Module scheme 

Multi-driver VFS scheme served at /bus/.

Each successfully-initialised bus driver appears as a sub-directory:

/bus/                     -> list of registered driver names + pci/
/bus/pci/inventory        -> PCI device table
/bus/pci/count            -> number of PCI devices
/bus/pci/rescan           -> (write-only) refresh PCI cache
/bus/pci/find/<vid>/<did> -> find devices by vendor/device
/bus/pci/cfg/<b:d.f>/<off>/<w>  -> raw PCI config read
/bus/<driver>/            -> driver info (compatible, errors, …)
/bus/<driver>/status      -> driver status
/bus/<driver>/error_count -> driver error count
/bus/<driver>/reg/<hex>   -> read/write a driver register
/bus/<driver>/<child>     -> child-device info (if the driver reports any)
