Re: [edk2-devel][PATCH] UefiPayloadPkg: Fix boot shell issue for universal UEFI payload
Hi Mike,
Thanks to share the details. I think you are right the "buffer" need be freed
using ReadSection().
I don't really want to read the shell file, so I would update this patch to use
ReadFile() which supports NULL for the file buffer.
Thanks,
Guo

Hi Guo,
thanks for your explanation.
I may be wrong, but there is a different logic used.
Passing pointer to NULL means request for callee allocation.
I assume EFI_FIRMWARE_VOLUME2_PROTOCOL implemented in
MdeModulePkg/Core/Dxe/FwVol.
So, Fv->ReadSection() actually is FvReadFileSection() call [1].
This function passes pointer to pointer to buffer (aka void **) into
GetSection() function.
edk2 contains only one implementation of this function in
MdeModulePkg/Core/Dxe/SectionExtraction/CoreSectionExtraction.c
And the code [2] handling Buffer variable is below:
if (*Buffer != NULL) {
//
// Caller allocated buffer. Fill to size and return required size...
//
if (*BufferSize < CopySize) {
Status = EFI_WARN_BUFFER_TOO_SMALL;
CopySize = *BufferSize;
}
} else {
//
// Callee allocated buffer. Allocate buffer and return size.
//
*Buffer = AllocatePool (CopySize);
if (*Buffer == NULL) {
Status = EFI_OUT_OF_RESOURCES;
goto GetSection_Done;
}
}
Same pattern used in FvReadFile() implementation.

Re: [edk2-devel][PATCH] UefiPayloadPkg: Fix boot shell issue for universal UEFI payload
Hi Mike,
Thanks for your comments.
The "Buffer" is initialized to NULL for ReadSection call, we don't need free
"Buffer" since there is no data really read to Buffer.
With "Buffer" set to NULL, it just test if the file exists in the FV. If it
exists, it will return success with file size.
Thanks,
Guo

From: Guo Dong
After moving BDS driver to a new FV for universal UEFI payload, the shell boot
option path is not correct since it used the BDS FV instead of DXE FV in its
device path.
This patch would find the correct FV by reading shell file.
It also removed PcdShellFile by using gUefiShellFileGuid.
