Since the integration requires multiple changes, including adding librarie= s, 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.

I believe the ARM platforms already have the change= . At least the ArmVirt does and some of the edk2-platforms.

 

This is not news. It=1B$B!G=1B(Bs been broadcast re= peatedly for the last 3 months. And the last 6 months. And the last 15 mont= hs.

Include Leif. This change adds new library class dependency for the vari= able driver. So, it requires to update the platform DSC file. It will impac= t ARM platforms.

Still waiting on some R-bs.

 

Have a new doc that will make it into a v7, if it h= elps anyone with their review=1B$B!D=1B(B

Subject: [EXTERNAL] [edk2-devel] [PATCH v6 00/14] Add the VariableP= olicy feature

 

REF:https://nam06.sa= felinks.protection.outlook.com/?url=3Dhttps%3A%2F%2Fbugzilla.tianocore.org%= 2Fshow_bug.cgi%3Fid%3D2522&amp;data=3D02%7C01%7Cbret.barkelew%40microso= ft.com%7Cdf2ee1dbc25a4810f5ce08d817674112%7C72f988bf86f141af91ab2d7cd011db4= 7%7C1%7C0%7C637285079522114249&amp;sdata=3D1%2F3MkPm5HuXeG%2FEaQgl%2F%2= F8Tqu3UvgDs6Ich2ezXgjuY%3D&amp;reserved=3D0

The 14 patches in this series add the VariablePolicy feature to the core,<= br> 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 librarie= s,
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://nam06.safelinks.protection.outlook.com/?url=3Dhttps%3A%2F%2Fgithub= .com%2Ftianocore%2Ftianocore.github.io%2Fwiki%2FVariablePolicy-Protocol---E= nhanced-Method-for-Managing-Variables%23platform-porting&amp;data=3D02%= 7C01%7Cbret.barkelew%40microsoft.com%7Cdf2ee1dbc25a4810f5ce08d817674112%7C7= 2f988bf86f141af91ab2d7cd011db47%7C1%7C0%7C637285079522114249&amp;sdata= =3Db%2FFdg6Sy2pdxbk3C%2FgVzXvoOWOxW6Z60QXRQ%2BVxGfFs%3D&amp;reserved= =3D0

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://nam06.safelin= ks.protection.outlook.com/?url=3Dhttps%3A%2F%2Fedk2.groups.io%2Fg%2Fdevel%2= Fmessage%2F53712&amp;data=3D02%7C01%7Cbret.barkelew%40microsoft.com%7Cd= f2ee1dbc25a4810f5ce08d817674112%7C72f988bf86f141af91ab2d7cd011db47%7C1%7C0%= 7C637285079522114249&amp;sdata=3DepDJobMGos0As5T2JSwhs2PTy1IDt52oLqXkxE= PJWLg%3D&amp;reserved=3D0
(the code branches shared in that discussion are now out of date, but the<= br> whitepapers and discussion are relevant).
