call command here, C All allows for nesting of TSS process transitions, and jmp does not allow nesting. (1) processor uses TSS selector (0X2B) to find the 5th descriptor (2) in the GDT index to check if the processor type found is a TSS descriptor, If not, #GP exception will be generated. Whether it is available TSS, if the target TSS descriptor is busy, it will also produce #GP abnormalities. (3) processor for another check: permission checks, CPL

Each item is a dedicated DLL.· Device Driver (. drv) FileProgramming;When using dll, pay attention to three files:(1). h header file, which contains a. h file indicating the output class or symbol prototype or data
runtime if the corresponding module is installed ). Because modules are independent from each other, the program loading speed is faster, and the module is loaded only when the corresponding functions are requested.
In addition, it is easier to apply updates to each module without affecting other parts of the program. For example, you may have a salary calculation program, and the tax rate is changed every year. After these changes are isolated into the DLL, you can apply updates without re-gen

However, this is not surprising. During the linux Virtual Machine setup process, we can see that four IDE devices cannot be supported at the same time. Once again, when you copy a file in the primary operating system (Linux) virtual and to the client operating system (Win98) partition, you cannot instantly refresh t

"simulated interrupt return" approach.Let's take a look at what happens when CPU processing breaks:The upper part of the coloring of the "original SS, the original ESP, the original flags, original CS, the original EIP", refers to the interrupted program SS, ESP, flags, CS, EIP, these registers into the stack and out of the stack (by the iret instruction completed) are automatically completed by the CPU, And all the other registers are handled by the programmer himself. As a reminder, CS and EI
interrupt occurs every once in a while, this time period we call a tick. Assuming a tick occurs, the system has a clock interrupt, and the clock interrupt handler is automatically called (timer_interrupt), Timer_interrupt defined in Kernel/system_call.s, as shown in:Like our last _system_call, it performs some protection work first, and then adds 1 to the value of _jiffies in the 189th Line of code (_jiffies indicates the number of ticks elapsed since the system started), The 第192-194 code then

Eclipse is an open source software development project focused on providing a fully functional, commercial-quality industrial channel for highly integrated development. I
Welcome to the C language world! C language is a powerful and specialized programming language, which is popular among amateur and professional programmers. Let us know and know it before you learn it! The prototype of the C language is a language (ALGOL 60 language).In 1963, Cambridge University ALGOL 60 languages into CPL (Combined programming Language) language.In 1967, Matin Richards of the University of Cambridge simplified the

simplifications made to privilege checking allow SYSCALL and Sysret to complete in far fewer processor clock cycles th A call and RET.
This paragraph can only be understood, can not be explained, haha. Basically, the operating system uses special processing in the CPU to set up and maintain the segments that will be used.Sysret directives can only be used in cpl=0 programs, cpl>0 applications are not avail
what is. DLL file.
A DLL is a library that contains code and data that can be used by multiple programs at the same time. For example, in the Windows operating system, the COMDLG32 DLL performs common functions related to dialog boxes. Therefore, each program can use the functionality contained in the DLL to implement the Open dialog box. This helps facilitate code reuse and efficient use of memory.
By using DLLs, programs can be modular and consist of relatively independent components. For e

Control C # is a new development language developed by Microsoft, and it is an emerging development tool based on the Microsoft. NET Framework platform.
Because it was introduced by Microsoft, its compatibility and interoperability with all of Microsoft's products was beyond the programming language developed by other companies. The relationship between the Windows operating system developed by Microsoft and C # is also very close. This enables C # seamless operation of Windows.
