SMBusDirectory the difference between SMBus and I²c SMBus is the abbreviation for System Management Bus, which was proposed by Intel in 1995 for low-rate communication in mobile PC and desktop PC systems.　　It mainly wants to control the device on the motherboard and collect the information by means of a cheap and powerful bus (consisting of two lines).　　

SMBus is a two-wire serial bus. Its first specification was commercially available in 1996. It is mostly based on I2C bus specifications. Like I2C, SMBus does not require additional pins. It is created to add new features, but only works at kHz and is dedicated to smart battery management applications. It works in Master/Slave Mode: the master device provides a clock, provides a start bit when it initiates

After installing the Ubuntu16.10 in VMware, the ' SMBus Host Controller not enabled ' Error prompt is started and cannot be entered into the GUI.Search the Web, the solution is to enter the terminal window in the graphical interface, edit the blacklist.conf file, prohibit i2c_piix4 driver loading.But now the system has not been loaded, into the terminal window, how to deal with it?The workaround is as follows (pro-Test available):Systems running on a

Asynchronous modules define AMD and asynchronous modules amd It is called Asynchronous Module Definition, and is defined by Asynchronous components (or modules.

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

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

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

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.

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

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

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.

Javasript modularity before understanding the Amd,cmd specification, it is necessary to understand briefly what is modular and modular development? Modularity refers to the systematic decomposition of a problem in order to solve a complex problem or a series of mixed problems, according to a sort of thinking. Modularity is a way of dealing with complex systems that break down into manageable modules that are more logical and maintainable in code struc
