[edk2-devel] [PATCH v6 1/4] PcAtChipsetPkg: PcAtChipsetPkg.dsc add UefiCpuLib LibraryClass

[edk2-devel] [PATCH v6 1/4] PcAtChipsetPkg: PcAtChipsetPkg.dsc add UefiCpuLib LibraryClass
Posted by Kirkendall, Garrett 5 years, 7 months ago 
In preparation for moving StandardSignatureIsAuthenticAMD to UefiCpuLib
in UefiCpuPkg, PcAtChipset/PcAtChipsetPkg.dsc needs LibraryClass
UefiCpuLib.
LocalApicLib|UefiCpuPkg/Library/BaseXApicLib/BaseXApicLib.inf will need
UefiCpuLib LibraryClass.  Likely most "real" platforms will be using
BaseX2XApicLib instance which already required UefiCpuLib.

Re: [edk2-devel] [PATCH v6 1/4] PcAtChipsetPkg: PcAtChipsetPkg.dsc add UefiCpuLib LibraryClass
Posted by Guomin Jiang 5 years, 7 months ago 
Hi Garrett,

Thanks for report quickly and it work and the 'Mac format issue disappear'.

But another build error occur 'error LNK2005: _InitializeFloatingPointUnits already defined in FspSecCoreT.lib(InitializeFpu.obj)'
It seem that result by ApicLib who depend UefiCpuLib now.

I want to know why you add this dependency, have any other way to do it, for example, add the dependency to the dsc file.

Best Regards
Guomin

Yes.

It was discussed on the list in advance.

[edk2-devel] UefiCpuPkg: Discuss: Move StandardSignatureIsAuthenticAMD
function to BaseUefiCpuLib

  https://edk2.groups.io/g/devel/message/61079

In addition, we have investigated all the platforms in the open source
edk2 and edk2-platforms trees that could require an update due to the
new dependency:

  https://edk2.groups.io/g/devel/message/61525

And this series is in fact addressing them all.

> have any other way to do it, for example, add the dependency to the dsc file.

Please describe how you can reproduce the link error using edk2 and
edk2-platforms content *only* (= using open source components only).

Thanks
Laszlo

Hi Laszlo,

The step to reproduce as below:
1. add below change
diff --git a/IntelFsp2Pkg/IntelFsp2Pkg.dsc b/IntelFsp2Pkg/IntelFsp2Pkg.dsc
index 26cd3da43c3f..d43cb5be6472 100644

2. build -p IntelFsp2Pkg\IntelFsp2Pkg.dsc -b DEBUG -a IA32 -t VS2019 and I can see BaseUefiCpuLib.lib(InitializeFpu.obj) : error LNK2005: _InitializeFloatingPointUnits already defined in FspSecCoreT.lib(InitializeFpu.obj)

I can't reproduce it with the original edk2 or edk2-platforms, but our project have the depend on ApicLib, so if the ApicLib depend on UefiCpuLib, it will break our project build.

Below
Thanks.

Re: [edk2-devel] [PATCH v6 1/4] PcAtChipsetPkg: PcAtChipsetPkg.dsc add UefiCpuLib LibraryClass
Posted by Dong, Eric 5 years, 7 months ago 
Hi Guomin, Laszlo & Garrett,

Because both UefiCpuLib and FspSecCoreT / FspSecCoreM both define InitializeFloatingPointUnits API. So this build issue been reported.

I have submit a patch to remove InitializeFloatingPointUnits in FspSecCoreT / FspSecCoreM, https://edk2.groups.io/g/devel/message/61757.

Please wait that patch been merged before committing this change.

Thanks,
Eric
