Ah I've seen this once but it disappeared as I tried to investigate and I've since changed the implementation, so I don't have many notes about it. Maybe you could try to bisect from "ArmVirtPkg: ArmCcaIoMmu: Provide an implementation for SetAttribute", but it may give false positives if the error depends on some random linker placement. Could be "ArmVirtPkg/ArmPlatformLibQemu: Setup early UART mapping in a Realm" which adds a 4k page to the data section for the ealy RSI config call, though that has explicit 4kB alignment. In my notes I also wrote that changing "-z common-page-size=0x20" to 4k in the link flags may have made the error disappear, but I doubt it's the right fix. I'll try GCC 11 to see if I can reproduce. > GenFw: ERROR 3000: Invalid > : > > > > build -b DEBUG -a AARCH64 -t GCC5 -p ArmVirtPkg/ArmVirtQemu.dsc > > > : > > > WriteSections64(): > > > /home/gavin/sandbox/CCA/edk2-guest/Build/ArmVirtQemu-AARCH64/DEBUG_GCC5/AARCH64/ArmPlatformPkg/PrePeiCore/PrePeiCoreUniCore/DEBUG/ArmPlatformPrePeiCore.dll > > > AARCH64 small code model requires identical ELF and PE/COFF section > > > offsets modulo 4 KB. > > > cp -p -f > > > /home/gavin/sandbox/CCA/edk2-guest/Build/ArmVirtQemu-AARCH64/DEBUG_GCC5/AARCH64/OvmfPkg/VirtioFsDxe/VirtioFsDxe/DEBUG/VirtioFsDxe.dll > > > > > > /home/gavin/sandbox/CCA/edk2-guest/Build/ArmVirtQemu-AARCH64/DEBUG_GCC5/AARCH64/OvmfPkg/VirtioFsDxe/VirtioFsDxe/DEBUG/VirtioFsDxe.debug > > > cp -p -f > > > /home/gavin/sandbox/CCA/edk2-guest/Build/ArmVirtQemu-AARCH64/DEBUG_GCC5/AARCH64/MdeModulePkg/Universal/Disk/PartitionDxe/PartitionDxe/DEBUG/PartitionDxe.debug > > > > > > /home/gavin/sandbox/CCA/edk2-guest/Build/ArmVirtQemu-AARCH64/DEBUG_GCC5/AARCH64/PartitionDxe.debug > > > "gcc" -MMD -MF > > > /home/gavin/sandbox/CCA/edk2-guest/Build/ArmVirtQemu-AARCH64/DEBUG_GCC5/AARCH64/CryptoPkg/Library/OpensslLib/OpensslLibCrypto/OUTPUT/openssl/crypto/asn1/x_sig.obj.deps > > > > > > @/home/gavin/sandbox/CCA/edk2-guest/Build/ArmVirtQemu-AARCH64/DEBUG_GCC5/AARCH64/CryptoPkg/Library/OpensslLib/OpensslLibCrypto/OUTPUT/cc_resp.txt > > > -c -o > > > /home/gavin/sandbox/CCA/edk2-guest/Build/ArmVirtQemu-AARCH64/DEBUG_GCC5/AARCH64/CryptoPkg/Library/OpensslLib/OpensslLibCrypto/OUTPUT/openssl/crypto/asn1/x_sig.obj > > > > > > /home/gavin/sandbox/CCA/edk2-guest/CryptoPkg/Library/OpensslLib/openssl/crypto/asn1/x_sig.c > > > "GenFw" -e DXE_CORE -o > > > /home/gavin/sandbox/CCA/edk2-guest/Build/ArmVirtQemu-AARCH64/DEBUG_GCC5/AARCH64/MdeModulePkg/Core/Dxe/DxeMain/OUTPUT/DxeCore.efi > > > > > > /home/gavin/sandbox/CCA/edk2-guest/Build/ArmVirtQemu-AARCH64/DEBUG_GCC5/AARCH64/MdeModulePkg/Core/Dxe/DxeMain/DEBUG/DxeCore.dll > > > GenSec -s EFI_SECTION_USER_INTERFACE -n ArmCpuDxe -o > > > /home/gavin/sandbox/CCA/edk2-guest/Build/ArmVirtQemu-AARCH64/DEBUG_GCC5/FV/Ffs/B8D9777E-D72A-451F-9BDB-BAFB52A68415ArmCpuDxe/B8D9777E-D72A-451F-9BDB-BAFB52A68415SEC3.ui > > > cp -p -f > > > /home/gavin/sandbox/CCA/edk2-guest/Build/ArmVirtQemu-AARCH64/DEBUG_GCC5/AARCH64/MdeModulePkg/Universal/DisplayEngineDxe/DisplayEngineDxe/DEBUG/*.map > > > > > > /home/gavin/sandbox/CCA/edk2-guest/Build/ArmVirtQemu-AARCH64/DEBUG_GCC5/AARCH64/MdeModulePkg/Universal/DisplayEngineDxe/DisplayEngineDxe/OUTPUT > > > cp -p -f > > > /home/gavin/sandbox/CCA/edk2-guest/Build/ArmVirtQemu-AARCH64/DEBUG_GCC5/AARCH64/MdeModulePkg/Universal/Disk/UdfDxe/UdfDxe/OUTPUT/UdfDxe.efi > > > > > > /home/gavin/sandbox/CCA/edk2-guest/Build/ArmVirtQemu-AARCH64/DEBUG_GCC5/AARCH64/MdeModulePkg/Universal/Disk/UdfDxe/UdfDxe/DEBUG > > > GenFw: ERROR 3000: Invalid > > > : > > > build.py... > > > : error 7000: Failed to execute command > > > make tbuild > > > [/home/gavin/sandbox/CCA/edk2-guest/Build/ArmVirtQemu-AARCH64/DEBUG_GCC5/AARCH64/ArmPlatformPkg/PrePeiCore/PrePeiCoreUniCore] > > > > > > > > > build.py... > > > : error F002: Failed to build module > > > > > > /home/gavin/sandbox/CCA/edk2-guest/ArmPlatformPkg/PrePeiCore/PrePeiCoreUniCore.inf > > > [AARCH64, GCC5, DEBUG] > > > > > > - Failed - > > > Build end time: 05:42:19, Jun.01 2024 > > > Build total time: 00:00:31 > > > > Ok, I can look into this deeply after I can bring up the guest successfully. Note that the guest edk2 is optional and experimental, you can use direct kernel boot to get a working demo quicker. Thanks, Jean
