Discussion of PCI drivers in linux-general Linux technology-Linux programming and kernel information. The following is a detailed description. Recently, I used a LINUX driver for the PCI board. After the system is started, I can detect the board and assign the hardware resources cat/proc/pci to the Board to know the information, write your own driver. You can use pci_register_driver (& my_pci_driver) to register the device (successful). This indicates that the structure of static struct pci_driver has been created. The problem is that you cannot call the probe function, is it static struct pci_device_id pci_tbl )? Or because no "new" device is added after system initialization, how can I detect program sleep (what if it is not a hot swapping device )? Please help us solve the problem!
In fact, if you can figure out the relationship and functions between the PCI device program and the user driver in the kernel, this problem will be solved. Thank you again for your experience!
