amdgpu_devi..._iommu_remap(9)

📦 version 7.3.1, in nixpkgs unstable

💅 amdgpu_device_check_iommu_remap(9) — the kernel API manual, but make it make sense

okay so bestie, you found the amdgpu_devi..._iommu_remap(9) page in the Kernel API Manual (yes the title is truncated, no that's not a typo, that's just how the man page ships, iykyk) 💖

✨ NAME ✨

amdgpu_device_check_iommu_remap — literally just checks if DMA remapping is enabled. that's the whole vibe check 🦋

🌸 SYNOPSIS 🌸

bool amdgpu_device_check_iommu_remap (struct amdgpu_device *adev );

short, sweet, returns a bool. no cap. ✨

🎀 ARGUMENTS 🎀

  • adev — an amdgpu_device pointer. that's it. that's the whole argument. it's giving "one job and it ate" 💅

🧚 DESCRIPTION 🧚

so the function returns whether the IOMMU remapping bar address is a thing — i.e. it's the check for "is DMA remapping enabled?" 🫶

fr fr that's the entire description in the original, so I'm not gonna invent extra lore for you. it checks, it returns, it slays. periodt. 👑
