dispatch point will appear, If a process process2 with a higher priority than the currently interrupted process Process1 in the CPU1 's running queue, the interrupted process Process1 will be swapped out of the processor, even if it is running in the kernel state at this time.If the PROCESS3 on the CPU2 also enters the kernel state through the system call and accesses the same critical section, the deadloc

1. Why should we learn the kernel? Some people want to learn the kernel, while others do not. If you want to engage in system development or driver development in the future, you must learn the kernel. I just got started with the kernel and mainly learned kernel interface fu

at Tongji University who studies computer networks. The author originally specialized in telecommunications. Although China Telecom is closely connected with computers, the author can only be considered as an amateur computer enthusiast. Therefore, we should say that the book "full note" is a description from the perspective of a computer layman.LinuxOperating system kernel. The book is relatively small. When it includes all the source code of the

, the kernel defines a set of standard APIs, the application if a set of API interface can be used to invoke the kernel through this API interface, if not satisfied, the kernel will ignore, for security reasons, Otherwise the application can simply call the kernel, it is not finished, so if you learn application progra

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 implementa

Linux kernel source code learning: Zombie processes, Linux kernel source code botnets Orphan and botnets After a normal sub-process fork parent process, the two establish a parent-child relationship. When the child process ends, it notifies the parent process, clears the memory occupied by the child process, and leave

1. Comparison of several kernel debugging tools KDB: Debugging can only be performed at the compilation code level;The advantage is that two machines are not required for debugging. GDB: it lacks some essential functions when debugging A module. It can be used to view the running status of the kernel, including disassembly of kernel functions. Kgdb: it is conven

1. Create a kernel for the embedded platform (the 6410 Development Board is used as an example here) 1. Clear the original configuration and intermediate files (1) x86: Make distclean (2) arm: Make distclean 2. Configure the kernel (1) x86: Make menuconfig (2) arm: Make menuconfig arch = arm (platform to be specified) 3. Compile the kernel (1) x86: Make bzimage (

The Linux kernel of Android is stored in the kernel subdirectory. By comparing it with the standard Linux 2.6.25 kernel, we can find that it mainly adds the following content: 1. Add the gold-fish platform based on the ARM architecture. The directories added are as follows:
