Bret:
Yes. I think this patch set pass code review. If no objection, I will merge it next Monday.
Thanks

Looks like I should have everything I need on this patch set. Can I assume that someone will stage it to make it into 2011-stable?

Yes, I'm working on a more sustainable solution for the test cases and have opened this bug to track it.
3073 – Provide test cases/apps for VarPol (tianocore.org) <https://bugzilla.tianocore.org/show_bug.cgi?id=3073>
I just didn't want that to hold up the rest of the code that's already been signed off on.

Bret:
V9 version change is mainly for MdeModule Variable driver. The change is good to me. Reviewed-by: Liming Gao <gaoliming@byosoft.com.cn <mailto:gaoliming@byosoft.com.cn> >
Besides, I find V9 doesn’t include the patch 0014-MdeModulePkg-Add-a-shell-based-functional-test-for-VariablePolicy. Because this patch doesn’t pass ECC, will you plan to add it later?
Thanks

主题: Re: [edk2-devel] [PATCH v9 00/13] Add the VariablePolicy feature
To clarify:
The current solution to the MorLock EndOfDxe issue is to expressly call LockVariablePolicy() in the same locations that mEndOfDxe is set (which was the mechanism that previously locked the VariableLock interface). This solution maintains parity with the old design, which is keeping with the ethos of minimal changes and similar functionality to VariableLock. It does not introduce any new dependencies.
The only drawback to this approach is that it preserves the strict ordering that was also previously required by MorLock, which I will attempt to address in later updates.

The 14 patches in this series add the VariablePolicy feature to the core,
deprecate Edk2VarLock (while adding a compatibility layer to reduce code
churn), and integrate the VariablePolicy libraries and protocols into
Variable Services.
Since the integration requires multiple changes, including adding libraries,
a protocol, an SMI communication handler, and VariableServices integration,
the patches are broken up by individual library additions and then a final
integration. Security-sensitive changes like bypassing Authenticated
Variable enforcement are also broken out into individual patches so that
attention can be called directly to them.
Platform porting instructions are described in this wiki entry:
https://github.com/tianocore/tianocore.github.io/wiki/VariablePolicy-Protocol---Enhanced-Method-for-Managing-Variables#platform-porting
Discussion of the feature can be found in multiple places throughout
the last year on the RFC channel, staging branches, and in devel.
Most recently, this subject was discussed in this thread:
https://edk2.groups.io/g/devel/message/53712
(the code branches shared in that discussion are now out of date, but the
whitepapers and discussion are relevant).
