PCI-X and PCIe bus specifications require that their devices must support the capabilities structure. The basic configuration space of the PCI bus contains a capabilities pointer register, which stores the head pointer of the capabilities Structure linked list. A PCIe device may contain multiple capability structures. These registers form a linked list, as shown in. Each capability structure has a unique I

Install Realtek PCIe GBE Family Controller in CentOS 6. xMany available Nic drivers have been installed in the GNU/Linux installation process, but the Realtek PCIe GBE Family Controller driver does not.My desktop: HP Pro 3380 MT uses this Nic. Since there is no network, and CentOS6.x is not pre-installed with gcc, g ++ compiling environment, it has been a long time.The following describes the installation p

I talked to users and vendors about how SSD (solid state drive) is used, I found that most people think that server SSDS must be ultra-high-performance SLC (single-layer unit) PCIe flash cards manufactured by manufacturers such as Fusion-IO, micron, Virident, or LSI. Although most people know that the mainstream SAS or SATA interface SSD is in the 2.5 inch format, they seem to think that these devices are only suitable for laptops or enthusiasts. Of c

This paper mainly through the WindRiver tool graphical view PCIe device, to understand the space structure of PCIE devices. This article mainly refers to the "PCI Express Architecture Guide" and the Netizen blog: Click to open the link.I. The space structure of PCIE equipmentPCIe devices have three separate physical address spaces: device memory space (memory), I

About PCIe non-transparent bridge cache consistencyThe PCIe non-transparent bridge provides two mechanisms for migrating data from local node to remote node, respectively, based on address mapping and embeddedDma. For remote nodes, the CPU may not be aware when it accepts data, so cache consistency needs to be ensured;On the local node, when the data is transferred to its own memory via DMA, the CPU is not

Solve the problem that Qualcomm Atheros AR8161 Gigabit Ethernet NIC fails in Linux. The NIC Of My Dell I2330R-168 integrated computer broke down after upgrading a kernel version. ifconfig eth0eth0: flags=4163 Now the arch linux is installed, and the kernel is updated to the latest version. uname -a4.4.1-2-ARCH #1 SMP PREEMPT Wed Feb 3 13:12:33 UTC However, this problem still exists. I suddenly thought that I should go to the kernel site to find the

Recently I installed the Ubuntu 11.04, the system runs stably, the interface Yong Rong, more than the death of the dead do not know how many times, but found that wireless network card can not be connected to the Internet, find wireless routers, in the home when the Internet is inconvenient, for one months, did not find a good plan. Recently finally found a solution to this: The solution to the problem is to install the Madwifi Atheros drive. But to
