大家好， 我最近在尝试在飞腾d2000（arm64）上运行 鸿蒙OS。目前鸿蒙OS的驱动（hi_osal.ko, hi3516cv500_hdmi.ko, hifb.ko等, hdf.patch, hi3516dv300.patch）是否支持arm64? Docker 编译rootfs： root@653b7eb4d81d:/home/openharmony# ./build.sh --product-name Hi3516DV300 编译 鸿蒙 rootfs时候，默认会编译 linux-5.10-stable最新的版本（当前为5.10.57）。编译时候使用ARCH=arm. 但是飞腾的ARCH为arm64. 所以在飞腾(ft-d2000 4核）上运行鸿蒙系统时， rootfs 里 vendor目录下得.ko模块无法插入到arm64的内核当中。 amos@osv:~/linux-5.10.57$ file arch/arm/boot/compressed/vmlinux arch/arm/boot/compressed/vmlinux: ELF 32-bit LSB executable, ARM, EABI5 version 1
