[Xen-devel] [Query] How does Xen X86 does pci enumeration

[Xenbegn developer <xen.begn.dev@xxxxxxxxx>]

Hi,

Small beginner query. Where in Xen X86 code pci ep enumeration is done?

I believe it this should be the flow of events
a)Â from ACPI enumerate all the PCI controllers

b) On each Controller start enumerating the pci devices.

I started from _start_xen in arch/x86/setup.c but couldnt find the top level function.
Can anyone please provide pointer.

Thanks
