amdgpu_devic..._reset_magic(9)

📦 version 7.3.1, in nixpkgs unstable

Okay bestie, welcome to the amdgpu_devic..._reset_magic(9) page in the Kernel API Manual — yes, the title is truncated like that, and yes, we’re still absolutely slaying. 💅✨

🌸 NAME 🌸

amdgpu_device_fill_reset_magic — writes reset magic to gart pointer. 🎀

✨ SYNOPSIS ✨

void amdgpu_device_fill_reset_magic (struct amdgpu_device *adev );

🦋 ARGUMENTS 🦋

  • adev — amdgpu_device pointer. 🫶

💖 DESCRIPTION 💖

Okay so here’s the tea: this function writes a reset magic value to the gart pointer in VRAM. The driver calls this function before a GPU reset. If the value is retained after a GPU reset, VRAM has not been lost. Some GPU resets may destroy VRAM contents. 😭

Bestie, that last part is important: some GPU resets can literally wipe VRAM contents, so the whole “did our magic value survive?” check is giving very much main-character energy. 🔥
