Re: [edk2-devel] [PATCH v1 1/1] MdeModulePkg: Use SmmWaitForAllProcessor() in VariableSmm driver.
Hi As Liming's mail below, PlatformStandaloneMm.fdf, DeveloperBoxMm.fdf and PlatformStandaloneMmRpmb.fdf consume VariableStandaloneMm module. I send the patch that made VariableStandaloneMm driver use SmmWaitForAllProcessor function and depend on SmmCpuRendezvousLib. In MdeModulePkg, it will be a NullLib version. The patch_V2 using nulllib version will send later and will cc you. If any problem in it, please give me some comments.

Re: [edk2-devel] [PATCH v1 1/1] MdeModulePkg: Use SmmWaitForAllProcessor() in VariableSmm driver.
I see the configuration in MdeModulePkg\MdeModulePkg.ci.yaml. I add SmmCpuRendezvousLib.h in MdeModulePkg/Include/Library folder so that it doesn't need add UefiCpuPkg.dec in [Packages] and bypass the check. For the second point, due to the patch pass the CI test, it also pass the PlatformCI_ArmVirtPkg. I don't realize that any problem in Arm platform build. Leif and Ard Does the patch has any influence on arm platform build? Liming: If the solution is not acceptable, how about I create NULL version of SmmCpuRendezvousLib in MdeModulePkg and use it in MdeModulePkg.dsc? Is that a acceptable solution for you? > -Original Message- > From: gaoliming > Sent: Wednesday, April 13, 2022 9:30 AM > To: Li, Zhihao ; devel@edk2.groups.io; 'Michael Kubacki' > ; 'Ard Biesheuvel' > ; 'Leif Lindholm' ; 'Sean > Brogan' > Cc: Wang, Jian J ; Fu, Siyuan ; > Ni, > Ray ; Kinney, Michael D ; Yao, > Jiewen > Subject: 回复: [edk2-devel] [PATCH v1 1/1] MdeModulePkg: Use > SmmWaitForAllProcessor() in VariableSmm driver. > > Zhihao: > I remember CI has the check for the package dependency.

回复: [edk2-devel] [PATCH v1 1/1] MdeModulePkg: Use SmmWaitForAllProcessor() in VariableSmm driver.
Zhihao: I remember CI has the check for the package dependency. If this patch passes CI, seemly this checker doesn't do. You can see DependencyCheck in MdeModulePkg\MdeModulePkg.ci.yaml. And, this patch introduces new dependency in VariableStandaloneMm. It has been used in edk2 platform ARM platform. This change will break these platform build. Please notify the platform owners. Sean and Michael: This patch adds UefiCpuPkg library instance SmmCpuRendezvousLib into MdeModulePkg.dsc. But, CI can pass. Is this the expected behavior?

Re: [edk2-devel] [PATCH v1 1/1] MdeModulePkg: Use SmmWaitForAllProcessor() in VariableSmm driver.
1. Although SmmCpuRendezvousLib in UefiCpuPkg, add SmmRendezvousLib.h into
MdeModulePkg/Include/Library folder bypass the check.
2. The SmmRendezvousLib is a standalone MM library and doesn’t have any DXE
service dependency. It can be used by SMM variable module and MM variable
module.
As the patch following, it have passed the Edk2 CI test. The code can run
successfully in practice, but I'm not sure if this is acceptable in terms of
the standard.

Zhihao:
This patch breaks two things. One is to let MdeModulePkg depend on
UefiCpuPkg, another is to let VariableStandaloneMm depend on UefiCpuPkg
SmmCpuRendezvousLib. Please provide your proposal to resolve these two
dependency first.

[edk2-devel] [PATCH v1 1/1] MdeModulePkg: Use SmmWaitForAllProcessor() in VariableSmm driver.
REF： https://bugzilla.tianocore.org/show_bug.cgi?id=3854
In UefiCpuPkg, there are a new Protocol with the new service
SmmWaitForAllProcessor(), which can be used by SMI handler
to optionally wait for other APs to complete SMM rendezvous in
relaxed AP mode.
This patch use the new service to let VariableSmm driver work
normally in relaxed AP mode.
