Subject: Re: [edk2-devel] [PATCH 1/2] KabylakeSiliconPkg: Support DefaultPolicyInit PPI.
Date: Tue, 11 Jun 2019 02:11:24 +0000	[thread overview]
Message-ID: <734D49CCEBEEF84792F5B80ED585239D5C19FDDC@SHSMSX104.ccr.corp.intel.com> (raw)
In-Reply-To: <02A34F284D1DA44BB705E61F7180EF0AAEBD5DA3@ORSMSX114.amr.corp.intel.com>

Chasel,
Where is the code that produces DefaultPolicyInit PPI?
Is the code public available?

And in general, I think the patch consists of several changes:
1. change version compare from "==" to ">=" to support FSP be used in newer board.
2. Add definition of SiDefaultPolicyPpi
3. Update non-FSP version of PeiSiliconPolicyInitLib to consume the SiDefaultPolicyPpi
4. Update config block for GFX
5. Add SiXXXInstallPolicyReadyPpi
6. maybe more....

Can you please try to separate the changes to small patches?

Regarding to the changes in KabylakeSiliconPkg\Library\PeiSiPolicyLib\PeiSiPolicyLibPreMem.c:
There are two APIs: SiPreMemInstallPolicyPpi and SiPreMemInstallPolicyReadyPpi.

When FSP runs in API mode, the calling flow is as below:
FspWrapperPeim::PeiMemoryDiscoveredNotify
--> MinPlatformPkg/../PeiFspWrapperPlatformLib::UpdateFspsUpdData
    --> KabylakeSiliconPkg/.../SiliconPolicyInitPostMem
        --> KabylakeSiliconPkg/.../PeiSiPolicyLib::SiCreateConfigBlocks
        --> KabylakeSiliconPkg/.../PeiSiPolicyLib::SiInstallPolicyPpi

Do you think that it's possible to update KabylakeSiliconPkg/.../SiliconPolicyInitPostMem() to
call SiDefaultPolicyInitPpi->PeiPolicyInit()? To align the behavior when FSP runs in dispatch mode.

Thanks,
Ray
