Hi, Samer
If it's such usage case, why you don't use the below logic?
Status = GetSectionFromAnyFv (
&AppGuid,
EFI_SECTION_PE32,
0,
&AppImageBase,
&AppImageSize
);
Status = gBS->LoadImage (
TRUE,
gImageHandle,
NULL,
AppImageBase,
AppImageSize,
&ImageHandle
);
Status = gBS->StartImage (ImageHandle, NULL, NULL);
It doesn't need construct device path at all.
Thanks
Feng

Subject: Re: [edk2] [PATCH] MdeModulePkg : Add a new DxeServicesLib
GetSectionFromAnyFvEx() function
One possible usage is to be able to load an application from a FV.
* Need to search for the EFI application in all FVs using
GetSectionFromAnyFvEx()
* Once found, the file is loaded from FV to memory (in Buffer and Size
outputs of GetSectionFromAnyFvEx()
* We then need to load and start the image using gBS->LoadImage() and
gBS->StartImage()
* Load image has a DevicePath input parameter of where the image is
loaded from
The original GetSectionFromAnyFv() did not return the device path and was not
suitable for this use case.
Thanks,

Hi, Samer
As your proposed patch involves interface change, we need review it carefully
and the response may be slow.
Could you let me know at which case/usage model you need to get this FV file's
device path?
Thanks

Subject: [PATCH] MdeModulePkg : Add a new DxeServicesLib
GetSectionFromAnyFvEx() function
Dear MdeModulePkg maintainers,
Please see attached patch
Add a new DxeServicesLib function GetSectionFromAnyFvEx() to search all
firmware volumes for
A specified FFS file, and return the first matching FFS section. The function
is identical to
GetSectionFromAnyFv(), but it also returns a pointer to the FV file device path.
