The number of nodes will exceed 16(2^4) for arm64 server(such as phytium cpu), so we should change the max number of nodes to adapt these equipment. There is something wrong with IOMMU compatibility of phytium CPU, so we have to set IOMMU as default passthrough mode to avoid this isssue. And we can change the IOMMU mode by cmdline on other arm64 hardware. Signed-off-by: Bin Lai <robinlai@tencent.com> |
