As we offline sync, there are below opens like below. Have any open, please also share for us. 1. Need to add TraceHub PCD into edk2/MdeModulePkg.uni at master * tianocore/edk2 * GitHub<https://github.com/tianocore/edk2/blob/master/MdeModulePkg/MdeModulePkg.uni> Answer: Will update it in next patch 1. What about the license ? Answer: It's BSD license, based on public-mipi-sys-t/LICENSE at master * MIPI-Alliance/public-mipi-sys-t (github.com)<https://github.com/MIPI-Alliance/public-mipi-sys-t/blob/master/LICENSE> 1. Is PcdTraceHubDebugAddress MMIO address ? If yes, why we use UINT32 Answer: It's MMIO address, we can change it to UINT64, it make sense to let the PCH more generic. Will update it in next patch. 1. For TraceHubWriteCataLog64_[0-6] try to use below macro to implement it. #define VA_START va_start #define VA_ARG va_arg #define VA_END va_end #define VA_LIST va_list Answer: Will update it in next patch 1. Is have SMM or MM version ? Answer: MdeModulePkg/Library/TraceHubDebugLibSysT/DxeTraceHubDebugLibSyst.inf can take care for SMM case. We can rename it like below to make it more clearly. MdeModulePkg/Library/TraceHubDebugLibSysT/DxeSmmTraceHubDebugLibSyst.inf 1. Whether have any chance to use .gitsubmodule to leverage https://github.com/MIPI-Alliance/public-mipi-sys-t. Answer: Will draft another PR and try to use gitsubmodule to check whether exist any predicament.

It's new added library on Edk2, so it doesn't have any backward and forward issue. May I know have any process we may need to follow up. Have any comment or concern please also share for me.

USF UPL spec update: https://github.com/UniversalScalableFirmware/documentation/pull/52 (Done) Edk2 Bugzilla: https://bugzilla.tianocore.org/show_bug.cgi?id=4144 (On-Going) Edk2 PR: https://github.com/tianocore/edk2/pull/3613 (On-Going) Background: * Problem: In the UPL (Universal Payload) binary which contains only the Edk2 drivers, Tracehub debug message are missing during the execution of early DXE Core modules (before ReportStatusCode is ready). * Solution: Add TraceHub lib on Edk2, to be consumed by the UPL. About TraceHubDebugLibSysT: * Library is consumed by the DebugLib and StatusCodeHandler to send the PostCodes, ProgressCodes and DEBUG messages to the TraceHub/NPK in MIPI SyS-T format. * The MIPI SyS-T APIs in this library are taken from the OpenSource implementation: https://github.com/MIPI-Alliance/public-mipi-sys-t. * Library changes done for upstreaming: MipiSystLib is rewritten to comply EDK2 coding standards and changed ways to pass trace address/verbosity with HOB directly instead of calling into TraceHubHookLib to get these info. * Proposal With UPL: consume HOB gUniversalPayloadTraceHubDebugInfoGuid to print TraceHub Debug message in DXE Core Thanks, Gua -=-=-=-=-=-=-=-=-=-=-=- Groups.io Links: You receive all messages sent to this group.
