pci express nic

Interrupt mechanism of PCI busConnection between interrupt signal and interrupt ControllerConnection between interrupt signal and PCI busThe PCI bridge specification does not require the bridge to pass the interrupt request of its next PCI device. In fact, most PCI bridges a

The registration and initialization process of the pci NIC Driver is implemented. the TCP/IP protocol stack and the pci protocol stack are implemented after soft interruptions occur.0x01 reason The purpose of this study is to follow the outline below: The three handshakes, data transmission, and four handshakes are debugged by the server client program. The setup

PCI-Express is the latest bus and interface standard. Its original name is "I/O", which was proposed by Intel, obviously, Intel stands for the next generation of I/O interface standards. Changed to "PCI-Express" only after being certified by the PCI-SIG (

From the computer ' s perspective, it's a conventional bus where read and write transactions can be achieved.The trick is and all operations are packetized. Let's assume the CPU wants to write some data to a device. It forwards the order to the PCI
