Hi Justin,
The EDK II tools should support a binary INF file that has both the drive and
the compiled depex file in the [Binaries] section.
Using the PcAtChipsetPkg/PcatRealTimeClockRuntimeDex.inf as an example, a valid
INF for the binary would looks like:
[Defines]
INF_VERSION = 0x00010016
BASE_NAME = PcRtc
FILE_GUID = 378D7B65-8DA9-4773-B6E4-A47826A833E1
MODULE_TYPE = DXE_RUNTIME_DRIVER
VERSION_STRING = 1.0
[Binaries.IA32]
PE32|Ia32/PcRtc.efi
DXE_DEPEX|Ia32/PcRtc.depex
The tools do not support building a source depex file without building the
module from source.
The tools will ignore the sources section if a [Binaries] section does exist;
so the following is not valid:
[Defines]
INF_VERSION = 0x00010016
BASE_NAME = PcRtc
FILE_GUID = 378D7B65-8DA9-4773-B6E4-A47826A833E1
MODULE_TYPE = DXE_RUNTIME_DRIVER
VERSION_STRING = 1.0
DPX_SOURCE = myDepexSrc.depex
[Binaries.IA32]
PE32|Ia32/PcRtc.efi
Nor can you specify a [Depex] section in an INF file that has the binary efi
file. The following is also not valid
[Defines]
INF_VERSION = 0x00010016
BASE_NAME = PcRtc
FILE_GUID = 378D7B65-8DA9-4773-B6E4-A47826A833E1
MODULE_TYPE = DXE_RUNTIME_DRIVER
VERSION_STRING = 1.0
[Binaries.IA32]
PE32|Ia32/PcRtc.efi
[Depex]
gEfiVariableArchProtocolGuid AND gEfiVariableWriteArchProtocolGuid
Cheers,
Larry

Subject: Re: [edk2-buildtools] [edk2] binary-only modules and [depex] sections
Sounds like a bug to me.
Thanks,

Hi all,
I have some binary-only drivers with dependency expressions that are not being
processed. These drivers are not UEFI model drivers.
I see in WorkspaceDatabase.py:
# If the module has only Binaries and no Sources, then ignore [Depex]
if self.Sources == None or self.Sources == []:
if self.Binaries != None and self.Binaries != []:
return self._Depex
The intent being obvious from the comment (comes from SVN revision 2135 of
edk2-buildtools repo). My question is, why are the [Depex] sections ignored
from INFs with only binaries? I don't see in any of the EDKII documentation
where this is stated. Is this a behavior that could be changed?
