Subject: Re: [edk2-platform patch 2/7] SimicsICH10Pkg: Add PCH Pkg for SimicsICH10
Date: Tue, 20 Aug 2019 01:04:12 +0000 [thread overview]
Message-ID: <49AB4ACB9627B8468F29D589A27B745588A50010@ORSMSX122.amr.corp.intel.com> (raw)
In-Reply-To: <05fcb438dacd1d3d637dd7bf8f2df5bc2062bd5e.1565389186.git.david.y.wei@intel.com>
Feedback I could not find already noted elsewhere:
1. /Silicon/Intel/SimicsICH10Pkg/LibraryPrivate/BasePchSpiCommonLib/BasePchSpiCommonLib.inf:
This silicon package should not have a dependency on MinPlatformPkg.dec.
2. /Silicon/Intel/SimicsICH10Pkg/LibraryPrivate/BasePchSpiCommonLib/BasePchSpiCommonLib.inf:
This silicon package should not have a dependency on SimicsOpenBoardPkg.dec.
3. Although noted elsewhere: I also prefer Pascal naming as well so SimicsIch10Pkg.
4. /Silicon/Intel/SimicsICH10Pkg/Library/ResetSystemLib/ResetSystemLib.c:
"Reset System Library functions for OVMF" - replace OVMF with Simics ICH10.
5. /Silicon/Intel/SimicsICH10Pkg/Library/ResetSystemLib/ResetSystemLib.inf:
This silicon package INF should not have a dependency on MinPlatformPkg.dec.
6. /Silicon/Intel/SimicsICH10Pkg/SmmControl/RuntimeDxe/SmmControl2Dxe.inf
This silicon package INF should not have a dependency on MinPlatformPkg.dec.
7. /Silicon/Intel/SimicsICH10Pkg/Library/SmmSpiFlashCommonib/SmmSpiFlashCommonLib:
This silicon package INF should not have a dependency on MinPlatformPkg.dec.

> +
> + - @pre
> + - EFI_SMM_BASE2_PROTOCOL
> + - Documented in System Management Mode Core Interface Specification .

> + The SPI SMM driver produces @link _PCH_SPI_PROTOCOL
> PCH_SPI_PROTOCOL @endlink with GUID
> + gPchSmmSpiProtocolGuid which is different from SPI RUNTIME driver.
> +
> + - <b>Integration Check List</b>\n
> + - This driver supports Descriptor Mode only.
> + - This driver supports Hardware Sequence only.
> + - When using SMM SPI Protocol to perform flash access in an SMI handler,
> + and the SMI occurrence is asynchronous to normal mode code execution,
> + proper synchronization mechanism must be applied, e.g. disable SMI before
> + the normal mode SendSpiCmd() starts and re-enable SMI after
> + the normal mode SendSpiCmd() completes.
> + @note The implementation of SendSpiCmd() uses GBL_SMI_EN in
> + SMI_EN register (ABase + 30h) to disable and enable SMIs. But this may
> + not be effective as platform may well set the SMI_LOCK bit (i.e., PMC PCI
> Offset A0h [4]).
> + So the synchronization at caller level is likely needed.
