HI,
Is there any way to find which pci driver uses what memroy regions and any way to find which driver si attached to which device file
"cat /proc/iomem". That will list the memory addresses assigned to the various PCI devices. Some kernels have PCI name support compiled in (most stock distro kernels do), but without it, you get the PCI bus location numbers, and have to do a bit of work with lspci to identify what each adapter is.
I don't understand why you need to know PCI memory address regions - they are remapped at device configuration time (unlike ISA) unless you have a seriously broken adapter card.
What do you mean "any way to find which driver is attached to which device file"? You can use "cat /proc/devices" to get the major number assigned to each block and char driver, and then do a "ls -l /dev/[device file name]" to get the major and minor numbers assigned to that device. From there, things get more driver-specific - different drivers use minor numbers in different ways.
More info about what you're actually trying to do would help.
