✨ NAME ✨

okay so bestie, welcome to the sdma_v3_0_ring_test_ring(9) page from the Kernel API Manual 💖 this one is literally the simple async dma engine test, no cap.

sdma_v3_0_ring_test_ring — simple async dma engine test.

📜 SYNOPSIS 📜

int sdma_v3_0_ring_test_ring (struct amdgpu_ring *ring );

🎀 ARGUMENTS 🎀

• ring — an amdgpu_ring structure holding ring information. That’s the main character right there 👑 the whole ring vibe lives in this struct.

🔥 DESCRIPTION 🔥

okay so the move here is: test the DMA engine by using it to write a value to memory. It’s marked (VI). — that’s part of the tea, keep it 🫖✨

It returns 0 for success, and an error for failure. So if you get 0, slay 💅 if you get an error, that’s your vibe check saying something went sideways 😭
