stdole2 tlb

To understand how the Linux kernel works, you have to know a little bit about the basics of hardware. Here we introduce the functions of several registers in the core components of the Intel 80x86 Series CPU protection mode, which play a vital role in the Linux kernel runtime. As for the other types of hardware, we introduce the device drivers to specific drivers. First, let's look at the main CPU architecture: The European Union (universal registers, operators, and controllers) performs the p

flags, the X86 architecture also has a write bit to provide page write protection-when this bit is zero, the corresponding page is read-only; when this bit is "1", the corresponding page can be read and written. If the write bit of a page is zero, a thread tries to write to it, which will cause memory management exceptions. Access to the fault handling program of the Memory Manager will be detailed in the following section) you must determine whether this thread can perform write operations on

window, click Build, and select Register for COMinterop.If you do not want to share the generated dll, put it in the GAC assembly. this completes the work. click build and an ArwenAddCom. dll file. this file is the com component we need. in addition, the ArwenAddCom file is displayed. tlb, which should be normal. if you do not have this tlb file, you can use some commands to call the dll file to generate i

necessarily, small page because of addressing, transmission fast, local improvement, the total IO will be reduced, then, should use small pages. 4) However, large pages can reduce the number of page faults ...... Spacek, now you tell me whether to use large pages or small pages. 3. TLB Range TLB can improve memory access speed, if there is no TLB, then each fet

the addresses of programs and data that are compiled to run in virtual memory to the actual physical addresses where the programs are stored in physical main memory. this translation process allows programs to run with the same virtual addresses while beingHeld in different locations in physical memory. -- MMU is used as a converter. The program can run in the same virtual memory, and each program is stored in different physical memory. We begin with a review of the protection features of an MP

. Because the frame size is fixed, a single allocation is an integer multiple of one frame.A process consists of several pages, one frame for each page. Therefore, the content of the process does not have to be contiguous, and each process corresponds to a page table. The OS also holds a copy of each process page table.Frame table: Includes all frames and whether they are idle or occupied.The Start Page table is placed in the PCB register because it is fast. However, as the page table becomes la

. If a = 0 in the page table, indicates that the pages in the memory have not been accessed. The paging unit never resets this flag, but must be done by the operating system.6) Dirty D: used only for page table items. This flag is set every time you write a page box.7) Available domain AVL: three places in the domain for system software designers. Information related to page usage can be stored in this domain to help analysis determine which pages should be removed from memory.8) PWT and PCD: co

In addition, you can see in the do_fork has a CLONE_VM logo, the kernel thread and address space is not, in fact, is not, set that logo is for efficiency, read the code to know that Linux in the switching task_struct, Share VMS without switching CR3 registers (on x86, of course), and kernel threads because there is no mm_struct, so in order to use this efficient strategy, it uses a active_mm field, is essentially borrowed from

page tablePage Size: Applies only to page catalog items. Set to 1, the page catalog entry points to 2M or 4 m of memory. (Hugepage)Global flag: Applies only to page table entries to prevent common pages (global pages) from being flushed out of the TLB. (This flag is valid when the CR4 Register PGE (page global enabled) flag is placed)For 2M pages, pass kernel parameters at startuphugepages=1024For 1GB pages:DEFAULT_HUGEPAGESZ=1G hugepagesz=1g hugepag

discuss Hugepages, such as hugetlb and hugetlbfs The data structure model of the virtual memory system on the operating system. It is used to store the correspondence between virtual addresses and physical addresses. When we access the memory, we first access "page table", and then Linux accesses the real physical memory ram + swap through "page table" mapping) TLB: A Translation Lookaside Buffer (TLB)

architectures, mapping relationships are typically stored in physical memory where a page table is called.Such as:The interaction between physical memory From this diagram, you can clearly see the interaction between the CPU and the page table, the physical memory. further optimization, the introduction of TLB (translation lookaside buffer, page table register buffer) is indicated in the previous section that the page table is stored in memory.

It is generated by the metadata contained in the Assembly. The original data is mainly used to describe Assembly data such as class declaration, method, and version information (similar to the TLB file of COM ). Therefore, we can use encapsulated classes to easily call the

Lookaside Buffer (TLB) is a buffer (or cache) in a CPU that contains parts of the page table. This is a fixed size buffer being used to do virtual address translation faster.A fixed cache in the CPU contains some page table ing relationships for fast conversion from virtual addresses to physical addresses.Hugetlb:This is an entry in the TLB that points to a HugePage (a large/big page larger than regular 4

divided into 4KB-sized page frames, which requires a 48-12 = 36-bit physical address high to determine the page frame position. In order to reduce the physical memory required to store the page table, memory access can be achieved by adding two pages of the directory layer to distribute the page table. In Linux, this is achieved using a 4-layer paging approach.Figure 6 Paging in 64-bit LinuxThe process of converting a bit physical address from a 64-bit linear address (only 48 bits as an address
