You have compiled 2.6.9-rtlinux-general Linux technology-Linux programming and kernel information. The following is a detailed description. Thank you for your cooperation with hellwolf8057! Rtlinux 2.6.9 from the Internet looks like 40 MB, and many problems are encountered during the compilation process. Starting from having no idea about the kernel, many geeks and jokes have been made. At first, the

), validity (availability). However, in these key areas, due to historical reasons, a variety of real-time operating system of the closure, restricting the parallel operation of different real-time software, such as Vxworks,lynxos,rtlinux,rtai. Similar to the common embedded system, in these key areas, a high security, high stability, support for a variety of real-time system APIs for application-oriented operating system is eagerly awaited [25,26,27,

and low cost of Linux are the advantages of Real-Time Linux development. More and more research institutions and business groups are conducting research and development on real-time Linux. The most famous ones are RTLinux and timesys Linux of fsmlab. Another is the INGO's RT patch. 5. Restrictions on real-time performance of the standard Linux Kernel Standard Linux has several mechanisms that seriously affect real-time performance. 1. the kernel cann

completed in a timely manner, the operating system regardless. Hard real-time, the operating system has been responsible for the operation completed, the world's first hard real-time operating system is still in development, when it can be completed, ask God. Emphasis on a concept, not real-time, soft real-time, hard real-time three concepts, not the speed of the standard, it is a definition of the concept. Linux and RTLinux ratio, high priority task

Real-Time Linux under the ARM system-general Linux technology-Linux programming and kernel information. The following is a detailed description. Maybe in the embedded field, there are two main reasons for not selecting Linux: 1. It is not easy to get started, it is not easy to develop, the maintenance cost is high, and the workload is large .... 2. Poor real-time performance The first point is not mentioned here. Now, many people are discussing the Real-Time Linux. The project engineer

. The implementation methods include:1) directly modify the Linux kernel and increase real-time performance, for example, montavista;2) add real-time modules and dual-kernel structures on top of common linux kernels, such as RTLinux or rtai.Montavista can meet users' soft real-time requirements. RTLinux or rtai focuses on enhancing Linux's hard real-time features. The time limit of a soft real-time system i

when it comes to Internet of things operating systems, you cannot mention Linux, because Linux is probably the most widely used operating system in IoT devices today. This article and everyone to share is the current common Linux-based Internet of things operating system , come together to see it . in traditional based on the Linux kernel, it can be migrated to the embedded system by cropping. However, there are many open source organizations and commercial companies that have modified Linux

market. However, it also has a series of problems, such as expensive, copyright required, and the source code is not open. The free operating system (such as Linux) source code is open and has a price advantage, however, there is still a lack of requirements for strictly meeting embedded real-time applications.

Using Linux as a software development and operation platform for electronic devices has long been a hot topic in the field of device software, which can indeed bring many benefits to e-product manufacturing enterprises. However, Linux has always been able to provide soft real-time performance, but in many applications that require hard real-time performance, such as automotive control, industrial control, and telecom infrastructure, linux systems that only support "Soft Real-Time" capabilities c

If let me do the work of the upper software, I can do it handy, but let me do platform work (System problem solving, driver writing, software porting, etc.), really unfamiliar. So many problems are stones, no experience. Many problems are a piece of cake for experienced friends, and it is always in front of me to meet the mountain. Be laughed at as a "weak chicken" ~Recently I was doing research and development on the home gateway based on the Realtek chip rtl8196e. Realtek provides an SDK devel

1. Origin of SpinlockSpin Lock: An Access Protection lock on a shared resource, which uses a "spin" loop to wait for a mutex to be acquired.在Linux中，有多套spinlock操作接口。但是，实现机制并不相同。根据使用场景，实现机制可能是“自旋“，也可能不是”自旋”方式。这些实现机制的共通特点是：以不产生调度的方式，获取互斥锁。但是，在实时Linux(RtLinux)中，spinlock却是产生调度的。2. Spinlock usespinlock的不产生调度机制决定了用途：1、对共享数据的访问操作时间一定要短。不同系统对实时性要求不同，这个时间要求有差异，应该控制在5us以内。2、spinlock接口性能较高，适用在高频繁使用，但是冲突又少的场景。3、spinlock一般作为系统基础接口，保护共享资源。例如，mutex中含有的基础变量的保护，需要使用spi

platform (one reason thin kernel execution is known as thinness). Examples of this approach are RTLinux (now proprietary by Wind River Systems), real-time Application interface (RTAI) and Xenomai. Super Micro Kernel method Here the thin-core approach relies on the smallest kernel that contains task management, and the hyper-kernel method reduces the kernel further. In this way, it is not like a kernel but more like a hardware abstraction layer (HAL)
