Exploring the Capabilities of ARM Linux Virtual Machines: A Complete Guide（armlinux虚拟机）
The ARM Linux Virtual Machine (ARM VM) is a powerful platform that allows developers to access the full range of ARM development tools and systems within the virtual environment. With virtual machines, developers have the ability to emulate and test an entire PC environment within a sandboxed system. This is especially beneficial for developers looking to use Linux-based, real-time operating systems (RTOS). This guide will provide an overview of the capabilities of ARM Linux Virtual Machines and discuss how to get started using them.
First, let’s start with an overview of the different types of ARM VMs available. There are two categories of ARM VMs: system level VMs and user level VMs. System level VMs are the most powerful virtualization solutions for the ARM architecture. These systems allow the user to run an entire OS, such as Windows or Linux, within their own virtual environment. On the other hand, user level VMs are simpler and are used for running multiple discs, test and development projects, or for running several programs at once.
Once the user has selected their preferred VM solution, they must install the operating system. Several varieties of Linux distributions are available, such as Ubuntu, for ARM virtual machines. Most distributions of Linux for ARM VMs are based on the upstream code and have the same capabilities as their mainstream PC counterparts. Additionally, some vendors such as ARM offer a variety of user level VMs with their own flavor of Linux. Once the OS is installed, the user is ready to explore the capabilities of their ARM VM.
The core of any Linux virtual machine is the kernel; this handles the tasks of scheduling and allocating physical resources. The kernel is capable of managing memory and providing isolation between different processes. Additionally, the kernel is responsible for providing the APIs and drivers necessary to use various hardware peripherals, such as GPIO controllers and UART ports. Through the use of a user-mode features, developers can gain access to peripheral controls such as DMA.
Beyond this, there are a variety of development tools for the ARM VM. Development tools such as the GNU Compilation Collection (GCC) are available and provide users with tools to compile, link and assemble programs, as well as creating library routines. A variety of other development tools, including text editors, debuggers and compilers are available, making the ARM VM a powerful development environment.
Finally, there are several distribution packages available for rich ARM development environments. These include distributions that provide additional libraries, drivers and proprietary development tools for the ARM architecture. These packages can be used to easily develop and run applications on an ARM VM, making the platform a viable development environment.
In conclusion, ARM Linux Virtual Machines are a powerful development platform and provide users with the ability to create sophisticated applications and systems. The combination of user-mode features and development tools allows developers to easily create applications and systems using the ARM architecture. With various packages available, developers can easily set up a full featured development environment on their ARM Linux VM.
