keeping every detail. no cap. ✨

✨ NAME ✨

amdgpu_ib_ring_tests — test IBs on the rings 💅

🌸 SYNOPSIS 🌸

int amdgpu_ib_ring_tests (struct amdgpu_device *adev );

🎀 ARGUMENTS 🎀

• adev — amdgpu_device pointer 🫶

🦋 DESCRIPTION 🦋

Okay so the whole tea: this function tests an IB (Indirect Buffer) on each ring. If the test fails, it disables the ring — like, that ring is not invited to the party anymore 💀.

It returns 0 on success, and it returns error if the primary GFX ring IB test fails. That's the important bit, bestie — primary GFX ring failure is the one that gives error back. 🔥
