Critical section: it is also called a critical section, which is a code segment for accessing and operating shared data.

Compile the linux0.00 kernel (full Linux Kernel Analysis-based on the 0.12 kernel)
I have bought a fully-analyzed Linux kernel written by Zhao Ke-based on the 0.12 kernel. It seems that the principles of the first four chapters have never had the courage to practice them by
Ubuntu16.04 update the kernel-using more than 4.6 of the kernel will make the Dell computer with a card faster-and uninstall excess kernel, ubuntu16.044.6
Tips: I am a Dell a-card computer. I feel less fluent than fedora when using 16.04 desktop. Later I manually upgraded to the 4.6.2 kernel and found that I can perfor

1. view the kernel commands to be updated:
Apt-cache search linux
This command will display all available kernels
2. Run the following command to install the kernel: 2.6.39-0.
Sudo apt-get install linu

This should begin with the generation process of vmliux. Bin.
From the kernel generation process, there are three main links to the kernel:
The first step is to compile the source code of the kernel into a. o file and link it to arch/i386/kernel/head. s to generate vmlinux.
Make a brief note in case you forget.The reason we need to synchronize is that we have concurrent access to shared resources. The code snippet that we will access or manipulate the shared resource is called a "critical section", which is called a "race condition" if the two execution threads are executing simultaneously in the same critical section. Here the term execution thread refers to any code instance that is executing, such as a process executed in the
