Platform-related fields are often seen in device drivers and distributed across multiple corners of the driver. This is also an important mechanism in the 2.6 kernel, it will be helpful for analyzing drivers in the future: In the linux2.6 device model, the three entities of bus, device, and

/O register has a side effect. Therefore, you cannot perform operations on it and cannot use the CPU cache. Http://qinbh.blog.sohu.com/62733495.html Second statement: My understanding: the I/O port is associated with the actual external device, and the access to the I/O port controls the external device. The "marginal effect" refers to the control device (read or

"Summary" What is UiO? UiO is the I/O running in user space, so why put I/O in user space?1, the reason that UiO appearsFirst, the hardware device can be divided into network equipment according to function, block device, character device, or according to the CPU connected to the way divided into PCI devices, USB devic

A real Linux Device and driver usually need to be attached to a bus. This is naturally not a problem for devices that are attached to PCI, USB, IIC, and SPI. However, in an embedded system, the independent peripheral controller integrated in the SoC system and peripherals attached to the SOC memory space are not attached to this type of bus. Based on this backgro

In the device-driven model of the kernel, the three entities are concerned with the bus, device, and drive.When the system registers a device, the bus looks for the matching driver, and the bus will look for the matching device when the system is registered with each driver.

// Some experience summarized during work 1. Determine the hardware model to be installed. You can find it in/etc/sysconfig/hwconf, which lists all the hardware models and manufacturers, here, vendorid refers to the hardware manufacturer number, and DeviceID refers to the device number. Generally, both the manufacturer and the device number are four digits. 2. The lspci command can be used to view inf

Ubuntu version: Ubuntu Server 10.10In the morning of 2016-03-26, the CPU fan of a server computer was not turned on and the power was burnt out (damp reason) ...In 2016-03-28 intends to fix him, so and another colleague, the former colleague's computer, to do server, but only one of the idle, replaced the hard disk, changed the memory. Plug in the network cable, the network cable light is not bright, because the NIC is bad, to pay to buy a separate network card, but do not want to spend money to

1.1 Platform bus, equipment and drive In the Linux 2.6 device-driven model, care is being put on the bus, device, and drive of these 3 entities, and the bus binds the device and the driver. When the system registers a device, it looks for a matching

, wait queues, I/O models, memory management, and more. These points of knowledge are so important that they are the ones that really prove the programmer's understanding of Linux, and only when they are well grounded.The new version removed the "Linux device Driver Development detailed" version of the first edition, the second edition of a large number of specific specific drive types of chapters such as s

connect with the kernel, into the kernel. What do you do? Why the trouble? Remember, God is fair, in the drive this trouble point, add a variety of device registration functions, is for the convenience of the application. Makes the application look at the driver is a kind of. For example: Whether you are a i2c,spi or a simple gpio driver, it fopen/dev/xxx, it is
