https://www.ibm.com/developerworks/cn/linux/l-kerns-usrs/#ibm-pcon first, the introduction In general, the kernel and application have different address spaces on a multitasking system that uses virtual memory technology, so data exchange between the kernel and applications and between applications and applications requires specialized mechanisms for implementation, and it is well known that Inter-process

One pageThe kernel takes the physical page as the basic unit of memory management; the Memory Management Unit (MMU) transforms the virtual address into a physicalAddresses, which are typically processed in pages. The MMU manages the tables in the system in the page size unit.32-bit system: Page size 4KB64-bit system: Page size 8KBThe kernel represents each physical page in the system with the corresponding

This "Linux kernel cultivation of the road" in excellence, when, China-pub has also been on sale, although serious literature, but in order to ensure fluency, most of the text I also are the words of the burning sentence, repeated

The module subsystem (ModuleSubsystem), the unified device model (uniieddevicemodel), and the PnP support module subsystem have undergone major changes. 2. stability is improved 1. module subsystemModule Subsystem, Unified Device Model, and PnP support Module Subsystem have undergone major changes. 2. improved stability To completely prevent the kernel from loading or exporting the kernel module in use, or

I have never thought of any good way to pass parameters to the kernel through registers until now the implementation of uboot reading. In uboot, the most common method to boot the kernel is the bootm command. The bootm command can boot the "uboot format" kernel. Let's take a moment to know what the kernel is in uboot

Transferred from: http://www.linuxidc.com/Linux/2013-12/93637.htmWhen migrating Linux to a new architecture, a number of issues that developers encounter are related to incorrect data types. Sticking with strict data types and compiling with-wall-wstrict-prototypes can avoid most bugs. -wall Show all warnings -wstrict-prototypes Rigorous detection of prototypes, if not consistent, warnings appear The data types used by the

Install kernel source code: Installing kernel source code in RedHat or centos, kernel headers install Both centos and rhel5 between des following packages: Kernel-headers: It hosts des the C header files that specify the interface between the Linux kernel and userspace libr

One page The kernel uses the physical page as the basic unit of memory management; the memory management unit (MMU) converts the virtual address to the physical Address, usually in the unit of page processing. MMU manages the tables in the system in the unit of page size. 32-bit system: page size 4 kb 64-bit system: 8 KB page size The kernel uses the corresponding data structure to represent each

I. kernel space The kernel space is mapped by the kernel. It does not change with the process and is fixed. Ii. High-end memory: The physical memory address exceeds MB, which we call high-end memory. 3. kernel space distribution chart (1) The address range of the kernel s
