我们知道,在 OS(operating system)中有一个 kernel mode, user mode 的概念,其用处在于限定 instruction 的执行权限。处于 user mode 的 instruction,不可以直接执行访问 hardware 等敏感操作;而处于 kernel…
The MODEB kernel provides dynamic process management, dynamic priorities, powerful synchronization operations, support of interrupt programming, and timer functions. The experience with Modula-2 pointed out, that the use of a high level programming language helps a programmer to write simple, reliable,...
Kernel Mode Rootkits The operating system kernel represents the highest level of privilege in a modern general purpose computer. The kernel arbitrates access to protected hardware and controls how limited resources such as running time on the CPU and physical memory pages are used by processes on ...

Kernel mode Related articles A processor in a computer running Windows operates in two different modes: user mode and kernel mode. The processor switches between these modes depending on the type of code it's executing. Applications operate in user mode, while core operating system components fun...
Kernel mode - The operating system and privileged programs run in kernel mode. Kernel-mode code has permission to access any part of the system. It isn't restricted like user mode code. It can gain access to any part of any other process running in either user mode or kernel mode. Much...
The Microsoft Windows operating system allows system components and third parties to expose performance metrics in a standard way by using performance counters.For information on adding a new performance counter provider to your code, see Using Kernel Mode Performance Counters....
In hosted mode, the program runs at the pleasure of the host operating system. -c: produce only the compiled code (without any linking) -o: specify the output file name for the executable. 链接选项: -Tbss org: 用org作为bss段的起始地址。 -Tdata org:用org作为data段的起始地址。 -Ttext...
