Re: [edk2-buildtools] VfrCompile OrderedList

[Dong, E. <eri...@in...>]

Aaron,

As you have pointed, we can't use vfrStatementDefault to set the default value for the OrderedList statement, OrderedList can get default value through below method:

1.       Through the EFI_BROWSER_ACTION_DEFAULT_STANDARD/EFI_BROWSER_ACTION_DEFAULT_MANUFACTURING callback.

2.       Through the AltCfg String returned in the ExtractConfig function.

3.       Through the order of the options nest in orderedlist statement.
The priority from high to low, if driver get the default value from the high one, it will not try to get the default value again. Detail sample you can see the DriverSampleDxe driver in MdeModulePkg/Universal/DriverSampleDxe.

Thanks,
Eric

Subject: [edk2-buildtools] VfrCompile OrderedList

I was hoping to receive some clarification about the VfrCompile's support of defaults for the OrderedList vfr statement.  OrderedLists support the vfrStatementDefault grammer, but the vfrStatementDefault, through the vfrConstantValueField, only seems to support a Number/True/False/Time/Date/STRING_TOKEN. I don't see any support for a buffer type (EFI_IFR_TYPE_BUFFER), that would be required for supporting the ordering of values in the OrderedList statement.  Is there another way to set a default ordering for the OrderedList statements?

Thanks,
Aaron
