When code running in some thread creates a new thread object, the new thread have its priority initially set equal to the P Riority of the creating thread, and is a daemon thread if and only if the creating thread is a daemon.

SummaryTwo reasons for Linux kernel success: (1) architecture design supports a large number of volunteer developers to participate in the development process; (2) each subsystem, especially those that need improvement, supports good extensibility. The two reasons that make Linux kernel can evolve.The location of the Linux kernel in the entire computer systemFig 1-Hierarchical structure of computer systemsHierarchy Principle: The dependencies between subsystems is from the top down:layers pictur

Because the data in this directory is in memory, it do

So, it can at least represent 32 different states at the same time._count: This field holds the page's usage count, which is how many times the page has been referenced. Very strange. When the technical value becomes-1, it means that the current kernel does not reference this page. So, you can use it in a new assignment, and note that this field uses

the mapping entries) for the DMA operation. Of course, the bus address is highly relevant to the architecture.Kernel logical address (Kernel logical addresses)The kernel logical address consists of the normal address space of the kernel. These addresses map some or all of the main memory addresses, and are often considered to be physical addresses. On most architectures, there is only a fixed offset between the logical address and the associated physical address. The type of logical address is

However, what is the user sees as a single application may in fact be a set of cooperating processes. To facilitate communication between processes, most operating systems support Inter Process communication (IPC) r Esources, such as pipes and sockets. IPC is used does just for communication between processes on the same system, but processes on different systems.A process is ofte

One of the keys to Linux's success is its ability to coexist harmoniously with other operating systems.5 Standard File types:1. Common documents2. Catalog files3. Symbolic Link File4.

The exact number of reservations can be calculated using the following formula:Reserved address = ((CPU core number-4) +256) *0.5MB+256MB, usually around 384MB.Memory Clerk Let's see memory clerk,memory Clerk is used to allocate memory, which is used to classify the allocate out, which can be done simply as shown
