Taxi drivers give me an MBA From http://blog.csdn.net/psyl/archive/2006/03/17/627496.aspx I was about to rush to the airport from Xujiahui, so I ended a meeting in a hurry and searched for a taxi in front of the mercury building. A mass found me and was very professional and straight forward to me. This stops, so I am deeply shocked by the story that follows, like a vivid MBA Case Study. To be loyal to the original intention of the taxi driver, I trie

Master Wang's fare is 1500 yuan, his "set the destination" to receive a single fare of 300, the actual group reference fare is 1500-300 = 1200 yuan, did not reach the "generation guru" group standard. Rookie group check-in reward to do two a week to join rookie group. Rookie group in the first week can be 10 yuan to sign in to encourage. This week, the r

An MBA for taxi drivers One day, I rushed to the airport from Xujiahui and searched for a taxi in front of the mercury building. A "public" found me and ended up in front of me very professionally and directly. This pause gave me a story that shocked me deeply, like a vivid MBA Case Study."Where to go ...... Okay, airport. I like to do the business of the Miluo building in Xujiahui. Here I only do two places: the Miluo building and the Junyao building

Linux is a variant of the UNIX operating system, and the principle and idea of writing a driver in Linux is similar to that of other Unix systems, but it is very different for drivers in DOS or window environments. Design the driver in the Linux environment, the thought is concise, the operation is convenient, the function is also very formidable, but the support function is few, can only depend on the function in the kernel, some commonly used operat

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

Introduction plan for linux Device Drivers-general Linux technology-Linux programming and kernel information. For details, see the following section. Ldd2, that is, linux device driver 2nd. This book helps you understand the implementation of most hardware work through the Linux OpenSource OS. It is suitable for C programmer which is not very clear about the underlying hardware mechanism and implementation. Unfortunately, I have read only the chapter

ZZ: http://www.cnblogs.com/lzjsky/archive/2010/11/19/1881911.html In different scenarios, many driver writers need to share the memory between the driver and the user program. The two easiest technologies are: 1. The application sends IOCTL to the driver and provides a pointer to the memory. Then the driver and application can share the memory. (Application allocates shared memory)2. The driver allocates memory pages, maps these memory pages to the address space of the specified user mode proces

Introduction: from 2.4 to 2.6, the Linux kernel has greatly changed in terms of the module mechanism, device model, and some core APIs that can be loaded, device driver developers are faced with porting drivers from 2.4 to 2.6 kernels, or enabling drivers to support both 2.4 and 2.6 kernels... news nbsp Introduction: from 2.4 to 2.6, the Linux kernel has greatly changed in terms of the module mechanism, de

external representation in the Code, the Code does not need to be changed even if the internal data type changes again in the future. Common macros are: The official registry cannot statically allocate these additional available device numbers, which can only be used when handling special requirements for device numbers. In fact, for assigning device numbers and creating device files, it is more likely to process device files in a highly dynamic manner. 3.2 dynamically allocat

Document directory A quick tour of the hardware The various modules and their interrelations How URBS keep it all together Input Handling Even though UNIX traditionally considers a device as either a "char device" or a "Block device" (as outlined by the 'C' or 'B' in their/DevEntry points), new classes of device are being introduced as technology advances. One of such classes is that of ''usb devices ''. An USB device is still, at its lowest levels, a ''char devic'' or a ''block devic''

of the LCD controller. 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

Under Linux, the drive device has character device driver, block device driver and network device drive three kinds, before learning the character device driver, now began to learn block device driver. First of all to compare the two device drivers why not pass, why to split into different types of drivers. Take an example to illustrate the need to introduce block device drivers:If you construct the drive i

); The filter function is called when the kernel is about to generate an event for the specified Kobject, and if 0 is returned, no event is generated Bus, device, and driver Bus A bus is a channel between a processor and one or more devices struct BUS_TYPE Char *name; struct subsystem Subsys; struct Kset drivers; struct Kse

The complex device drivers mentioned here involve PCI, USB, network devices, block devices, and so on (strictly speaking, these devices are conceptually not parallel, for example, a character device is tied to a block device, and a PCI, USB device, etc. may be part of a character device). Some of the more complex data structures and program structures associated with specific device types are also involved in the
