A quick search in the Web reveals that the number of the books that are related to Windows Device drivers can be counted with the fingers of one hand. even worse, most of the books are either too old (published before or around Windows 2000) and/or not easilyReadable. Another problem is that the Windows Driver Model (WDM) is becoming more complex as time passes, so the newer books are relatively more complex to read than the older ones.

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

existing devices will be registered, but there are also special circumstances. For example, the kernel may need to work with an external network adapter that is not on the board, or controllers that are not attached to any bus.In general, the firmware Startup Process outputs a table of all devices on the board. If this table is not available, the only way to establish the correct device using the system startup code is to compile a kernel for a specific board. This board-specific kernel is wide

In the Linux kernel, The framebuffer (POST buffer) driver is the display driver standard. framebuffer abstracts the display device as the POST buffer. After the user maps the memory to the process address space, you can directly perform read/write operations, and write operations can be immediately displayed on the screen. Related display drivers and interfaces are available in Linux kernel/Linux/Drivers/Vi
Recently read a lot of kernel programming and drive development tutorials, also refer to some of the Development Board examples. The conclusion is not as high as you can imagine. Developing a driver requires a certain understanding of the kernel, not a thorough interpretation.
The drivers referred to below are for specific devices and are made to work in dynamic loading of modules. The driver framework is layered, some
One key to developing the Microsoft Hyper-V platform is to increase the performance of virtual machines by interacting with hardware. However, many system administrators are frustrated by the performance levels directly carried by Hyper-V. In fact, these performance ultimately involves understanding the I/O stack of the Virtual Machine and how it interacts with the Hyper-V hypervisor.
The management program provides a fully integrated driver, called the synthesis driver, which includes 80% of th
