Supermicro_X10_AMD_V620_info.txt
Ubuntu grub kernel command line for amdgpu compatibility with V620 on Supermicro X10 motherboard:
intel_iommu=off iommu=off amdgpu.no_system_mem_limit=0 pci=realloc=off amdgpu.gpu_recovery=1 amdgpu.ppfeaturemask=0xfff73fff amdgpu.mcbp=0 amdgpu.rebar=1 amdgpu.pcie_p2p=0 amdgpu.use_xgmi_p2p=0
May require https://github.com/xCuri0/ReBarUEFI for compatibility with ReBAR if you have an older motherboard and the UEFI firmware needs the BIOS compatibility mode to be disabled.
I recommend making sure your motherboard supports ReBAR for compatibility with the V620 so you don't have to patch the UEFI firmware which can be very risky to do.
