1, first say Ubuntu (PAE) principle, the following say how to open PAE and some need to pay attention to place By increasing the number of pins from 32 to 36 on the processor to increase the processor's addressing capability to reach 2^36=64GB, Intel introduces a new paging mechanism. 64GB of RAM is divided into 2^24 page boxes, the Physical Address field of the page table entry expands from 20 bits to 24

Under XP installed virtual PC Run is the following prompts: Virtual PC cannot run in PAE mode This version of Virtual PC cannot run in PAE (Physical Address Extension) mode.

Linuxdeepin is used, and the 64-bit version is available only after the download. But I don't want to download any more. Use Pae. Sudo apt-Get install linux-generic-PAE Linux-headers-generic-PAE After a reboot the PAE kernel shoshould be booted as the default option in the grub boot menu. To confirm that

Use windbg to observe the PAE-enabled paging Mechanism I introduced the paging mechanism of the CPU in section 2.7 of software debugging, because this is the supporting content of this book. Considering the length constraints, I did not discuss how to enable Pae. After the publication of the book, many readers are very interested in this content, and some readers have encountered the situation of enabling

designed a new paging method--pae pagination. PAE Paging Three-section paging, is to split the linear address into the form of 10-10-12, and PAE paging, is to split the linear address into the 2-9-9-12 of the four-segment, that is, 3-segment index plus offset. Two of these 9 are Page Catalog table index and page table index respectively. So what's the index of 2

Abstract: Intel increases the processor's addressing capability to 2^36=64GB by increasing the number of pins from 32 to 36 on the processor, while the number of linear addresses is still 32 bits, which requires a new paging mechanism. Starting with the Pentium Pro processor, Intel introduced a PAE mechanism, and another called the page size extension mechanism (PSE) was introduced in Pentium III, but Linux was not adopted, and this article does not d

This article is followed by "ora14 install Nvidia graphics driver". After installing the Nvidia graphics driver, if your host is installed with 4 GB memory (or more than 3 GB memory) and uses a 32bits system, we need to consider installing PAE to break through the memory limit. The current memory is very cheap, and many people get 4 GB of memory on the machine. However, in actual use, the system may only display about GB of memory, and not all hosts c

After PAE is turned on, the structure of the 32-bit linear address has changed, with the following structure30-31-bit: Page directory pointer table index21-29-bit: Page Catalog index12-20-bit: Page table index0-11-bit: in-page offsetAfter PAE is turned on, the address in the table is a physical address, and the size of all table entries becomes 8Byte, in the following format:Analyzing PAE's address conversi

At the reader's request, phoronix.com recently conducted a special performance test on the Linux kernel, comparing the performance of 32-bit, 32-bit physical address extension (PAE), and 64-bit. Linus Torvalds, the father of Linux systems, once said that there is a 25% performance difference between the system kernel that enables and disables config_highmem4g (which enables 32-bit systems to support 4 GB physical memory. Here we will verify it. This

Physical address extensions (PAE) and Applications Program Memory adjustment update date: 01/21/2005 Physical address expansion (PAE) x86 and application memory Adjustment Physical address expansion (PAE) x86 and application memory adjustment called 4 GB adjustment (4gt) are complementary technologies for computers using Intel processors. The application

, which occupies 32 9 digits in a linear address. Similarly, because the page Directory items have the same structure as the page table items, the higher-level page directory tables can only contain 512 page table items. The number of digits remaining in a 32-bit linear address is: 32-bit (total number of digits)-12-bit (intra-page offset)-9 (index in the page table) -9 digits (Index in the page directory table) = 2 bits. at the same time, Linux introduces a new page table level of a page direct

PAE is the physical Address extension. Our usual addressing method is to address the page directory, page table, page offset, and the way the virtual addresses were previously addressed in 10 10 12, but the addressing mode after the start of PAE has changed to address the 32-bit virtual addresses into 2 9 9 12:The theory does not repeat, and the ordinary way of addressing is not much different, specific can
