---restore content starts---Linux device driversOne, the role of device-drivenThe most popular explanation for device drivers is " Drive hardware Device Actions ". Drive and the underlying hardware directly to deal with, according to the specific work of the hardware device, read and write device registers, the completion of the device polling (polling (Polling) is a CPU decision how to provide peripheral equipment services, also known as "programmed

Knowledge of Linux DriversOperating system through a variety of drivers rely on home and hardware devices, it has shielded a variety of devices for users, drive hardware is the most basic function of the operating system, and provide a unified operation. Device drivers are one of the most basic components of the operating system and are more than 60% in the Linux kernel source program, so familiarity with d

In practice, WDM drivers will strictly restrict the storage of user buffer in their dispatch routines. The kmdf driver needs to be used in the Evtioincallercontext event callback function. Another important inherent limitation is that the dr

The application operates the network device through the socket.The network device driver belongs to the data link layer, communicates with the IP/ARP protocol, and directly operates the physical layer chip (NIC Chip). The three-layer protocol sends data through DEV_QUEUE_XMIT (), receives data through NETIF_RX (),

Starting with 2.6.13-RC3, the Linux kernel provides the ability to dynamically bind and Unbind devices and device drivers in user space. Prior to this, the insmod can only be bound and reconciled through the modprobe and rmmod, and this binding and bundling is for the driver and all devices. The new feature can set the connection between the driver and the individual device.Here, we take the NVMe SSD for PCI bus as an example, first execute LSPCI disp

is that the chapter is a little bit more complicated.Although the NoOp Scheduler is really simple enough to be simpler than our drivers, the 120 lines of code in 2.6.27 have amply illustrated the problem.But obviously, no matter how simple it is, as long as it exists, we take it as a liability.Here we're not going to go over and over again. Lip demonstrates what benefits, difficulties, and how to connect with the international, without using the I/O

Allocating memoryDescribes how memory is used in device drivers;How best to utilize system memory resources.Kmalloc functionThe Kmalloc memory allocation engine is a powerful tool.#include void *kmalloc (size_t size, int flags);Parameter assignment means that flags can control the behavior of Kmalloc in a variety of ways.The flag Gfp_kernel indicates that the memory allocation is performed on behalf of the process running in kernel space, which means

So far, Microsoft's latest desktop operating system, Windows 7, has been officially released for more than a year, and the author has changed its computer's operating system for the first time since it was released. After more than a year of use, I am more and more confident of the windows this time, because of its efficiency and gorgeous. I can responsibly say that Windows 7 is definitely the most gorgeous Windows system ever, but that's not the issue we're going to focus on today. So on the ot

In the Linux authoring process, there are two files that we must understand and know. One of these is the Kconfig file, and the other is the makefile file. If you are familiar with it, then it is certainly necessary for the kernel to compile the. config file, in the. config file, we found that some modules were compiled into the kernel, and some just generated a module. In the middle, how do we let the kernel discover the modules we write, which we need to explain in kconfig. As for how to gener

From one point of view, the role of a device driver is to provide a mechanism, not a policy.When writing drivers, the program ape should pay particular attention to the following basic concept: When writing kernel code to access hardware, do not impose any specific policy on the user. Because different users have different needs, the driver should handle the problem of how to make the hardware available. And the problem of how to use hardware is left
