  • 添加gendisk抽象，表示分区
  • 自动分配sdX、vdX设备名
  • 将FAT文件系统与Block Device解耦，转而绑定到Gendisk上
  • 添加磁盘设备管理器，支持注册、查找磁盘设备、分区
  • 实现把整个磁盘作为一个Gendisk的功能
  • 实现获取virtio磁盘大小的功能
  • 把磁盘、分区注册到devfs

bbs链接：https://bbs.dragonos.org.cn/t/topic/332/3

剩余的2个任务我打算开新的PR来发。原因是：

  • 要测试“整个磁盘作为gendisk”，需要kernel先支持qemu的direct linux boot。
  • 将磁盘和分区注册到devfs，功能较为独立，代码量比较多，为了控制当前这个PR的代码量，因此写到新的PR里面。

@xiaolin2004 麻烦看看
