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-time effect, can only draw some simple wireframe model, in the 80 's, Stanford University

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

queue.The 2703 line involves the fence mechanism, which we'll cover in detail in the interrupt mechanism section.The same code that reads the indirect buffer mechanism is not too difficult.Indirect buffer to be able to function properly, it must be inserted into the code of the ring buffer, which is similar to inserting a "call xx" directive into the assembly code for function calls. The command added by the Radeon_ring_ib_execute function is equivalent to the call instruction used when the fun

This one test is the flagship model of the next generation of "Bristoal Ridge" processors: a12-9800. Compared to the previous generation of APU, this generation of AMD CPUs supports ddr4-2400 memory, NMVE protocol SSD, providing greater bandwidth and support for USB 3.1. From the extended functionality to catch up with Intel's mainstream processor. Let's take a look at the CPU performance of the a12-9800. Judging

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.

(ret) {fprintf (stderr, "failed to retreive buffer stride:%s\n", Strerror (-ret));Kms_bo_destroy (BO);return NULL;21}ret = Kms_bo_map (bo, virtual);if (ret) {fprintf (stderr, "failed to map buffer:%s\n", Strerror (-ret));Kms_bo_destroy (BO);+ Return NULL;27}return Bo;This code is similar to the code in the kernel, and the reader should be able to understand its meaning based on the function name of the called function. To write a complete program, you can refer to the LIBDRM source code or the

Knowledge Point Analysis: Common "double A platform" models are:G485, Y485, S415, S405, S435, Bxx-45, Gxx-45, Nxx-45 and other models Test Platform:S415 Touch, Cpu:amd a4-5000m (HD 8330); GPU:AMD Radeon 8570M Operation steps: 1, right click on the desktop, select "Configure interchangeable display card"; 2, open AMD CCC, click on "All Applications", where you can individually switch control of a single process video card settings; 3

After restructuring, acceleration, and comprehensive transformation, AMD has been reborn. A brand new future-oriented AMD will take into account the traditional PC business and emerging business markets, and face the challenges of the cloud computing era with innovative technology, unique vision and powerful execution. In August 14, the amd chief executive team,

Modular architectureBefore learning about AMD and CMD specifications, you still need to first briefly understand what is modular and modular development?Modularization refers to the systemic decomposition of a problem according to a classification of thinking when solving a complex problem or a series of Mixed Problems. Modularization is a way to process complicated systems into manageable modules with a more reasonable code structure and higher maint

use.First, since it is a modular design, the ability to act as a modular system: 1.Defines the encapsulated module.2. Define the dependencies of the new modules on other modules.3. Can support the introduction of other modules. Well, thought has, then always have something to build a modular system of norms, otherwise all kinds of module loading will only make the bureau more chaotic. Then in JavaScript there are some non-traditional module development methods of the Specification COMMONJS modu

To fix this, you can downgrade to the Xorg version, which ships with CentOS 6.3:yum --disablerepo=\* --enablerepo=C6.3\* downgrade xorg\*(also need to do: yum remove xorg-x11-drv-modesetting )Do the Before you install catalyst!UPDATE END.Here's my how

While DIY players are throwing their eyes at Intel's six-generation processor this year, AMD, a new AMD Fast Dragon II X4 870K processor, has been unveiled shortly before as Intel's rival, which is similar to AMD 860K, shielding the core graphics card, featuring multicore cost-effective, Recommended for mainstream gamers who need to be equipped with discrete grap
