0.8.8RKNPU驱动更新到0.96版本报错

wx__hIg5R5

按照网站https://wiki.t-firefly.com/zh_CN ... /linux_compile.html的步骤，在不对rknpu文件夹进行替换前，是可以正常编译出自己的镜像的，说明编译的软件环境没有问题。


按照瑞芯微官方的文档


我做了两次尝试：（1）只对firefly提供的Linux SDK的rknpu进行替换，即只替换 kernel/driver/rknpu文件


（2）将瑞芯微官方5.10.198kernel 替换 SDK下的kernel文件，也报错

请问要怎样才能成功将0.8.8的NPU驱动更新到0.96

第一种内核版本问题，将报错的函数改成vma->vm_flags |= VM_MIXEDMAP和vma->vm_flags &= ~VM_PFNMAP的形式，而不是vm_flags_set 或者vm_flags_clear

哥，太强了。我解决了。
进入rknpu目录下的rknpu_gem.c
把vm_flags_set（）和vm_flags_clear（）的函数注释掉
//vm_flags_set(vma, VM_DONTCOPY | VM_DONTEXPAND | VM_DONTDUMP | VM_IO);
//vm_flags_clear(vma, VM_PFNMAP);

vm_flags_set（）函数用这句代替：vma->vm_flags |= VM_MIXEDMAP;
vm_flags_clear（）函数用这句代替：vma->vm_flags &= ~VM_PFNMAP;
