My adapter configuration utility needs to instruct the user which physical
adapter needs attention ( when there may be multiple adapters in the system
). My question is : How do I determine the ( machine ) slot number of a
PCI adapter ?
In BIOS and other OS's this may be doneby examining the system's PCI
Routing Tables. I don't think I can get to those from Linux.
PCI Devices are defined by BUS, DEVICE, and FUNCTION. In Linux there
is a function ( defined in pci.h near the end of the file ) called "
PCI_SLOT( devfn ) " but from what I can see this returns what PCI calls
the device. PCI device is not the machine's slot number. This function
even uses the encoded byte which is named devfn ( I assume from PCI
device and PCI function ) , but this function treats it as slot and
function.
Any help is appreciated. Thanks in advance.
