Linux Driver Development VI (instruments for hardware knowledge that must be understood) First, prefaceIn the previous article, Lao Xie has shared a lot of knowledge about the hardware that must be learned in the development process of embedded systems. As the end of this section (oops, finally to the end), Lao Xie

There is a macro __stringify in the Linux kernel, which is defined in Include/linux/stringify.h as follows:#ifndef __linux_stringify_h #define __linux_stringify_h/* Indirect stringification. Doing levels allows the parameter to be a * macro itself. */ #define __stringify_1 (x ...) #x#define __stringify (x ...) __stringify_1 (x)#endif/ *!__linux_stringify_h */The effect is actually to convert the

PCI is a widely used bus standard, it provides many superior to other bus standards (such as EISA) new features, has become the most widely used in computer systems, and the most common bus standards. Linux kernel can better support PCI bus, this paper based on the Intel 386 architecture, discusses the development of PCI device driver under

1 DMA ConceptsDMA, by definition, refers to the direct data-to-read operation between the device and memory, memory, and external storage devices without the need for CPU involvement. 2 DMA Principle DMA transmission needs to be carried out by the DMA controller DMAC, when the DMA transfer is required, the DMA controller will make a request to occupy the bus, when the CPU responds to the DMA request, temporarily abandon the control of the bus, when the DMA transfer is over, Dmac will i/ The O in
