Graphics systems in "original" Linux environments and AMD R600 graphics Programming (9)--r600 graphics 3D engine and graphics pipeline

1. R600 3D EngineThe R600 core is a very important GPU core of AMD, which introduces a unified processor architecture, with registers and instruction sets that are completely different from the previous GPUs and have a big difference in their programming.Figure 1 shows the hardware logic diagram of the R600 GPU core, t

Graphics system in "original" Linux environment and AMD R600 graphics Programming (3)--AMD Graphics Introduction

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

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

To write a complete program, you can refer to the LIBDRM source code or the

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

often tied to both the S-video and a VGA port or the Analog portion of a dvi-i port). The mapping is important as you need to know what encoders be in use and what they be tied to in order to program the DI Splays properly.Radeon_hpd_init () is a macro, points to the Asics specific function to initializes the HPD (hot Plug Detect) hardware F or digital monitors. HPD allows a interrupt when a digital monitor is connected or disconnected. When this happens the driver would take appropriate action

Linux 2.6.32 obtains R600 Kernel Mode settings

The Open Source ATI R600 garphics 3D graphics card driver has been submitted to the kernel in Linux kernel 2.6.32 may be included in the next year's tree. "David Ellie has entered the future GIT tree of DRM, which is a new type of code that will delay anything to the Linux 2.6.32 kernel, once the merge window is open. Most importantly, this new digital copyright management code provides kernel mode support, R600

What about AMD FX-8370? AMD FX-8370 Evaluation

Although AMD's day-to-day task is to zen the momentum, but after all Zen the fastest also have to be the end of the year or the beginning of the IPO. In such a gap, the addition of the upgrade is the pain before the dawn. As a representative of AMD High-performance CPU--FX series, although its historical evaluation has long been conclude, but the market always has a place for the FX series. This year, AMD s

AMD specs and how to turn AMD into COMMONJS

Original: http://villadora.me/2014/05/23/amd-define-and-how-to-translate-amd-to-commonjs/There has been a lot of controversy between Commonjs and AMD, and both have evolved and converged on the project. Personally, Commonjs is more developer-oriented, and for developers, it requires a clear version and management, less code and more interference, and less configu
