From b244c7dc74ba82c687aa0bb67b52943ed951208e Mon Sep 17 00:00:00 2001 From: qwang12 Date: Tue, 9 Jan 2007 08:17:21 +0000 Subject: [PATCH] Add in UefiApplicationEntryPoint library class and library instance. The major difference between UefiApplicationEntryPoint and UefiDriverEntryPoint is that: 1) UEFI application will always be unloaded no matter what is the return status code from the application. Therefore, the library destructors should be called always. 2) UEFI application should not register any callback to evevnt such as EFI_EVENT_GROUP_VIRTUAL_ADDRESS_CHANGE and EFI_EVENT_GROUP_EXIT_BOOT_SERVICES. 3) UEFI application does not support module merger like Uefi Driver. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@2199 6f19259b-4bc3-4df7-8a09-765794883524 --- .../Library/UefiApplicationEntryPoint.h | 129 ++++++++++++++++++ .../ApplicationEntryPoint.c | 103 ++++++++++++++ .../UefiApplicationEntryPoint.msa | 42 ++++++ MdePkg/MdePkg.fpd | 30 ++-- MdePkg/MdePkg.spd | 7 +- 5 files changed, 289 insertions(+), 22 deletions(-) create mode 100644 MdePkg/Include/Library/UefiApplicationEntryPoint.h create mode 100644 MdePkg/Library/UefiApplicationEntryPoint/ApplicationEntryPoint.c create mode 100644 MdePkg/Library/UefiApplicationEntryPoint/UefiApplicationEntryPoint.msa diff --git a/MdePkg/Include/Library/UefiApplicationEntryPoint.h b/MdePkg/Include/Library/UefiApplicationEntryPoint.h new file mode 100644 index 0000000000..ff8b5b241e --- /dev/null +++ b/MdePkg/Include/Library/UefiApplicationEntryPoint.h @@ -0,0 +1,129 @@ +/** @file + Entry point to a UEFI Application. + +Copyright (c) 2007, Intel Corporation
