[edk2-devel] [PATCH 00/24] CryptoPkg/openssl: update openssl submodule to v3.0

PEI has this (OvmfIa32X64Pkg build):

    7062 TpmMmioSevDecryptPei
    7830 StatusCodeHandlerPei
    7902 ReportStatusCodeRouterPei
    8470 FaultTolerantWritePei
    9734 SmmAccessPei
   11206 Tcg2ConfigPei
   11842 PeiVariable
   14730 Tcg2PlatformPei
   17274 TcgPei
   18438 S3Resume2Pei
   18682 DxeIpl
   18938 PcdPeim
   38014 CpuMpPei
   39554 PlatformPei
   45050 PeiCore
   49274 Tcg2Pei

No size change for Tcg2Pei.

The other modules are not there.  Seems they are related to firmware
updates.  We don't have that on ovmf as we can simply update the
firmware image files on the host machine ...

Is there some target I could use to test-build those modules?

Any hints where I could get them?  Given this happens on windows builds
it's probably somewhere in the microsoft standard C library?  Is that
available as open source somewhere?

Seems the idea is to have only one openssl copy in the dxe image by
calling a protocol instead of linking a lib.  Makes sense.

Is this documented somewhere?  Is there some easy way to use that as
drop-in replacement?  Or do we have to change all crypto users to call
the driver instead of linking the lib?

take care,
  Gerd
