Subject: Adding a PCI device that doesn't exist (yet)
The PCI interface to our "special sauce" is an FPGA that we're
programming after the OS boots. The hardware doesn't have PCI hot-plug
support, which means we're forced to reboot after programming in order
to re-enumerate the bus in BIOS. Or are we?
I was thinking of replacing the default scan_bus method with one that
calls the default method for most devices and inserts the non-existent
device information into the table at the appropriate time.
Has anyone been successful at this sort of thing?
