kernel-space ioctl equivalent

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
