You need no special programs to read binary config space in /proc: just use od -x /proc/...
I'd prefer the following approach:
- Add a kernel call for PCI config space access.
- Add a single file in /proc, summarizing all known PCI devices (one per line) together with basic information about them (those found in struct pci_dev) in text format.
The lspci (?) utility would read the device list from /proc and extract all other information via the kernel call. Kernel hackers could simply read the /proc file itself and get the basic info directly.
Any better ideas?
