Hi Mike and Ray,
I'm here to bug you again :). I have another patchset that
unfortunately Liming has not gotten to review in a month's
time frame with weekly pings. When I bugged you last time,
he reviewed the next day, so something must have worked out
there. Can you please help get this merged?
Liming, do you need the community to find another member
to help as a second MdeModulePkg maintainer? It's obviously
a large job and you have been less responsive the past few
months, which has slowed down getting some really
important fixes into MdeModulePkg.
Thanks,
Oliver

ImagePropertiesRecordLib is currently creating Image Records that
are not accurate. It is setting the CodeSegmentSize to be the size
of the raw data in the image file, however, when the image is
loaded into memory, the raw data size is aligned to the
section alignment. This caused the memory attributes table to
have incorrect entries for systems, like ARM64, where the section
alignment is not 4k for all modules.
In fixing this, I noticed that MemoryProtection.c is using its own
version of image record creation where this logic was actually
correct. ImagePropertiesRecordLib was created to consolidate the
logic around creating and managing image records, so this patchset
also updates MemoryProtection.c to use ImagePropertiesRecordsLib
after making a few small adjustments to ensure the same functionality
is present.
This patchset was tested on ArmVirtQemu to ensure that all image
records were the same before and after this, other than fixing
the CodeSegmentSize.
v2:
- Align VirtualSize instead of SizeOfRawData
