config PACKT_MYCDEV tristate "Our packtpub special Character driver" default m help Say Y here if you want to support the /dev/mycdev device. The /dev/mycdev device is used to access packtpub. 在同一目录的 makefile 中添加: obj-$(CONFIG_PACKT_MYCDEV) += mychardev.o 更新Makefile...
In addition, Red Hat provides comprehensive documentation and resources for developers looking to create device drivers for their specific hardware. This includes detailed guides on kernel module programming, driver debugging techniques, and best practices for writing efficient and reliable drivers. Another ...
在上一小节中知道LED驱动会采用module_platform_driver函数向Linux内核注册platform驱动,其实在Linux内核中会大量采用module_platform_driver来完成向Linux内核注册platform驱动的操作。module_platform_driver定义在include/linux/platform_device.h文件中,为一个宏,定义如下: ...
在Linux设备模型的抽象中,存在着一类称作“Platform Device”的设备,内核是这样描述它们的(Documentation/driver-model/platform.txt): Platform devices are devices that typically appear as autonomous entities in the system. This includes legacy port-based devices and host bridges to peripheral buses, and most...
What are the basic steps to write a device driver in Linux? What are the key concepts to understand when writing device drivers in Linux? Can you explain how device drivers interact with the Linux kernel? “Do you pine for the nice days of Minix-1.1, when men were men and wrote their...
kernel_init()→do_basic_setup()→driver_init()→platform_bus_init()→bus_register(&platform_bus_type),注册了一条platform总线(虚拟总线,platform_bus)。 2、添加设备阶段: 设备注册的时候 Platform_device_register()→platform_device_add()→(pdev→dev.bus = &platform_bus_type)→device_add(),就...
your driver, and choose an acceptable trade-off between the programming time required and the flexibility of the result. Though it may appear strange to say that a driver is “flexible,” we like this word because it emphasizes that the role of a device driver is providingmechanism, not...
