From 4199d92d1c5e2231e596e25a27acaffefa72a064 Mon Sep 17 00:00:00 2001 From: yshang1 Date: Thu, 11 Oct 2007 11:12:28 +0000 Subject: Add BasePalCallLibNull instance in MdePkg. It is useful when building IPF components in open source packages. Use meaningful arguments defined in PalLib.h when invoking PalCall(). git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@4094 6f19259b-4bc3-4df7-8a09-765794883524 --- MdePkg/Library/BaseCacheMaintenanceLib/IpfCache.c | 6 +-- .../BasePalCallLibNull/BasePalCallLibNull.inf | 42 ++++++++++++++++ MdePkg/Library/BasePalCallLibNull/PalCall.c | 58 ++++++++++++++++++++++ MdePkg/Library/SecPeiDxeTimerLibCpu/IpfTimerLib.c | 4 +- 4 files changed, 105 insertions(+), 5 deletions(-) create mode 100644 MdePkg/Library/BasePalCallLibNull/BasePalCallLibNull.inf create mode 100644 MdePkg/Library/BasePalCallLibNull/PalCall.c (limited to 'MdePkg/Library') diff --git a/MdePkg/Library/BaseCacheMaintenanceLib/IpfCache.c b/MdePkg/Library/BaseCacheMaintenanceLib/IpfCache.c index 1007b4448f..17ef43d968 100644 --- a/MdePkg/Library/BaseCacheMaintenanceLib/IpfCache.c +++ b/MdePkg/Library/BaseCacheMaintenanceLib/IpfCache.c @@ -36,7 +36,7 @@ InvalidateInstructionCache ( VOID ) { - PalCall (1, 1, 1, 0); + PalCall (PAL_CACHE_FLUSH, PAL_CACHE_FLUSH_INSTRUCTION_ALL, PAL_CACHE_FLUSH_INVALIDATE_LINES, 0); } /** @@ -90,7 +90,7 @@ WriteBackInvalidateDataCache ( VOID ) { - PalCall (1, 2, 1, 0); + PalCall (PAL_CACHE_FLUSH, PAL_CACHE_FLUSH_DATA_ALL, PAL_CACHE_FLUSH_INVALIDATE_LINES, 0); } /** @@ -147,7 +147,7 @@ WriteBackDataCache ( VOID ) { - PalCall (1, 2, 0, 0); + PalCall (PAL_CACHE_FLUSH, PAL_CACHE_FLUSH_DATA_ALL, PAL_CACHE_FLUSH_NO_INVALIDATE_LINES | PAL_CACHE_FLUSH_NO_INTERRUPT, 0); } /** diff --git a/MdePkg/Library/BasePalCallLibNull/BasePalCallLibNull.inf b/MdePkg/Library/BasePalCallLibNull/BasePalCallLibNull.inf new file mode 100644 index 0000000000..8de1890eb1 --- /dev/null +++ b/MdePkg/Library/BasePalCallLibNull/BasePalCallLibNull.inf @@ -0,0 +1,42 @@ +#/** @file +# Component description file for NULL Debug Library +# +# Debug Library with empty functions. +# Copyright (c) 2007, Intel Corporation. +# +# All rights reserved.
