A system call is a method that enables a user process to interact with the kernel of the operating system. A system call is a call from user mode to kernel mode. In other words, it’s the way that a program running on a computer requests a service from the kernel. We can use syste...
对于程序员开发的在该操作系统下的新应用软件或开发应用软件的新版本而言, 标准是极其重要的。 从POSIX这样的系统呼叫(system call) , 尤其是重要的呼叫(call) 中, 我可以获得一个操作系统应该具有哪些功能的一个单子; 然后我就可以通过自己的方式在自己的系统中实现每一个功能。 通过编写出这些标准, 我的系统软...

SEPC 寄存器是 RISC-V 架构中的一个特殊寄存器,全称为 Supervisor Exception Program Counter。当发生异常时,处理器会将异常的下一条指令的地址存储到 SEPC 寄存器中,然后根据异常类型跳转到相应的异常处理程序。需要注意的是,SEPC 寄存器不仅在异常处理时使用,还可以用于一些特权指令(如 SRET 和 MRET)的返回地址保...
