The images not from FV are treated as 3rd party images. They will
be deferred to dispatch when they are dispatched before EndOfDxe
event.
It's a new feature in the BS.LoadImage() path which can disallow
executing 3rd party images before EndOfDxe and re-execute them
after EndOfDxe (through EfiBootManagerDispatchDeferredImages
introduced in next commit).

UID (User Identification) is a standalone feature and I don't think it is
actively used by the industry. I don't want to combine this feature with
the UID.

Yes It has to be called from PlatformBDS because it should be called after
platform signals the EndOfDxe event (and Install ReadyToLock protocol).

Sounds like a good idea. I will do it after this patches are committed.

Yes I agree calling this more than once is unnecessary. I will change the patch
to call it only once.

I see your needs now. So how about I only register this callback in DEBUG
build, surrounding the code with DEBUG_CODE() macro?
Make this as an API requires platform manually register this callback, which
I think is not very convenient to platform.

The 3rd party image should be loaded after EndOfDxe event signal and
DxeSmmReadyToLock protocol installation. But non-SMM platform doesn't
published DxeSmmReadyToLock protocol.
So the SecurityStubDxe can only depend on EndOfDxe event.
This patch enhances the SecurityStubDxe to listen on
DxeSmmReadyToLock protocol installation and if any 3rd party image
is loaded before DxeSmmReadyToLock, it reports failure.

Can you please add a note to the commit message that, if the platform
installs EfiDxeSmmReadyToLockProtocol, then the deferred images must not
be dispatched prior to that either, not just prior to EndOfDxe?
Simultaneously, I propose the following subject (72 chars):
OvmfPkg/PlatformBds: Dispatch deferred images after EndOfDxe/ReadyToLock
No need to repost just because of this; the commit message can be
updated before you commit the series.
With the commit message update:

I see that you added my R-b to the commit message.
9789894e3ba3dae87bfc384e97f946caeab389e0
But, you didn't update the patch like I requested. :(
Please pay more attention. Otherwise next time I'll have to ask for a
full repost, to make sure that my request is addressed.

Reviewed all BDS related patches including PlatformBds libraries. All look good to me.
Thanks for offline addressing my PlatformBds related questions.

Subject: [edk2] [PATCH v2 0/9] Defer 3rd party images loading to after EndOfDxe
The patches change the default image loading policy by deferring 3rd party images loading to after EndOfDxe and add a new BDS API to dispatch the deferred images.
Platform needs to call the new BDS API
EfiBootManagerDispatchDeferredImages after EndOfDxe to ensure that any deferred images are loaded.
v2 puts the deferred images checking in DEBUG_CODE macro, corrects a typo of function name, and puts CpuDeadLoop() after ASSERT(FALSE).
v2 includes all the platform changes.
Ruiyu Ni (9):
MdeModulePkg/SecurityStubDxe: Defer 3rd party image before EndOfDxe
MdeModulePkg/UefiBootManager: Add EfiBootManagerDispatchDeferredImages
MdeModulePkg/BdsDxe: Check deferred images before booting to OS
MdeModulePkg/SecurityStubDxe: Report failure if image is load earlier
ArmVirPkg/PlatformBds: Dispatch deferred images after EndOfDxe
OvmfPkg/PlatformBds: Dispatch deferred images after EndOfDxe
CorebootPayload/PlatformBds: Dispatch deferred images after EndOfDxe
QuarkPlatformPkg/PlatformBds: Dispatch deferred images after EndOfDxe
Nt32Pkg/PlatformBds: Dispatch deferred images after EndOfDxe
