Since it's a device driver, let's look at how the device is described in Linux. All devices with system support are stored in the/dev directory. The device can also be a device node, and if a new device is added to the system, the corresponding node must be created under/dev. A device driver can often drive se

In today's computer system, the performance of the hard drive has become the biggest bottleneck affecting the performance of the machine. In the WINDOWS7 system with high requirements for accessories, the hard disk naturally becomes the object that needs to be optimized, and by turning on the AHCI mode of the hard

Early IDE interfaces have two transport modes, one is PIO (programming I/O) mode and the other is DMA (Direct Memory Access). Although DMA mode system resources are low, they require additional drivers or settings and are therefore less acceptable. Later, in the case of higher speed requirements, t
integrates the SATA driver is a complicated task. Any small mistake may cause the driver to fail to be loaded correctly. In addition, the file names, quantities, and information files of SATA drivers attached to different boards vary, and cannot be hardcoded during integration. Only one of the three steps can be taken to succeed.
