之后再Show Applications那里打开该软件: 首先在unallocated那里new一个新的区域,然后将其挂载(format to)到/dev/sda目录下,然后再挂载到/dev/sda5目录下,可以通过左右拉顶上那个进度条来控制,具体你们去试试就知道了。。。 扩展完之后,我又直接进到qemu那个文件夹下安装编译依然出错,草。。。 我的解决方法是把...
而操着系统运行的模式是S-Mode,所以RISCV也可以选择将异常重新导向到S-Mode,也支持异常委托机制(Machine Interrupt Delegaintion)将异常直接通过S-Mode进行处理,这样可以大大的增加操作系统的灵活性。 一般来说M-Mode是必须实现的,S-Mode也一般会有,而U-Mode是选择性扩展的。目前的RISCV芯片中例如蜂鸟的E203与K21...

然而对于类Unix的操作系统来说,异常都是由操作系统来处理。而操着系统运行的模式是S-Mode,所以RISCV也可以选择将异常重新导向到S-Mode,也支持异常委托机制(Machine Interrupt Delegaintion)将异常直接通过S-Mode进行处理,这样可以大大的增加操作系统的灵活性。
