, the native oom mechanism of Linux has been modified according to the characteristics of the embedded device, so there is a low Memory Killer.Memory management is not the focus of this article, want to know low memory killer friends can check the relevant data or view the source code, here do not do a detailed introduction. The position of low Memory killer in the source code is: @/kernel/goldfish/drivers/staging/android/lowmemorykiller.c. Here are the questions to be clarified by two points:A.

Chapter 3 3.1 The choose I/O schedule completely fair queuing mechanism in I/O scheduling mode is consistent with its literal meaning and is a completely fair scheduling form. The I/O Request generated by each process is assigned a serial number. The I/O Request queue between processes is independent and requests with the same serial number are executed each time. AlgorithmCFQ will first consider the prior

Chapter 3 Optimization of queuing system application of queueing theory the optimization of queuing system plays an important role in cluster computing. There are two types of optimization problems: the optimal design and optimal control of the system. The former is called the static optimization problem, and the purpose is to achieve the maximum benefit of the system, or the system is the most economical u

Because many websites provide users with more than recommendation-based content.For item-CF, item similarity tables must be updated frequently when items are cold-started, with high time complexity.If there is no cold start problem in the item content-based model, cold start can be properly solved. Generally, the item content can be represented by the vector space model. This model represents an item

Conflict detection is a policy that determines whether to insert, update, or delete data. The conflict is because the target data is inconsistent with the data previously inserted, updated, or deleted on the source node. Conflict resoluti

in the water. If you are standing on the shore, you can jump there, but it is more skillful to come up from the river. Maybe you will find a good start point-your profit target price, you can place a price order. You may want the river to take you where you want to go. It is best to use a stop to protect your position. Doing so may increase your profit, but it will also increase your slide loss. The best price order. There may be opportunities lost sometimes, but there are many other opportunit

Chapter 3 LAN principlesLAN technology mainly corresponds to the physical layer and data link layer of the OSI reference model, that is, the network interface layer of the TCP/IP model. The physical layer of a LAN specifies the physical and electrical properties, mechanical properties, and connection labels of devices, cables, and interfaces that provide services to the LAN. Common such standards include: F

Interrupt mechanism of PCI busConnection between interrupt signal and interrupt ControllerConnection between interrupt signal and PCI busThe PCI bridge specification does not require the bridge to pass the interrupt request of its next PCI device. In fact, most PCI bridges also do not provide interrupt pin intx# for downstream PCI buses to manage their downstream PCI devices.At the same time, the interrupt mechanism in PCI Express is using the MSI interrupt mechanism. So the interrupt mechanism

, the prototype object at this point will contain a pointer to another prototype, and a pointer to another constructor is also included in the other prototype . . If another prototype is another type of example, then the relationship is still established, so that the level of progression, constitutes an example and prototype chain. There is a basic pattern for implementing a prototype chain, roughly the following:function supertype () { This . property = true ;}SuperType.prototype.getSuperValue
