Hello, I'm trying to use SPDM over DOE as a EDKII_DEVICE_SECURITY_PROTOCOL implementation.
I'm using the DeviceSecurity fork from staging, with my own DOE implementation [5]. First I load `DeviceSecurityPolicyStub` [1], which consumes `gEdkiiDeviceIdentifierTypePci Guid` and produces `gEdkiiDeviceSecurityPolicyProtocolGuid`. Then I am loading `SpdmDeviceSecurityDxe` [2], which consumes `gEdkiiDeviceSecurityPolicyProtocolGuid` and produces `gEdkiiDeviceSecurityProtocolGuid`. At which point I think the `gEdkiiDeviceSecurityProtocolGuid` should work in PciBus [3]. Except the problem is that the PCIe bus is already probed as `DeviceSecurityPolicyStub` consumes `gEdkiiDeviceIdentifierTypePciGuid`. So I get stuck in a circular loop. Does anyone know how I can re-probe the `PciBusDxe` or somehow avoid the circular dependency? Or asking another way, is there a way to call the `AuthenticatePciDevice()` [4] function after probing a PCIe device and determining that the PCIe device supports DOE and SPDM? I don't see any users of `gEfiDevicePathProtocolGuid` in upstream EDK2. 1: https://github.com/tianocore/edk2-staging/blob/DeviceSecurity/DeviceSecurityTestPkg/Test/DeviceSecurityPolicyStub/DeviceSecurityPolicyStub.inf#L36 2: https://github.com/tianocore/edk2-staging/blob/DeviceSecurity/DeviceSecurityTestPkg/SpdmDeviceSecurityDxe/SpdmDeviceSecurityDxe.inf#L56 3: https://github.com/tianocore/edk2-staging/blob/DeviceSecurity/MdeModulePkg/Bus/Pci/PciBusDxe/PciBus.c#L299 4: https://github.com/tianocore/edk2-staging/blob/DeviceSecurity/MdeModulePkg/Bus/Pci/PciBusDxe/PciEnumeratorSupport.c#L2085 5: https://github.com/tianocore/edk2/pull/5715 PS: This is the second mail, the first didn't make it to the list Alistair -=-=-=-=-=-=-=-=-=-=-=- Groups.io Links: You receive all messages sent to this group.
