The general Ubuntu default contains the driver of the Intel graphics card, if not, then determine whether the graphics card is too high, such as the I7 7th generation CPU is not in Ubuntu 16.04, resulting in the screen will be very card, because the Linux 4.4 kernel does not contain Intel HD Graphics 630 driver, the workaround is only to upgrade the Linux kernel

The memory of the video card is divided into two parts, part is the video card comes with the memory called VRAM RAM, and the other part is the system main memory is called GTT RAM (the graphics translation table and the gart behind the same meaning, refers to the Graphics Card page table, GTT Memory can be understood as the need to build a GPU page table memory). On embedded systems or integrated

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

IntroductionIn the PDF we can add very rich elements to the content we want to express through C # program code, such as drawing tables, text, adding graphics, images, and so on. In this article, I'll show you how to draw a graphic in a PDF and set the operation of a graphic property.The article will be described in the following points: Draw Basic shapes (lines, ellipses, circles, rectangles, triangles) Drawing a custom graphic Draw

How to switch the win10 dual-graphics card to the independent graphics card, win10 switch to the independent graphics card Many motherboards are integrated with graphics cards to support basic display requirements. However, in pursuit of display performance, especially when gamers choose independent

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. Bringing up evergreen kms seems type a good p

written cp_int_stat register.In the Radeon driver code, the Radeon_fence_emit function (referred to as the code in the GPU Command Pack chapter) is called after completion of filling the drawing command into the ring buffer, and the R600_fence_ring_emit function is eventually called on the R600 graphics card. The function has the following code:2327 void R600_fence_ring_emit (struct radeon_device *rdev,2328 struct radeon_fence *fence)......2347/* Emi

The device is usually programmed by means of a read-write device register, which is programmed on the X86 system by a dedicated IO instruction, and on other systems such as MIPS, SPARC, by mapping the device's registers to the memory address space directly using read-write memory to program the device.Radeon graphics card provides two ways to program the hardware, a "push mode" is called the direct write register, the other is called pull mode, this b
