There is a lot of information on the configuration space of the PCI device, the following figure is the 64-byte configuration space that the PCI device must support, the range is 0x00-0x3f.Many PCI devices only support 64 bytes of configuration space. The difference between PCI and PCIe configuration space is as follows.In addition, the pci/pci-x and PCIe devices also extend the configuration space of 0x40

, configuration mechanism #1 is the only option to access the PCI configuration space. The RW software can read the mcfg base address: Figure 1 At the same time, we can also see the value of b0d2f0's register: Figure 2 then, based on the base address f8000000 and b0d2f0, according to The PCIe cofigration space address specification, we can get the address f8010000. We can read it through Dumphys to change the physical address value: The value read in

In this paper, we mainly introduce the loading and unloading process of a typical kmdf driver with the TraceView.exe tool. The related theory mainly comes from "Win7 Device driver Program development" book. For the use of TraceView.exe, please refer to my previous blog: Click to open the link.First, start and load orderIn section 7.2 of Win7 device driver development, "enumeration and startup of devices", it is mentioned that in order to prepare the device, Kmdf invokes the driver's callback rou

: · One is a software-initiated data request (for example, by a read function call), and the other is the hardware that asynchronously passes data to the system. For data acquisition equipment, even if there is no process to read the data, but also write constantly, waiting for the process to call, so the driver should maintain a ring buffer, when the read call can always return to the user space needed data. 7. How to initiate an interrupt request to the CPU in

Many of the available NIC drivers have actually been installed during the installation of Gnu/linux, but this one:Realtek PCIe GBE Family ControllerBut not the driver.And my desktop: the HP HP Pro 3380 MT is just using this NIC. Because there is no network, and centos6.x did not pre-installed gcc,g++ compilation environment, really toss a long time.The following summarizes the installation process:installation of a CentOS system1 Create an image file

vendors, such as AMD's a85x/a75 and Intel's z87/b75 are the chipset codes. It is mainly responsible for controlling non-video card slots such as sound card, Sata device, and I/O interface. It almost determines all functions of the motherboard and is the most important chip in the motherboard. There are a lot of old materials on the Internet, such as the "chipset" entry under Baidu encyclopedia. It also says [it is a general term of "nanqiao" and "beiqiao ], in fact, the North Bridge has been i

alignment. So pay attention to byte sequence conversion. When the powercp processor reads int_ack, the host converts the read operation into a PCI bus to interrupt the response transaction. It is the configuration space of 64 bytes that the PCI device must support. The value range is 0x00-0x3f: Many PCI devices only support 64-byte configuration space. The differences between PCI and PCIe configuration spaces are as follows: PCI/PCI-X and
