Hey
First, please include Bugzilla link, so that we can have background.

Second, it is weird to me that you change the INF only.
I don't understand.  Is that a complete patch?

This solution does not make sense to me.

Please start a discussion with MdePkg owner at first.

Thank you

Subject: RE: [PATCH] SecurityPkg: Debug trace package integration to enable debug message capture on all targets.

Hi All,

We are developing a feature which will enable users to collect debug traces for all build targets(production & engineering builds). This feature would work even when no debug interfaces are available on systems. To support this feature we are required to extend the capability of the existing DebugLib implementation by supplementing it with a library that has the required extensions. We have done this implementation such that it can work with or without this feature enabled by encapsulating the changes within EXT_DEBUG macro. This way we are ensuring that our changes are not effecting the behavior of the DebugLib functionality in any way .Enabling this feature would require redefinition of the debug macro defined in debuglib while maintaining compatibility on builds without this feature . Since we are extending capability of DebugLib we are required to selectively define/redefine the macro definition based on the target of choice.

Please find the below flow chart.

[cid:image001.jpg@01D7F1B9.AE91E640]

@Yao, Jiewen<mailto:jiewen.yao@intel.com>  , We have some changes in Platform package of our Intel folder where we are using ExtDebug null libraries as shown below. So we have to add ExtDebuglib under library section in those inf files.

  #TPM

  SecurityPkg/Tcg/PhysicalPresencePei/PhysicalPresencePei.inf {

    <LibraryClasses>

      DebugLib|MdePkg/Library/BaseDebugLibNull/BaseDebugLibNull.inf

!if $(EXT_DBG) == TRUE

      ExtDebugLib|MdePkg/Library/BaseExtDebugLibNull/BaseExtDebugLibNull.inf

!endif

  }

Thanks,

Rency

Subject: [PATCH] SecurityPkg: Debug trace package integration to enable debug message capture on all targets.

We are introducing a new feature where we will be using a device to collect debug messages to extend capability of debug beyond current scope. We are required to extend capability of debug library by changing debug macro expression and collect debug messages for all target such as Debug, Release and Silent.
