sdma_v6_0_ring_test_ring(9)

okay so bestie, we're cracking open the Kernel API Manual for sdma_v6_0_ring_test_ring(9), and honestly? It's giving "tiny but iconic async DMA vibe check" ✨💅

🎀 NAME 🎀

sdma_v6_0_ring_test_ring — simple async dma engine test. That's the whole name, no cap. 🫶

🦋 SYNOPSIS 🦋

int sdma_v6_0_ring_test_ring (struct amdgpu_ring *ring );

🌸 ARGUMENTS 🌸

• ring — the amdgpu_ring structure that holds ring information, periodt. That's the only arg, bestie. 🎀

💖 DESCRIPTION 💖

This function tests the DMA engine by using it to write a value to memory. Literally a little "go write something" field test for the ring. 👑

Returns 0 for success, and an error for failure — so check that return value, iykyk. 😭
