Add support for the ImageCapsuleSupport field, introduced in version 3
of the EFI_FIRMWARE_MANAGEMENT_CAPSULE_IMAGE_HEADER structure. This
structure member is used to indicate if the corresponding payload has
support for authentication and dependency.

Hi, I think this patch is functional, but there are a few things that can be improved. 1) We should not use of the hard coded constants for the ImageCapsuleSupport values. The UEFI spec has #defines for these values, and we need to figure out how to add those define values in the scope of the FMP Capsule Image Header. Perhaps add the values to FmpCapsuleImageHeaderClass in FmpCapsuleHeader.py: class FmpCapsuleImageHeaderClass (object): CAPSULE_SUPPORT_AUTHENTICATION = 0x0000000000000001 CAPSULE_SUPPORT_DEPENDENCY = 0x0000000000000002 From GenerateCapsule.py, you can use these values to set ImageCapsuleSupport. Value 0 is not defined by the UEFI Spec. Though that appears to be the value used for a raw payload without authentication or dependency information. Since GenerateCapsule does not import FmpCapsuleImageHeaderClass, these defines may have to be added to the FmpCapsuleHeaderClass instead. 2) The ImageCapsuleSupport parameter is added in the middle of the python function arguments. Since this is a new field added at the end of the V3 structure, I recommend we add arguments at the end of the argument list. This will be an optional argument, so any existing use of these methods for V2 use cases will not be impacted. These python methods can be potentially used by other consumers, so we should always consider backwards compatibility when updating BaseTools/Source/Python/Common areas.

If you look at the code, the way it is right now, the EFI_FIRMWARE_MANAGEMENT_CAPSULE_IMAGE_HEADER structure currently supports version 2 -- there is no provision for generating a capsule with version 1 for example. So the way the code is structured right now, we can only support one version. So, if you are looking for having support for previous versions as well, I think that would require adding support for passing the structure version that we need, and then based on. this information, the structure would have certain fields present/absent. Would it be fine to add this field in the structure for now. If you think it necessary, support for multiple versions of the structure can be added as a separate exercise. Is my understanding of your comment correct, or am I missing something. -sughosh > > Thanks, > > Mike > > > -----Original Message----- > > From: devel@edk2.groups.io <devel@edk2.groups.io> On Behalf Of Sughosh > Ganu > > Sent: Monday, April 19, 2021 4:40 AM > > To: devel@edk2.groups.io > > Cc: Feng, Bob C <bob.c.feng@intel.com>; Liming Gao < > gaoliming@byosoft.com.cn>; Chen, Christine <yuwei.chen@intel.com>; > > Sughosh Ganu <sughosh.ganu@linaro.org> > > Subject: [edk2-devel] [PATCH] BaseTools: GenerateCapsule.py: Add support > for version 3 of FMP Image Header structure > > > > Add support for the ImageCapsuleSupport field, introduced in version 3 > > of the EFI_FIRMWARE_MANAGEMENT_CAPSULE_IMAGE_HEADER structure.

Sughosh, My feedback on compatibility was for the parameter list to the Python methods. Not the C structures. The python modules in the Common directory could be used by other tools.

On Tue, 20 Apr 2021 at 21:26, Kinney, Michael D <michael.d.kinney@intel.com<mailto:michael.d.kinney@intel.com>> wrote: Hi, I think this patch is functional, but there are a few things that can be improved. 1) We should not use of the hard coded constants for the ImageCapsuleSupport values. The UEFI spec has #defines for these values, and we need to figure out how to add those define values in the scope of the FMP Capsule Image Header. Perhaps add the values to FmpCapsuleImageHeaderClass in FmpCapsuleHeader.py: class FmpCapsuleImageHeaderClass (object): CAPSULE_SUPPORT_AUTHENTICATION = 0x0000000000000001 CAPSULE_SUPPORT_DEPENDENCY = 0x0000000000000002 From GenerateCapsule.py, you can use these values to set ImageCapsuleSupport. Value 0 is not defined by the UEFI Spec. Though that appears to be the value used for a raw payload without authentication or dependency information. Since GenerateCapsule does not import FmpCapsuleImageHeaderClass, these defines may have to be added to the FmpCapsuleHeaderClass instead. Okay. I will make the changes as per your suggestion. 2) The ImageCapsuleSupport parameter is added in the middle of the python function arguments. Since this is a new field added at the end of the V3 structure, I recommend we add arguments at the end of the argument list. This will be an optional argument, so any existing use of these methods for V2 use cases will not be impacted. These python methods can be potentially used by other consumers, so we should always consider backwards compatibility when updating BaseTools/Source/Python/Common areas. I believe that adding support for compatibility with previous versions will be a more involved effort. If you look at the code, the way it is right now, the EFI_FIRMWARE_MANAGEMENT_CAPSULE_IMAGE_HEADER structure currently supports version 2 -- there is no provision for generating a capsule with version 1 for example.
