Did you find a solution to this problem?

Did you find a solution to this problem?

My delevep board is base on nanopi6_linux_defconfig. So I try to enable IOMMU support.

# vim /kernel/arch/arm64/config/nanopi6_linux_defconfig

CONFIG_ROCKCHIP_IOMMU=y

It works well.

您好我也是 nanopiT6，但是我修改支持 IOMMU 依然出现这个错误，麻烦咨询一下您的环境
