the manner of programming, Must be done through the 3-type command package (see the code is like this, the R600 Register manual has many register addresses are the same, but the meaning is different, these register offsets are greater than or equal to 0x8000, is correct?? ）。The following blog will introduce the memory management mechanism, command processing, interrupt mechanism of AMD graphics card, then introduce 3D engine, which includes graphics

(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

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

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

Failure phenomenon: ThinkPad E465, E565 and other AMD platform computer Win7 system times are wrong. Reason Analysis:Because the new version of the AMD chipset no longer supports the native USB2.0 interface, and the Win7 system does not integrate USB3.0 drive, there will be an error when installing Win7.Solut
