# After editing, regenerate GRUB:
# sudo grub2-mkconfig -o /boot/grub2/grub.cfg
# Then reboot.

iommu=pt amdgpu.gttsize=60416 ttm.pages_limit=15466496
#
# For 128GB system (Framework Desktop, GMKtec EVO X2):
# iommu=pt amdgpu.gttsize=126976 ttm.pages_limit=32505856
#
# Parameter explanation:
# iommu=pt - IOMMU passthrough, reduces memory access latency
# amdgpu.gttsize=N - Max GPU-addressable system RAM in MiB (total - 4GB reserve)
# ttm.pages_limit=N - Max pinnable 4K pages (gttsize_MiB * 256)
