long light, and in the process of transmitting the signal, the network card signal lamp will keep flashing. If we're on a network connection, found that the network sometimes do not pass the phenomenon, we should look at this time the network card signal is in what state, once found that the network card signal is also flickering, the phenomenon of transmission instability is mostly due to the NIC and computer motherboard in the PCI slot contact caus

control information in the specified format to the physical layer, when the data is received, the MAC protocol first to determine the input information and whether there is a transmission error, if there is no error, The control information is sent to the LLC layer. The layer protocol is an Ethernet Mac defined by the IEEE-802.3 Ethernet standard. The latest Mac supports both 10Mbps and 100Mbps speeds of two.The Ethernet Data Link layer actually contains the MAC (media access control) Sublayer

Article Title: Implementation of ACPIPCIHot-Plug in Linux2. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. 　　 1. Introduction to ACPI hot plugging The Advanced Configuration Power Interface (ACPI), developed jointly by INTEL, MICROSOFT, and toshba, enables software, hardware, and operating systems (OS ), the motherboard and peripheral devices manage power u

markets. The installation of PCI cards is relatively simple, as long as the kernel supports, the system correctly identifies the number of cards at startup. The installation of the ISA card is not complex. For details, refer to my previous article.Www.nyfzns.net www.520cat.comThe following figure shows the network interfaces that I have actually used:★Intel etherexpress pro pci100m★RealTek 8029/8139 PCI 10

This article only discusses the general Writing of network device drivers. The Code related to the hardware is omitted because of the different hardware specifications. Are there any mistakes or supplements? You are welcome to raise them. 1. Loading and uninstalling the driver moduleIf the network device (including wireless) is PCI compliant, first register the PCI device (pci_register_driver) with the kern

packets from The miniport driver, and then use the ndis api of miniport characteristics to send data packets to the proto. The biggest advantage of NIDs intermediate driver is that all the data packets of miniport driver must be handed over to protocol driver. Therefore, the network firewall is regarded as a perfect place. Nowadays, many network firewalls use the NDIS intermediate driver to filter and intercept data packets. The filtering rules are set to the mpsendpackets, ptreceive, and ptrec

uses and who is compatible with before looking for a Linux driver, such as 3c509, ne2000, and etherexpress. such models are usually printed on the largest fast chip on the network card. Just copy them. The most common use may be the best network adapter, or the ne2000 compatibility card. I use it as an example. Note that many cheap cards are actually ne2000 compatible. For the ne2000 card, the first thing to do is to set the NIC to jumpless mode. many NICs use the PNP mode by default, which

How to find available network adapters on Ubuntu Do you want to know what Nic you are using in Linux? In Linux, it is easy to find the network card manufacturer. Open a terminal and enter the following command: Sudo lshw-C network If the above command cannot be used in sudo, do not use sudo's privileged mode. Its output looks strange but useful. *-Network Description: Wirelessinterface Product: BCM4360 802.11 acWirelessNetworkAdapter Vendor: BroadcomCorporation Physical id: 0 Bus info

The content of ACPI is complex. Learning ACPI can at least help us understand the configuration information. This information is obtained from the configuration of the legacy PNP device, to the multi-processor, to NUMA. For example, the current Multiple Core information can only be obtained from ACPI. Many codes for Linux Startup Process the configuration information, such as Linux acpi off and IOAPIC settings. ACPI related devices. Laptop-related devices, including power buttons, batteries, ext

1. Loading and uninstalling the driver moduleIf the network device (including wireless) is PCI compliant, first register the PCI device (pci_register_driver) with the kernel ), then, the probe function pointer in the pci_driver data structure points to the detection function to initialize the PCI device and register and initialize the network device at the same t

Starting with 2.6.13-RC3, the Linux kernel provides the ability to dynamically bind and Unbind devices and device drivers in user space. Prior to this, the insmod can only be bound and reconciled through the modprobe and rmmod, and this binding and bundling is for the driver and all devices. The new feature can set the connection between the driver and the individual device.Here, we take the NVMe SSD for PCI bus as an example, first execute LSPCI disp

can be achieved to increase the volume of traffic So:250mhz x 8 = 2G, or: 100MHz x = 2G But: Obviously the width of the road is better than the number of bars, the PC is the same, generally will not use the latter formula, lower FSB will greatly affect performance. However, FSB on some AMD CPU is inaccurate, but the theory is the same, outside the forest to note that most of the current CPU frequency is locked, can not be lowered or raised. Some people say: understand, add FSB is finished,

Questions raisedThe general motherboard has two NIC interface, Linux system is generally named after boot eth0,eth1, of course, if we do not eth0 and eth1 post-processing, each boot eth0 and eth1 location will not be fixed. Therefore, when the external network card, the problem of port confusion (port name and port of the
