Has the reason for the PciBusDxe override been discussed with the PciBusDxe maintainer?

What feature would need to be added to PciBusDxe to accommodate the use case?

Liming :

Below email is the cover letter and this patch series has two changes. Sure next time, will add more comments in the cover letter also.

Please refer the attached email and it has information about the PCIBUS override changes. PCIBUS override is done based on the platform sighting and it can’t be generic.

Thank you

And, for the override PciBus module, can you give more detail why need to override PciBus? Is it possible to update Edk2 MdeModulePkg PciBus to meet the platform requirement?

Thanks
