Skip error check if HardwareInstance is 0 as this either means that
FmpVersion < 3 and not supported or,
"A zero means the FMP provider is not able to determine a
unique hardware instance number or a hardware instance number
is not needed." per UEFI specification.
As the FmpInstances are merged and HardwareInstance is not used
remove error check in this case.

Hi Jeff,
Thank you for the reminder.
I am wondering if the check should be for FmpVersion < 3 and not
FmpHardwareInstance != 0.
It is possible for an FmpInfoBuffer to have an FmpVersion >= 3 and
a HardwareInstance of 0. If more than one of these it found, then
that would be an EFI_UNSUPPORTED condition.
If FmpVersion >= 3, then the HardwareInstance must be filled in
with a unique value. 0 can be used if there is at most 1 instance,
so the duplicate check would never be triggered. If FmpVersion >= 3
and there can be more then one instance, then the HardwareInstance
must be a non-zero unique value.
Thanks,
Mike

That was my original approach when I saw this but I was seeing this occur on a device with FmpVersion == 3. The UEFI spec isn't completely clear but could be read that 0 is legal if this part isn't being used.
https://uefi.org/specs/UEFI/2.10/23_Firmware_Update_and_Reporting.html#efi-firmware-management-protocol-getimageinfo
It does state that this is Optional, and has a statement "A zero means the FMP provider is not able to determine a unique hardware instance number or a hardware instance number is not needed."
Also, our ESRT implementation just merges all instances to one anyways so it doesn't currently consume the hardware instance except for this check.
Thanks,
Jeff

It was not as we were seeing devices expose FMP via an option rom driver with Version == 3 and HardwareInstance = 0. If there are multiple of these device it would hit the error in the EsrtCode. The patch included does resolve the issues we were seeing.

This is unclear in my opinion. The spec does have
This number must be unique within the namespace of the ImageTypeId GUID and ImageIndex. And
For implementations that will never have more than one instance a zero can be used.
But it also states the parameter is optional and states that zero can be used when if it is not able to determine a unique hardware instance number or a hardware instance number is not needed.
I could see reasonable arguments on both sides.

Hi Jeff,
I have been studying the code for side effects from Version >= 3 and HardwareInstance = 0.
I think the only side effect with your patch is extra entries in HardwareIntances with the
same GUID value and HardwareInstance value of 0.
IN OUT GUID_HARDWAREINSTANCE_PAIR *HardwareInstances,
IN OUT UINT32 *NumberOfDescriptors,
This table is only used to look for duplicate GUID/HardwareInstance pairs and is not used
anywhere else and is freed after ESRT entries are determined. The same number of ESRT entries
are be created even if these extra HardwareInstances entries are present.
I have also not seen any comments or concerns from anyone else on this topic.
