Add FspMode field from reserved byte of Global > Data Structure to tell which mode is selected by boot > loader. If boot loader invoking FSP-M API this field > will remain as default 0 (API mode), otherwise platform > FSP should set this field to 1 (Dispatch mode) when > initializing Global Data Structure. > 2. gFspInApiModePpiGuid will be instaled when FSP running in API > mode and modules only for API mode should have this in depex. > 3. If it is DISPATCH mode, FSP will return to PEI dispatcher, > not directly return to boot loader. > 4. DISPATCH mode supports DXE NotifyPhase drivers so FSP > will not wait for PEI NotifyPhase callbacks, instead it > will install gFspReadyForNotifyPhasePpiGuid PPI for > platform to complete late initialization before transferring > to DXE. > > Test: Verified FSP API and DISPATCH modes on 2 internal > platforms and both boot successfully. > > Cc: Jiewen Yao <jiewen....@intel.com> > Cc: Desimone Nathaniel L <nathaniel.l.desim...@intel.com> > Contributed-under: TianoCore Contribution Agreement 1.1 > Signed-off-by: Chasel Chiu <chasel.c...@intel.com> > --- > IntelFsp2Pkg/FspNotifyPhase/FspNotifyPhasePeim.c | 59 > +++++++++------- > IntelFsp2Pkg/FspNotifyPhase/FspNotifyPhasePeim.inf | 3 +- > IntelFsp2Pkg/FspSecCore/FspSecCoreM.inf | 2 +- > IntelFsp2Pkg/FspSecCore/SecMain.c | 5 ++ > IntelFsp2Pkg/Include/FspGlobalData.h | 8 ++- > IntelFsp2Pkg/IntelFsp2Pkg.dec | 12 ++++ > .../Library/BaseFspCommonLib/FspCommonLib.c | 22 +++--- > .../Library/BaseFspPlatformLib/FspPlatformNotify.c | 78 > +++++++++++++--------- > 8 files changed, 122 insertions(+), 67 deletions(-) > > diff --git a/IntelFsp2Pkg/FspNotifyPhase/FspNotifyPhasePeim.c > b/IntelFsp2Pkg/FspNotifyPhase/FspNotifyPhasePeim.c > index 52435fa0b2..cbea3a7eaa 100644 > --- a/IntelFsp2Pkg/FspNotifyPhase/FspNotifyPhasePeim.c > +++ b/IntelFsp2Pkg/FspNotifyPhase/FspNotifyPhasePeim.c > @@ -48,6 +48,12 @@ CONST EFI_PEI_PPI_DESCRIPTOR gEndOfPeiSignalPpi > = { > NULL > }; > > +CONST EFI_PEI_PPI_DESCRIPTOR gFspReadyForNotifyPhasePpi = { > + (EFI_PEI_PPI_DESCRIPTOR_PPI | > EFI_PEI_PPI_DESCRIPTOR_TERMINATE_LIST), > + &gFspReadyForNotifyPhasePpiGuid, > + NULL > +}; > + > /** > > This function waits for FSP notify. > @@ -88,13 +94,15 @@ WaitForNotify ( > // > FspWaitForNotify (); > > - // > - // Should not come here > - // > - while (TRUE) { > - DEBUG ((DEBUG_ERROR, "No FSP API should be called after FSP is > DONE!\n")); > - SetFspApiReturnStatus (EFI_UNSUPPORTED); > - Pei2LoaderSwitchStack (); > + if (GetFspGlobalDataPointer ()->FspMode == FSP_IN_API_MODE) { > + // > + // Should not come here > + // > + while (TRUE) { > + DEBUG ((DEBUG_ERROR, "No FSP API should be called after FSP is > DONE!\n")); > + SetFspApiReturnStatus (EFI_UNSUPPORTED); > + Pei2LoaderSwitchStack (); > + } > } > > return EFI_SUCCESS; > @@ -121,22 +129,27 @@ FspNotifyPhasePeimEntryPoint ( > > DEBUG ((DEBUG_INFO | DEBUG_INIT, "The entry of > FspNotificationPeim\n")); > > - // > - // Locate old DXE IPL PPI > - // > - Status = PeiServicesLocatePpi ( > - &gEfiDxeIplPpiGuid, > - 0, > - &OldDescriptor, > - &OldDxeIplPpi > - ); > - ASSERT_EFI_ERROR (Status); > - > - // > - // Re-install the DXE IPL PPI to wait for notify > - // > - Status = PeiServicesReInstallPpi (OldDescriptor, &mInstallDxeIplPpi); > - ASSERT_EFI_ERROR (Status); > + if (GetFspGlobalDataPointer ()->FspMode == FSP_IN_API_MODE) { > + // > + // Locate old DXE IPL PPI > + // > + Status = PeiServicesLocatePpi ( > + &gEfiDxeIplPpiGuid, > + 0, > + &OldDescriptor, > + &OldDxeIplPpi > + ); > + ASSERT_EFI_ERROR (Status); > + > + // > + // Re-install the DXE IPL PPI to wait for notify > + // > + Status = PeiServicesReInstallPpi (OldDescriptor, &mInstallDxeIplPpi); > + ASSERT_EFI_ERROR (Status); > + } else { > + Status = PeiServicesInstallPpi (&gFspReadyForNotifyPhasePpi); > + ASSERT_EFI_ERROR (Status); > + } > > return EFI_SUCCESS; > } > diff --git a/IntelFsp2Pkg/FspNotifyPhase/FspNotifyPhasePeim.inf > b/IntelFsp2Pkg/FspNotifyPhase/FspNotifyPhasePeim.inf > index a0bc37580d..b0f6768cfa 100644 > --- a/IntelFsp2Pkg/FspNotifyPhase/FspNotifyPhasePeim.inf > +++ b/IntelFsp2Pkg/FspNotifyPhase/FspNotifyPhasePeim.inf > @@ -1,7 +1,7 @@ > ## @file > # Component information file for the FSP notify phase PEI module. > # > -# Copyright (c) 2016 - 2017, Intel Corporation.
