Zarcd,
I can understand that this patch is needed for some buggy pci devices whose
VF bar behaves strangely. Incompatible PCI protocol can only deal with normal
PCI bar. And this patch is just to enhance the error handling logic.
Can you please use below code for error handling?
+ PciIoDevice->VfPciBar[BarIndex].BarType = PciBarTypeUnknown
I understand that your change is aligned to existing error handling in the beginning
of PciIovParseVfBar().
But that logic runs before PciIoDevice->VfPciBar[BarIndex].BarType is assigned.
The key is to reset the BarType to PciBarTypeUnknown so that the resource summary
code doesn't count this bar.
Thanks,
Ray

Ray suggests a one line patch instead of google's solution.

Could you help to verify Ray's solution on that card?

Zarcd,
I can understand that this patch is needed for some buggy pci devices whose
VF bar behaves strangely. Incompatible PCI protocol can only deal with normal
PCI bar. And this patch is just to enhance the error handling logic.
Can you please use below code for error handling?
+ PciIoDevice->VfPciBar[BarIndex].BarType = PciBarTypeUnknown
I understand that your change is aligned to existing error handling in the beginning
of PciIovParseVfBar().
But that logic runs before PciIoDevice->VfPciBar[BarIndex].BarType is assigned.
The key is to reset the BarType to PciBarTypeUnknown so that the resource summary
code doesn't count this bar.
Thanks,
Ray

Zarcd,
I can understand that this patch is needed for some buggy pci devices whose
VF bar behaves strangely. Incompatible PCI protocol can only deal with normal
PCI bar. And this patch is just to enhance the error handling logic.
Can you please use below code for error handling?
+ PciIoDevice->VfPciBar[BarIndex].BarType = PciBarTypeUnknown
I understand that your change is aligned to existing error handling in the beginning
of PciIovParseVfBar().
But that logic runs before PciIoDevice->VfPciBar[BarIndex].BarType is assigned.
The key is to reset the BarType to PciBarTypeUnknown so that the resource summary
code doesn't count this bar.
Thanks,
Ray

Hello,
Could you help to follow the suggestion by Laszlo and use the 'git-send-email' command rather than attaching the patch file:
https://edk2.groups.io/g/devel/message/69828
You can keep the "Reviewed-by" tag by Ray when sending out the patch.

Hi Zarcd,
It works fine with this Ray's solution. Customer confirmed it.

BTW, to be clear for this to try.
Could you confirm if this is right update with your suggestion?
if (EFI_ERROR (Status)) {
PciIoDevice->VfPciBar[BarIndex].BarType = PciBarTypeUnknown;
return Offset + 4;
}

Hi Kim,
Ray suggests a one line patch instead of google's solution.
+ PciIoDevice->VfPciBar[BarIndex].BarType = PciBarTypeUnknown;
Could you help to verify Ray's solution on that card?

Zarcd,
I may not say very clearly. I prefer to just keep below line. Can you check whether that can work?
+ PciIoDevice->VfPciBar[BarIndex].BarType = PciBarTypeUnknown;
Thanks,
Ray

Subject: RE: [PATCH] MdeModulePkg/Bus/Pci/PciBusDxe: Handle BAR sizing fail in high 32bit of MEM64.
Zarcd,
I can understand that this patch is needed for some buggy pci devices whose
VF bar behaves strangely. Incompatible PCI protocol can only deal with normal
PCI bar. And this patch is just to enhance the error handling logic.
Can you please use below code for error handling?
+ PciIoDevice->VfPciBar[BarIndex].BarType = PciBarTypeUnknown
I understand that your change is aligned to existing error handling in the beginning
of PciIovParseVfBar().
But that logic runs before PciIoDevice->VfPciBar[BarIndex].BarType is assigned.
The key is to reset the BarType to PciBarTypeUnknown so that the resource summary
code doesn't count this bar.
Thanks,
Ray
