✨ sdma_v5_2_gfx_stop(9) ✨

okay so bestie, welcome to the Kernel API Manual 💅 — this is the glow-up of sdma_v5_2_gfx_stop(9), and it's lowkey iconic.

🌸 NAME 🌸

sdma_v5_2_gfx_stop — stop the gfx async dma engines 🛑

Like, it literally shuts the whole vibe down. periodt.

---

🎀 SYNOPSIS 🎀

void sdma_v5_2_gfx_stop (struct amdgpu_device *adev , uint32_t inst_mask );

no cap, that's the whole signature. short king 🫶

---

💖 ARGUMENTS 💖

• adev — amdgpu_device pointer ✨ it's giving "here's your whole GPU, bestie."
• inst_mask — mask of dma engine instances to be disabled 🎯 Stop the gfx async dma ring buffers.

so yeah, you hand it the device and a mask, and the gfx async dma ring buffers get stopped. that's the assignment, and it ate. 🔥

🫶 friendly reminder: inst_mask is the mask of dma engine instances to be disabled — plural instances, so don't come at it with the wrong mask, iykyk.
