isa to pci

This chapter is a supplement to the previous chapter. It mainly describes how the kernel associates the driver with the device. Common Data Structures of PCI Layer Struct pci_device_id {// device identifier is used to uniquely identify a device Unsigned int vendor, device, Subvendor, subdevice, Class, class_mark; Unsigned long driver_data; }; Strcut pci_dev // PCI device, similar to the net_device structure

How to obtain the pci id of a device in Linux Sometimes, you need to use the pci ID of the device during development. For example, to bind a network card with dpdk, you need to use the pci ID of the network card. The following methods can be used to obtain the pci ID. 1. Use the lspci command. For example . 0 USB contr

Sometimes, the development needs to use the device's PCI ID, such as the use of DPDK to bind a network card, need to use the PCI ID card. Here are some ways to get the PCI ID.1. Use the LSPCI command.Such as02:00.0 USB Controller:intel Corporation 82371ab/eb/mb PIIX4 usb02:01.0 Ethernet Controller:intel Corporation 82545EM Gi Gabit Ethernet Controller (Copper) (r

Failure phenomenon: User indicates that one machine with wireless card, the consultation can remove the wireless card, the solid state drive Solution: To say mSATA and mini pci-e is not a new interface, but most of the previous integration in the system products, rarely contact. And recently with the advent of wireless and solid-state hard drives, causing concern. Mini PCI-E Interface One machine, such

Failure Phenomena: Video card setup options in BIOS [IGD] [PEG/IGD] [PEG/PCI] [pci/peg] [PCI/IGD] How to choose? 　　Solution: Each option has the following meanings: The [IGD] system First initializes the IGD (built-in graphical display). [PEG/IGD] The system first initializes the peg (PCI Express graphics card).

The primary purpose of monitoring the performance of ISA Server is to enable managers to get relevant alerts in a timely manner to view and address problems when the server is in an unusual situation. Open the ISA Management Console, expand the Monitoring Configuration node, and click the Alerts folder to list all alerts in the details pane on the right (see Figure 1). By default,

Some people recently asked me about PCI device drivers, and after communicating with them, I suggest they take a look at PCI Device driver basically includes the resource acquisition of PCI, the reading and writing of the configuration space, the processing of interrupts, and the processing of the second half of the interrupt in DPC.At the same time, you must als

See a post on Fpga4fun on PCI-E, simple and easy to understand, suitable for the introduction, specially moved overOriginal address: http://www.fpga4fun.com/PCI-Express.htmlObjective:As PCI Express becomes common place in high-end FPGAs, let's see how easy FPGA Vendors made the technology available.In particular, we look more closely at Xilinx ' s

First, IntroductionThe Linux PCI driver actually consists of two parts: the PCI driver and the device itself, and the PCI driver is usually the Linux kernel, and the device itself is the driver of the developer. There are three address spaces on the PCI device: I/O space, configuration space, memory space, the CPU can

Warning: The enterprise initialization process copies the ISA Server schema information to Active Directory. Because Active Directory does not support deletion of schema objects, the enterprise initialization process is irreversible. How to install ISA Server as a firewall To install ISA Server as a firewall, follow these steps: 1. Click Start, click Run,

Some people recently asked me about PCI device drivers, and after communicating with them, I recommend that they take a look at PCI Device driver basically includes the resource acquisition of PCI, the reading and writing of the configuration space, the processing of interrupts, and the processing of the second half of the interrupt in DPC.At the same time, must

Generally, on the X86 platform, there are two main methods to access the registers in this range: 1. Configuration mechanism 1 # or configuration Mechanism 2 # Use the in/out command for access. Note that this method is different from the general in/out command to access the pci I/O space. It introduces the address port and data port. Configuration Mechanism 2 # used only on some specific motherboard. The new design should use configuration mechanism

First, the basic concepts of the class:1, the class is actually an object, this object will be created when this class is used for the first time2. As long as you have a class object, you can create an instance object from the class object in the future3. There is an Isa pointer in the instance object that points to creating your own class object4. All object methods of the current object are saved in the class object5. When sending a message to an in
