Hi, I'd like to obtain a list of all pci devices from the pci driver from another driver that I'm working on. I note that in the userland tool 'pciconf', this is obtained via the ioctl "ioctl(fd, PCIOCGETCONF, &pc)". I'd like to know if there is a way of obtaining the same information but directly in kernel space, rather than user space. Is there an equivalent of ioctl that I can use in my driver to get the output from the request PCIOCGETCONF from the pci driver? Thanks in advance. Best wishes, Lee Matthews
