From 29c90f14c91bf134a202c1b4ed600c9766bc1411 Mon Sep 17 00:00:00 2001 From: Jeff Fan Date: Fri, 24 Feb 2017 13:58:48 +0800 Subject: [PATCH] UefiCpuPkg/CpuDxe: Do not ASSERT on AllocateMemorySpace() error Platform PEI may add LOCAL APIC memory mapped space into EFI_HOB_MEMORY_ALLOCATION. Or platform may allocate this range before. So, we skip AllocateMemorySpace()'s return status checking. Instead, we add one DEBUG message for possible trace. https://bugzilla.tianocore.org/show_bug.cgi?id=390 This updating is suggested by Ersek's comments at https://www.mail-archive.com/edk2-devel@lists.01.org/msg22585.html Cc: Laszlo Ersek Cc: Star Zeng Cc: Feng Tian Cc: Michael D Kinney Contributed-under: TianoCore Contribution Agreement 1.0 Signed-off-by: Jeff Fan Reviewed-by: Feng Tian Reviewed-by: Star Zeng Reviewed-by: Laszlo Ersek --- UefiCpuPkg/CpuDxe/CpuDxe.c | 10 +++++++++- 1 file changed, 9 insertions(+), 1 deletion(-) diff --git a/UefiCpuPkg/CpuDxe/CpuDxe.c b/UefiCpuPkg/CpuDxe/CpuDxe.c index 2fd2f313a9..4a5e282741 100644 --- a/UefiCpuPkg/CpuDxe/CpuDxe.c +++ b/UefiCpuPkg/CpuDxe/CpuDxe.c @@ -1075,6 +1075,11 @@ AddLocalApicMemorySpace ( Status = AddMemoryMappedIoSpace (BaseAddress, SIZE_4KB, EFI_MEMORY_UC); ASSERT_EFI_ERROR (Status); + // + // Try to allocate APIC memory mapped space, does not check return + // status because it may be allocated by other driver, or DXE Core if + // this range is built into Memory Allocation HOB. + // Status = gDS->AllocateMemorySpace ( EfiGcdAllocateAddress, EfiGcdMemoryTypeMemoryMappedIo, @@ -1084,7 +1089,10 @@ AddLocalApicMemorySpace ( ImageHandle, NULL ); - ASSERT_EFI_ERROR (Status); + if (EFI_ERROR (Status)) { + DEBUG ((DEBUG_INFO, "%a: %a: AllocateMemorySpace() Status - %r\n", + gEfiCallerBaseName, __FUNCTION__, Status)); + } } /**
