amdgpu_devi...ce_isolation(9)

📦 version 7.3.1, in nixpkgs unstable

💖 amdgpu_device_enforce_isolation — the amdgpu_devi...ce_isolation(9) glow-up 💖

okay so bestie, welcome to the Kernel API Manual ✨ this one's a lil kernel function from the amdgpu fam and it's literally the bouncer at the club for the GFX block 🎀

🌸 NAME 🌸

amdgpu_device_enforce_isolation — enforce HW isolation 👑

✨ SYNOPSIS ✨

struct dma_fence * amdgpu_device_enforce_isolation (struct amdgpu_device
*adev , struct amdgpu_ring *ring , struct amdgpu_job *job );

🦋 ARGUMENTS 🦋

  • adev — the amdgpu device pointer, aka the main character of this whole situation 💅
  • ring — the HW ring the job is supposed to run on 🔥
  • job — the job which is about to be pushed to the HW ring, like it's about to walk the runway 🎀

🌈 DESCRIPTION 🌈

not me gatekeeping the GFX block 😭 this function makes sure that only one client at a time can use the GFX block. one. single. client. no sharing, no tag-teaming, no "can I bring my friend" energy. periodt 🫶

⭐ RETURN ⭐

it hands you back the dependency to wait on before the job can be pushed to the HW ✨ and heads up — the function is called multiple times until NULL is returned 🌀 so like, keep calling until it says "we're done here" 💀
