I have tried getting slot number from SMBIOS table entries in EFI
configuration table from the call back of event
EFI_EVENT_GROUP_READY_TO_BOOT but still It looks like
gEfiSmbiosProtocolGuid does not get installed by the time I get call
back for ready to boot event.I have registered the event at end of
driver start. here is the call that I have used to register for ready
to boot event.
gBS->CreateEventEx (
EVT_NOTIFY_SIGNAL,
TPL_CALLBACK,
MyBootEventNotifyCallBack,
&MyContext,
&gEfiEventReadyToBootGuid,
&MyBootEvent
);
Please help me if there is an alternative method to get the PCI slot
number or if there is something wrong in the above method.
Thanks in advance.

For now I will try to create EFI_EVENT_GROUP_READY_TO_BOOT and check
whether I get SMBIOS table in it. But it will be good if we can get
this changed and we get PCI slotinfo as part of some PCI protocol
structures or having a table filled with the details for Boot services
driver.
Thanks

Samer,
The Tiano SMBIOS scheme used the overly complicated data hub
abstractions to generate table entries and only created the tables via
a ReadyToBootEvent, but the new PI 1.2 Smbios protocol scheme does not
require an event an the tables can get built in real time.
So it is probably more of an issue needing the newer PI 1.2
implementation to get the correct behavior.
The only way to work around the ReadyToBoot sequencing issue you
mention is to register you ReadyToBoot event a last as possible (for
example in your driving binding Start function). This is really a hack
as the UEFI architecture does not guarantee order of event callback,
but all the implementations I know about call back in order of
registration.
