Hi
How about we update debug message like below:

Hi,
This is a warning message that describes the runtime driver alignment is not
4K.
UEFI PropertiesTable table feature expects all runtime driver alignment is
4K. When DxeCore loads Runtime driver, it will check its alignment and report
such warning message if it doesn't meet with the alignment. If you want to
enable this feature, you need to make sure all runtime driver at 4K. If you
don't enable it, you can just ignore this message.
To configure runtime driver with 4K alignment, you can modify DSC file to add
the following section.
[BuildOptions.common.EDKII.DXE_RUNTIME_DRIVER]
GCC: *_*_*_DLINK_FLAGS = -z common-page-size=0x1000
MSFT: *_*_*_DLINK_FLAGS = /ALIGN:4096
Thanks
Liming

Subject: [edk2] Section Alignment of elf binaries compiled with GCC(Linux)
When booting(a new device I'm currently working on) I get these warnings:
!!!!!!!! InsertImageRecord - Section Alignment(0x20) is not 4K !!!!!!!!
the warning is raised by "MdeModulePkg/Core/Dxe/Misc/PropertiesTable.c" and
when compiling using GCC from Linux, the SectionAlignment is set by
"BaseTools/Source/C/GenFw/Elf32Convert.c".
I checked the resulting binaries using "readpe" and indeed they have a
SectionAlignment of 0x20, while the precompiled binaries like Shell.efi have a
Alignment of 0x1000(4K).
So, is this a bug of my GCC compiler or of EDK2?
