scratch register will tell you which interrupt was generated by the drawing command.The fence interrupt handler function is radeon_fence_poll_locked. First read the fence number, know that the fence operation caused the interruption, when the resulting interrupt fence number is the last number, you need to assign the last fence number to the current number, while updating the fence timer. If the interrupt is not the last fence number, the timer needs to be judged and then the fence interrupt qu

Radeon_ring_commit Update the GPU-side write pointer to release the ring buffer lock Need to mention is the scratch register, scratch Register is the GPU reserved for the software to use the Register, r300 the previous video card only 5 scratch registers, the future graphics card has 7 registers, the GPU itself does not rely on these registers to configure it, the

Earlier graphics cards were only used for display, and then 2D acceleration components were added to the graphics card, which were used for the operation of the screen, draw points, draw lines, and so on. With the need of game, three-dimensional simulation and scientific computing visualization, the demand for 3D is gradually increasing, the early drawing work is done by the CPU, to achieve realism and real

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

The Mesa source package contains a large number of OpenGL sample programs, including sample code in OpenGL Red Book, code to invoke glut or GLX interfaces, code to invoke EGL, and so on.Figure 1Figure 1 shows the process of a 3D application running, the OpenGL drawing program commands are translated into the command buffer by the MESA driver of the user space, and other such as vertex information/texture information/index information is put into the corresponding buffer, Mesa dr

1 Low-level coloring language TgsiThe OpenGL program uses the GLSL language to program the programmable graphics processor, the GLSL language (the following high-level coloring language refers to GLSL) is a high-level language of syntax similar to C, in the GLSL specification, GLSL language is first translated into the teaching of low-level class assembly language, and then translated into a hardware-specific instruction set. The OpenGL System Managem

In the field of graphic chips, Nvidia is a successor, and its history is only half the size of ATI. At the beginning of 1993, Nvidia was founded by Jen-hsun Huang,,chris Malachowsky and Curtis Priem, but Nvidia was once the strongest in the field of graphic processing, Nvidia's Linux driver installation software kit will automatically check the various details of the computer and automatically install a variety of

downloading the driver, use the terminal to enter the folder with the driver. Enter ls to find the driver run file. Enter Sudo./amd-driver-installer-12-1-x86.x86_64.run And then start the installation. The installation process is very simple. The installation is completed in a few steps. There are no complex options for Windows. Remember to restart after the installation is complete. Some people find that their kernel may be black screen after it is

AMD's new graphics card provides Linux support from the very beginning-general Linux technology-Linux technology and application information. The following is a detailed description. AMD announced last year that it wants to strengthen the development of Linux drivers and open the graphics card specifications.

There are many methods on the Internet, but there are not many solutions for AMD graphics cards, so I want to write a tutorial on AMD graphics cards today. First, go to this URL to download some software ., Note: This website is for Ubuntu 64-bit systems. For 32-bit users, s
