Installing NVIDIA 3D drivers Contributed by Maurice lawles in multimedia on 2006-02-12 02:59:20 I find myself retelling how to manually install the NVIDIA 3D drivers an awful lot. Here's a short tutorial that shocould work on any distro

unit, maps physical addresses to bus addresses. Io-MMU must be set before all I/O drivers using DMA start a data transfer. Different bus have different BUS address sizes. The isa bus address is 24-bit long. Therefore, in the 80x86 architecture, DMA transfer can be completed in 16 MB of physical memory-that is why the memory buffer used by DMA is allocated in the zone_dma memory zone (with the gfp_dma flag configured ). The original PCI standard defin

difference between the two can be seen if the application's call returns immediately!Drivers often need to provide the ability to make system calls, such as read (), write (), if the device's resources are not available, and the user wants to access the device in a blocking manner, the driver should be in the device-driven xxx_read (), Xxx_write (), and so on The process is blocked until the resource is available , and then the application's read (),

It holds the processor context snapshot before the processor enters the interrupt code The interrupt processing routine should return a value. Used to indicate whether an interrupt was actually handled. If the processing routine finds that its device does need to be processed, it should return irq_handled. Otherwise. The return value should be Irq_none Enable and disable interrupts s

A VxD handles interrupts in connection with Windows and performs I/O operations for applications that require I/O operations and does not affect the execution of other applications. Most VXD management hardware devices, there are also some VxD to manage or replace related software, such as the normal ROM BIOS. A VxD can contain device-related code that must be executed on the appropriate device, or it can rely on other

Recently, I was looking at the driver model, but the more confused I was, the more I used to come into contact with some character drivers. I have a certain understanding of the character-driven framework. Later, I wanted to create a device file in the driver. I also learned that the sysfs file system and udev file system will inevitably involve the driver model. However, we found that the driver model has no connection with the character

) (Type) (NR) In this way, the macro value of _ IO () is obtained. The usage formats of these macros are as follows:: _ IO (magic number, base ); _ Ior (magic number, base, variable type) _ Iow (magic number, base, variable type) _ IOWR (magic number, base, variable type) Magic number)Magic number range: 0 ~ 255. Generally, the English character ""~ "Z" or ""~ "Z. The device driver obtains the magic number from the passed command, and then compares it with the magic number it processes. If

I have to pay 380 yuan a day, and the fuel fee is about 210 yuan. 17 hours a day, the average fixed cost of 22 yuan per hour, handed over to the company, an average of 12.5 yuan per hour oil fee. Is this 34.5Yuan? ", I was surprised. I took a taxi for 10 years and heard a taxi driver calculate the cost for the first time. The previous drivers told me that the cost per kilometer is 0.3 yuan, and the am

Generally, the drivers of devices provide the following entry points: 1. Open entry point. Open the device to prepare for the I/O operation. When you open a special device file, the open entry point of t

Because Windows shields the underlying system operations, the system becomes safer for users, but it brings great difficulties to many hardware or system software developers, as long as the application involves underlying operations, developers have to go deep into the Windows kernel to write system-level virtual device drivers.
