@Gao, Liming

 

In fact, I also want to move it edk2/MdeModulePkg/Include/UniversalPayload at master · tianocore/edk2 · GitHub to MdePkg step by step, but it another, for the mail thread we can focus on TraceHub Hob move to MdePkg responsibility.

 

As you know, Intel silicon may also provide MMIO UART

https://github.com/tianocore/edk2/blob/master/MdeModulePkg/Include/UniversalPayload/SerialPortInfo.h This HOB need to provide by silicon code in the future will be made sense.

 

We can review patch one by one and consider whether it’s make sense or not.

 

In past, we discuss it with Mike, TraceHub can support UPL enable case and UPL disable case.

So recommend us to put it into common area. It’s background.

Past PR: MdeModulePkg: Add Trace Hub Debug Library by hsuc1x · Pull Request #3613 · tianocore/edk2 (github.com)

 

 

Thanks,

Gua

Guo:

 Now, UniversalPayload definitions are in MdeModulePkg\Include\UniversalPayload directory. For example, PCI Root Bridges HOB is defined in MdeModulePkg\Include\UniversalPayload\PciRootBridges.h. So, I think this definition should be placed in the same place.

 

Thanks

Guo:

 MdePkg definitions are from the industry standard. Which document defines TraceHubDebugInfoHob?

Hi Victor

Could you help to move below header file to MdePkg on Maintainer.txt ?

SiliconPkg can build the hob so have the HOB interface is enough. Platform can use TraceHubLib to consume the HOB.

I don’t think that’s the solution to resolve pkg dependencies by adding interfaces to mdePkg.

Based on Green H, we need to let the HOB can be consumed by SiliconPkg so move it from MdeModulePkg to MdePkg.
