From 495797c5578e88cd1a769e918502cf426f08d6b0 Mon Sep 17 00:00:00 2001 From: rsun3 Date: Tue, 16 Aug 2011 02:58:20 +0000 Subject: 1. Add two performance measurement points for SMM performance measurement; 2. Introduce SmmCorePlatformHookLib library class defining two platform hook points. Update PI Smm Core to call the hook points before and after invoking registered SMI handlers. A NULL instance of this library class is implemented. Note that after this check in, DSC files consuming the PiSmmCore.inf need to be updated to add a library instance for SmmCorePlatformHookLib library class. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@12140 6f19259b-4bc3-4df7-8a09-765794883524 --- MdeModulePkg/Core/PiSmmCore/PiSmmCore.c | 16 ++++++- MdeModulePkg/Core/PiSmmCore/PiSmmCore.h | 4 +- MdeModulePkg/Core/PiSmmCore/PiSmmCore.inf | 6 ++- .../Include/Library/SmmCorePlatformHookLib.h | 50 +++++++++++++++++++++ .../SmmCorePlatformHookLibNull.c | 52 ++++++++++++++++++++++ .../SmmCorePlatformHookLibNull.inf | 35 +++++++++++++++ MdeModulePkg/MdeModulePkg.dec | 4 ++ MdeModulePkg/MdeModulePkg.dsc | 4 +- 8 files changed, 166 insertions(+), 5 deletions(-) create mode 100644 MdeModulePkg/Include/Library/SmmCorePlatformHookLib.h create mode 100644 MdeModulePkg/Library/SmmCorePlatformHookLibNull/SmmCorePlatformHookLibNull.c create mode 100644 MdeModulePkg/Library/SmmCorePlatformHookLibNull/SmmCorePlatformHookLibNull.inf (limited to 'MdeModulePkg') diff --git a/MdeModulePkg/Core/PiSmmCore/PiSmmCore.c b/MdeModulePkg/Core/PiSmmCore/PiSmmCore.c index 75337f6..a5e4b6e 100644 --- a/MdeModulePkg/Core/PiSmmCore/PiSmmCore.c +++ b/MdeModulePkg/Core/PiSmmCore/PiSmmCore.c @@ -1,7 +1,7 @@ /** @file SMM Core Main Entry Point - Copyright (c) 2009 - 2010, Intel Corporation.
