 ### 6.2 Kernel Parameters (tested on Fedora 42)
 
 Add these boot parameters to enable unified memory while reserving a minimum of 4 GiB for the OS (max 124 GiB for iGPU):
 
-amd_iommu=pt amdgpu.gttsize=126976 ttm.pages_limit=32505856

-| `amd_iommu=off`              | Disables AMD IOMMU to reduce overhead for better performance               |
+| `iommu=pt`              | Sets IOMMU to "Pass-Through" mode. This helps performance, reducing overhead for both the RDMA NIC and the iGPU unified memory access.               |
 | `amdgpu.gttsize=126976`     | Caps GPU unified memory to 124 GiB; 126976 MiB ÷ 1024 = 124 GiB                            |
 | `ttm.pages_limit=32505856`  | Caps pinned memory to 124 GiB; 32505856 × 4 KiB = 126976 MiB = 124 GiB                     |
