--> Support for fast system calls of new CPUs in Linux 2.6Reposted from: ibmdeveloperworks China Liu ZuiLinux enthusiastsMay 2004 This article analyzes the implementation of the Intel CPU quick System Call Command sysenter/sysexit introduced in Linux 2.6. Linux drivers and kernel developers can use this mechanism in their own code to improve system performance by understanding the mechanism of fast System Call commands, it also avoids some limitations caused by the

This command is introduced in the Intel (r) architecture's Pentium (r) processor.Operation If (cr4.tsd timestampcounter;Else (* CR4 is 1 and CPL is 1, 2, or 3 *)# GP (0)FI;Indicator of impact None.Protection Mode exception # GP (0)-if the TSD flag in register CR4 is set to 1 and CPL is greater than 0.The real address mode is abnormal. # GP-if the TSD flag in register CR4 is set

-friendly services and fully meet the interests of service providers. The challenge is that the application server must handle the security of service access in an Internet open environment. Fifth, avoid, detect, and resolve business conflicts. With the proliferation of business types and quantities in the Next Generation Network, the possibility of conflicts between businesses also increases rapidly. In this context, the business conflict management function is particularly important. To separa

example, the read/write interrupt control allows registers, but the compiler does not check and analyze the online assembly language. inserting the online assembly language may cause serious errors when changing the Assembly environment or changing the value of the C variable. Change in addressing methods in assembly 2 and C interfaces: Note that in the C language, local variable creation and access are implemented through the stack, and its addressing is implemented through the stack register

It is not a picture modification.Modification Method: (this article takes XP + SP2 as an example. Other System methods are similar .)1.

To meet this requirement, you must program and modify the image of the System user, that is, the image displayed on the welcome page when logging on to XP, Vista, and win7 systems. Find and ask. There are still no unified solutions and solutions, but there are some gains, as listed below: 1. There is a registry key under XP to save this path: [HKEY_LOCAL_MACHINE/software/Microsoft/Windows/CurrentVersion/hints/Administrator]"Picturesource" = "C: // Documents and Settings // All Users // Applic

/system32" directory of the computer. It allows programs to share the code and other resources necessary to perform special tasks. Many of the applications we use today are not a complete, indivisible, monolithic executable, but consist of a number of dynamically-linked library files that are fragmented and relatively independent. This coincides with object-oriented thinking, which increases the ER reusability of code and facilitates the maintenance and extension of code. ClassificationSome of t

Do you remember. We implement the transfer of privilege level from low to high with call gate and lcall instruction. Let's say we want to move code A to code B, using a call gate G, which refers to a segment of the code B in the target selector in Call Gate G. In fact, we have to consider 4 elements: CPL, RPL, Dpl_b (DPL of Code B), Dpl_g (call Gate G DPL). In the first step, when a accesses call gate G, the rule is equivalent to accessing a data segm

Vista system directory "c:windowssystem32" folder, click "Start → Control Panel" and select "Classic View" on the left, and you will see a new "desktop" entry (with the same name as the Control Panel item in XP). When you want to use the XP-style Desktop Properties Settings window, double-click the "desktop" item. The first run will pop up the window and ask if the Control Panel program is working properly. If normal, click "This control panel works properly" in the prompt box to confirm it. S

The method is to select "Start" * "Search" * "Files or Folders" (in Windows 2000/me), or "Start" * "Search" (in Windows XP). In the first text box in the left panel of the Search Results window, enter "*.cpl", specify the relevant path in the search scope, and click the "Search Now" or "search" button.

lower than the CPL, the RPL covers the CPL. This way even if the segment of the visitor has sufficient privilege level but RPLNot enough to access high-privileged data. Prevent low privilege levels from constructing high privilege level selectors to access high privilegeLevel of data (the current RPL will be placed in the RPL of the selector). If the target code snippet has a low privilege level, it cannot

We can finally look at the code of the 14th chapter by doing so much of the groundwork.For the boot code and user program, still use the 13th chapter, for the kernel program (C14_CORE.ASM), compile a few lines of error, as long as the addition dword can be resolved.1. Why use the call gateIn the 13th chapter, in order to be able to use the kernel-provided routines, the user program is call far transferred directly to the kernel routines (non-Uniform Code snippets) with instructions. Because

There are two main types: Do not change privileges, change privileges 1. Do not change the privilege level. You can use the inter-segment or intra-segment call or JMP. Do not judge between segments.

If the code segment is inconsistent, CPL = DPL and RPL If the code segment is consistent and RPL is not judged, CPL> = DPL is required, that is, the outer ring can jum

In 1967, Matin Richards of Cambridge University simplified the CPL language and produced bcpl language. In 1970, Ken Thompson of Bell
