Most Linux instances are single-coreThe operating system kernel may be a micro kernel or a single kernel (which is sometimes called a macro kernel macrokernel ). These terms are defined as follows in a similar encapsulation:L microkernel (microkernel)-In the microkernel, mos

Introduction to the Linux kernel module the overall structure of the Linux kernel is already very large, and it contains many components. How can we include all the required parts in the kernel?One way is to compile all required functions into the

. Signal Processing(1) unsigned long signal;The signal received by the process. Each represents a signal of 32 types. The specified location is valid.(2) unsigned long blocked;The bitmask that the process can accept. The position indicates blocking, And the reset indicates not blocking.(3) struct signal_struct * SIG;Because both signal and blocked are 32-bit variables, Linux can only accept up to 32 signals. For each signal, each process can select a

One: The origins of LinuxLinux is an open-source computer operating system kernel. It is a Unix-like operating system written in C and POSIX compliant, and Linux was originally developed by Finnish hacker Linus Torvalds to try to provide free and free Unix-like operating systems on the Intel x86 architecture. The program began in 1991 with the help of some minix hackers in the early stages of the program, a
