The device is usually programmed by means of a read-write device register, which is programmed on the X86 system by a dedicated IO instruction, and on other systems such as MIPS, SPARC, by mapping the device's registers to the memory address space directly using read-write memory to program the device.Radeon graphics card provides two ways to program the hardware, a "push mode" is called the direct write register, the other is called pull mode, this b

written cp_int_stat register.In the Radeon driver code, the Radeon_fence_emit function (referred to as the code in the GPU Command Pack chapter) is called after completion of filling the drawing command into the ring buffer, and the R600_fence_ring_emit function is eventually called on the R600 graphics card. The function has the following code:2327 void R600_fence_ring_emit (struct radeon_device *rdev,2328 struct radeon_fence *fence)......2347/* Emi

The memory of the video card is divided into two parts, part is the video card comes with the memory called VRAM RAM, and the other part is the system main memory is called GTT RAM (the graphics translation table and the gart behind the same meaning, refers to the Graphics Card page table, GTT Memory can be understood as the need to build a GPU page table memory). On embedded systems or integrated

The previous blogs have described some of the DRM drivers, graphics card memory management mechanisms, and interrupt mechanisms, and it should be much easier to read the AMD DRM-driven initialization process.Here is an article written by an AMD developer (put it here for the time being, and then add your own view later).Understanding GPUs from the ground upI get asked a lot on learning how to program GPUs. Bringing up evergreen kms seems type a good p

In the Linux/unix environment, the earliest graphics system is xorg graphics system, xorg graphics system through the expansion of the way to adapt to graphics and desktop graphics development needs, but with the development of hardware and software, especially the developme

IntroductionGUI graphic screen is a "graphic LCD Controller + TFT LCD Screen" LCD module, can be used as a third-party graphics library Emwin/ucgui, Microchip-gui, EGUI, Stellarisware-grlib, Microwindows, UGFX and so on graphic display device, GUI graphic screen and traditional TFT LCD screen The biggest difference is that it has 2D graphics acceleration function as well as the font and picture can be st

How does the video card driver update? How to update the graphics driver problem toss a lot of beginners. In fact, driving life a key to solve how to install the video card driver problem. How to update the graphics driver, how to update the graphics driver, how to install the Win7 graphics driver, and so on a series o

Independent video card refers to the existence of a stand-alone card, can be in the graphics interface with the motherboard on the free plug-in card. Independent graphics card has a separate video memory, does not occupy the system memory, but also technologically advanced integrated graphics, to provide better display and operational performance. The current con

Currently, the two mainstreamGraphics cardThe manufacturers are ATI and nvdia, and their graphics cards have their own unique characteristics. However, the functions and usage of the two brands of graphics cards are completely different. Nvdia video cards focus on the game picture and picture quality. ATI graphics cards focus on textures and lines. Because the NV

1. FramebufferThe framebuffer driver provides a basic display, and the framebuffer-driven hardware is a display controller and frame cache (one piece in the system main memory or graphics memory). The framebuffer driver provides the application with a/DEV/FBX device interface that the application implements to the display controller and frame cache by reading and writing to this device node.The following program shows the process of operating the Fram

Every time you install a computer, you need to install a graphics driver, but many beginners do not know how to find and install the driver, in fact, we can use to drive life to install updates, and then take a look at it! What happens if you don't update or even install a video driver? Graphics drivers if not installed, Windows system color display will be very poor and bad. Because Win7 integrates a lar
