## @file # # Driver for dumping boot loader UEFI calls. # # By dmazar, 26/09/2012 # # Feel free to use it, debug it, extend it, but please report back changes/additions to # http://www.projectosx.com/ # # How to use: # # Users of Clover boot manager can just place the driver to appropriate drivers folder # (for example /EFI/CLOVER/drivers64). Other users will probably know how to load it. # # How it works: # # Driver overrides gBS->StartImage() in order to be able to detect boot loader starting (DumpUefiCalls.c). # # When boot loader is about te be started, driver overrides all boot (gBS) and runtime (gRT) services # with small wrappers that will call original plartform services and log each call (BootServices.c, RuntimeServices.c). # # When ExitBootServices() is called driver will also print UEFI system table (with configuration tables) # and UEFI variables (RT vars). # # Logging is done through PRINT definition (Common.h) which gets replaced by LogPrint() (Log.c). # Logs can be directed to screen, serial and disk file (LOG_TO_SCREEN, LOG_TO_SERIAL, LOG_TO_FILE in Common.h). # # Logs to serial are interesting when used in VBox (VMWare?, QEmu?) because driver can continue to dump UEFI # calls even during runtime phase, after ExitBootServices() and when OS is running. # This requires WORK_DURING_RUNTIME to be enabled in Common.h. That is also a reason why is driver made as runtime driver. # # Logs to screen and file work only up to ExitBootServices() because they depend on boot services to be running. # # PRINT_SHELL_VARS in Common.h is set to 0 to avoid dumping of uninteresting shell vars data. Can be set to 1. # ## [Defines] INF_VERSION = 0x00010005 BASE_NAME = DumpUefiCalls FILE_GUID = B7F22AE1-9D87-4CD6-8EB1-171573908835 # MODULE_TYPE = UEFI_DRIVER MODULE_TYPE = DXE_RUNTIME_DRIVER VERSION_STRING = 1.0 ENTRY_POINT = DumpUefiCallsEntrypoint # # The following information is for reference only and not required by the build tools. # # VALID_ARCHITECTURES = X64|IA32 # [Packages] MdePkg/MdePkg.dec IntelFrameworkPkg/IntelFrameworkPkg.dec CloverPkg.dec [LibraryClasses] UefiLib UefiBootServicesTableLib UefiRuntimeServicesTableLib BaseMemoryLib MemoryAllocationLib UefiDriverEntryPoint BaseLib DevicePathLib DebugLib [Sources] DumpUefiCalls.c Lib.h Lib.c BootServices.h BootServices.c RuntimeServices.h RuntimeServices.c Log.h Log.c MemLog.h MemLog.c FileLib.h FileLib.c DataHub.h DataHub.c Fs.h Fs.c AppleProtocols.c AppleProtocols.h Common.h [Guids] gEfiFileInfoGuid gEfiFileSystemInfoGuid gEfiFileSystemVolumeLabelInfoIdGuid gEfiEventVirtualAddressChangeGuid gEfiAcpi10TableGuid gEfiAcpi20TableGuid gEfiDebugImageInfoTableGuid gEfiDxeServicesTableGuid gEfiHobListGuid gEfiMpsTableGuid gEfiSmbiosTableGuid gEfiSmbios3TableGuid gEfiPartTypeSystemPartGuid [Protocols] gEfiLoadedImageProtocolGuid gEfiDevicePathProtocolGuid gEfiSimpleFileSystemProtocolGuid gEfiBlockIoProtocolGuid gEfiBlockIo2ProtocolGuid gEfiDiskIoProtocolGuid gEfiDiskIo2ProtocolGuid gEfiGraphicsOutputProtocolGuid gEfiDataHubProtocolGuid gEfiFirmwareVolumeProtocolGuid gAppleSMCProtocolGuid gAppleImageCodecProtocolGuid gAppleKeyStateProtocolGuid gEfiOSInfoProtocolGuid gAppleGraphConfigProtocolGuid gEfiKeyboardInfoProtocolGuid gAppleKeyMapDatabaseProtocolGuid gEfiSimplePointerProtocolGuid [Depex] TRUE [BuildOptions] # MSFT:*_*_*_ASM_FLAGS = /Fl INTEL:DEBUG_*_*_CC_FLAGS = INTEL:RELEASE_*_*_CC_FLAGS = /D MDEPKG_NDEBUG GCC:DEBUG_*_*_CC_FLAGS = GCC:RELEASE_*_*_CC_FLAGS = -DMDEPKG_NDEBUG MSFT:DEBUG_*_*_CC_FLAGS = MSFT:RELEASE_*_*_CC_FLAGS = /D MDEPKG_NDEBUG XCODE:DEBUG_*_*_CC_FLAGS = XCODE:RELEASE_*_*_CC_FLAGS = -DMDEPKG_NDEBUG
