Why do we need matching PCI ids here instead of looking at the FDT which
will work better?
what is FDT ? any is it better to use it instead of match_id ?
This is emulating the device_driver match for the pci_driver.
No it is not, it is a device tree info which lets to skip the linux PCI
discovery part (the firmware does it anyway) but it tells nothing about
which drivers to bind.
I don't think we can combine FDT matching with pci_driver, can we?
It is a c function calling another c function, all within vfio-pci, this
is not called by the generic pci code.
