CONFIG_HIGHMEM4G is enabled for the 32-bit Ubuntu kernel by default, but the PAE mode is disabled. In this way, when the system configures 4 GB memory, 1 GB is reserved for the kernel virtual space. The actual ava

After the above installation, everything went smoothly.
Note: It is best to disconnect the network during installation.I encountered this problem when installing 9.04. During the installation process, the progress bar is directly located somewhere (as if you are looking for a software source), and the network cable is immediately restored.

Currently, the sound card and wireless network card cannot be driven, but the Bluetooth and optical drive cannot be installed. After a few days, it may be a bit confusing.

The display driver provided by NVIDIA for Linux has been updated from 180.27 to 180.29. NVIDIA 180.29 includes the following changes:
Added GPU support for GeForce 9300 GE and Quadro NVS 420.Added support for OpenGL 3.0 on the GeForce 8 series and later released GPUs.Fixed a vulnerability that causes the VDPAU to display a green screen when the Overlay display queue is used in an intertwined state.Fixed a vulnerability that caused a running error in V

Now we will make the application more interesting. We will use the accelerator to move the object around the screen, add the object itself through HTML, and then use the accelerator reading to determine the speed and movement direction. As a preparation, we can add a canvas for the application and put an object in it. To add this canvas, we will

After the Linux kernel is loaded into memory by bootloader, the CPU first executes functions such as Start_of_setup functions in Head.s, and then jumps to Main.c,main to first execute Detect_memory function to probe the memory;int detect_memory (void) {int err = -1;if (detect_memory_e820 () > 0) Err = 0;if (!detect_memory_e801 ()) Err = 0;if (!detect _memory_88 ()) Err = 0;return err;}The Linux kernel obtains memory-related information through detect_memory_xxx, and these functions are obtained
At the reader's request, phoronix.com recently conducted a special performance test on the Linux kernel, comparing the performance of 32-bit, 32-bit physical address extension (PAE), and 64-bit. Linus Torvalds, the father of Linux systems, once said that there is a 25% performance difference between the system kernel that enables and disables config_highmem4g (which enables 32-bit systems to support 4 GB physical memory. Here we will verify it.

surrounded by a dense woven mesh conductor and covers a protective material outside the net. There are two types of coaxial cables that are widely used. One is a 50 ohm cable for digital transmission, which is also called baseband coaxial cable due to the use of the base belt, and the other is a 75 ohm cable for analog transmission. We usually choose the 75 ohm cable because most of the camera output signal is analog signal, so the anti-interference ability is strong. When connected to the BNC
