See wiki: http://en.wikipedia.org/wiki/PCI_hole PCI Holes PCI holes are a 32-bit hardware and 32-bit operating system, which causes the computer to display less memory than the actually installed memory. This part of memory is unavailable because the device needs address space to communicate with the CPU and system software. 32-bit hardware only has 4 GB addressable address space, so in order to make the de

MSI appears in PCI2.2, and PCI 3.0 allows masks to be set for each interrupt Msi-x appears in PCI3.0, relative to MSI, each device allows more interrupts, each interrupt can be configured independently Basic functions The device throws an interrupt by writing to a specific address Compared to traditional pin-based PCI interrupts: 1.

Link to this article: Http://qikee.blogbus.com/logs/37072405.html The I/O port is the communication mode between the driver and many devices. The Linux Kernel provides an operation interface for I/O port allocation, but for PCI devices, its Configuration address space has already specified the I/O port range for it, and no additional allocation operation is required. Linux KernelProvides the following inline functions to access the I/O port:Unsigned I

The sample code provided by Zhou ligong Can PCI interface card is VC, VB and Delphi, without the example of C #. net. However, when using C # To call can APIs, these APIs are very strict in data type verification, so debugging is troublesome. After a while, I finally used C #2.0 vs.2008 to call the can API to send and receive data normally. Now the API statement is provided as follows. If you have the same requirement, you can avoid a lot of detours.P
