available space linux

a.introduction (32-bit system) Linux simplifies the fragmentation mechanism so that virtual addresses (logical addresses) and linear addresses are always consistent, so the virtual address space for Linux is also 0~4g (2^32). The Linux kernel

The name "Linux" I think we will not be unfamiliar now, this more than a year with the domestic media of the competing propaganda and reports, Linux has become a hot topic. I would like to talk about these aspects of the history and development of

Linux/Unixshell scripts monitor disk space available Linux shell scripts that monitor disk free space, which are essential for system administrators or DBAs. The following is a sample shell script for monitoring disk space for your reference. 1.

Linux Space Division & MMU, linux DivisionLinux Kernel Address Space DivisionGenerally, 32-bit Linux kernel address space is divided into 0 ~ 3G is the user space, 3 ~ 4G is the kernel space. Note that the 32-bit kernel address space is divided, and

In this paper, we introduce 32-bit systems as an example of kernel space (kernel spaces) and user space.kernel space and user spaceFor a 32-bit operating system, its addressing space (virtual address space, or called linear address space) is 4G (2

http://blog.csdn.net/wuxinke_blog/article/details/8769131Is there a series of questions that are troubling you: what is the scope of the address space in which the user program compiles the connection? What is the scope of the kernel

In a multitasking operating system, each process runs in its own memory sandbox. This sandbox is the virtual address space, which is a 4GB memory address block in 32-bit mode. In a Linux system, the kernel process and user processes account for 1:3

Linux operating systems and drivers run in kernel space, applications run in user space, both cannot simply use pointers to pass data, because the virtual memory mechanism used by Linux, user-space data may be swapped out, and when kernel space uses
