Understanding mirroring, container, and storage driversTo use storage drivers more effectively, you must understand how Docker creates and stores images. Next, you need to understand how the container uses these mirrors. Finally, you need a technical introduction to both the mirror and container operators.Mirroring and Layer LayersEach Docker image references a series of read-only layers that represent the difference between file systems. The hierarch

1. Preface The reason to compile the Linux kernel failed many times is to drive the wrong choice, suitable for their own native drive is not compiled into. In the face of special platform (or some neat person, I am ^_^), to compile the thin kernel, as long as the native drive, no other need. In the face of the kernel so many drivers, do not understand the hardware, we see the head big. The first time I installed Gentoo, the kernel compiled 5 times, th

Part I: The MMAP system call directly maps the device memory to the address space of the user process.Part II: Direct access to memory pages of user space across borders. Some related drivers require this capability (how user-space memory maps to the kernel method get_user_pages)Part III: Direct Memory access (DMA) I/O operations enable peripherals to have direct access to the system's memory capacity.Memory Management for LinuxAddress TypeLinux is a

Brief introduction A block device driver accesses a device primarily by transmitting a fixed-size random data Linux kernel video block devices are basic device types that differ from character devices The Linux block device driver interface allows the block device to perform its maximum effect, but its complex program is a problem that programmers must face A data block refers to fixed-size data, and the value of the size is determined by the kernel The size of

(i) Reuse of Linux codereuse = static reuse (the code that will be reused is declared in the header file of other files) + dynamic reuse (using resources from another Linux driver, such as functions, variables, macros, etc.)1. Compilation is a Linux driver composed of multiple files (static reuse)For complex Linux drivers, it is necessary to use multiple source code files to store different function code, which facilitates code classification and mana

With the rapid development of information technology, the performance of hardware is becoming more and more powerful. Driver is directly working on a variety of hardware devices software, it is through-driver, a variety of hardware equipment to normal operation, to achieve the established work effect. And if the hardware is missing the driver, then the hardware often can not achieve the original effect, can not work according to the instructions issued by the software, and even cause the compute

The Python Database API is described in PEP 249. MySQL has three prominent drivers that implement the This API: MySQLdb is a native driver it has been developed and supported for over a decade by Andy Dustman. Mysqlclient is a fork in MySQLdb which notably supports Python 3 and can be used as a drop-in replacement for MYSQLDB. At the time of this writing, this is the recommended choice for using MySQL with Django. MySQL Connector/pyt

Notifies the driver when a frame is receivedin a network environment, when a device (network card) receives a data frame, it needs to notify the driver to process it. There are several notification mechanisms:Polling :The kernel keeps checking to see if the device has something to say. (More resource-intensive, but in some cases the best method)Interruption:when a particular event occurs, the device driver indicates that the device has a hardware interrupt on behalf of the kernel, and the kernel

Now when you install Windows Server 2003 for your server, or when you install XP for a workstation that uses SATA raid, you need to load the associated driver from the floppy drive, but many machines do not have a floppy drive. For a server, you can install it using the boot CD from the server, but the first logical disk for the disk display will be partitioned when installed. In the past, most of the drivers for SCSI cards, RAID cards, SATA, or SAS

One key to developing the Microsoft Hyper-V platform is to increase the performance of virtual machines by interacting with hardware. However, many system administrators are frustrated by the performance levels directly carried by Hyper-V. In fact, these performance ultimately involves understanding the I/O stack of the Virtual Machine and how it interacts with the Hyper-V hypervisor. The management program provides a fully integrated driver, called the synthesis driver, which includes 80% of th

. Specifically: Fill in a fbinfo Structure Use reigster_framebuffer (fbinfo *) to register the fbinfo structure to the kernel For the fbinfo structure, the most important thing is its fs_ops member. You need to implement interfaces in fs_ops for specific devices. Whether to use interrupt handling Memory Access If the video card does not have its own video memory, the system memory is allocated as the video memory. The graphics card comes with a vide
