Egor, The edk2 build tools have a tendency to throw if they find syntax errors, just like if they had internal errors. In this case I think the issue is in the repo? '/home/edk2-msm/Platform/goole/msm8998/taimen.dsc’ Maybe `goole` should be `Google` ? Thanks, Andrew Fish > On May 13, 2024,

Re: [edk2-devel] ovmf miscompiles with gcc-12

Mike, This sounds like a conversation we had years ago? I think we concluded we needed to write stuff in assembler and not depend on implementation choices of the compiler with regard to registers usage? I want to say something broke with Xcode clang. I think it might have been the Emulator

[edk2-devel] [ArmVirtPkg] So in 2014 would could not start an ARM FV @ address 0x00000000, why is that still true today?

I’m a little confused on why we can’t put an ARM FV at address 0x [1]? Obviously the zero vector for the FV is getting patch as this ARM code is jumping to the 1st byte of the FV when it is present at 0x1000. I don’t know of any generic limitation in our tools. This kind of feels like

[edk2-devel] Can you create a PCI Option ROM and place it in an FV in a single build?

I realize I can use syntax like this to control the construction of an option ROM from an FDF file. 1 [OptionRom.AtapiPassThru] 2 INF USE = IA32 OptionRomPkg/AtapiPassThruDxe/AtapiPassThruDxe.inf { 3 PCI_REVISION = 0x0020 4 PCI_DEVICE_ID = 0x0A03 0x0B03 5 } 6 INF USE = EBC

Re: [edk2-devel] Debug OVMF

Sebastien, The UEFI ROMs generally contain sets of PE/COFF images (drivers, apps, etc) that execute not at their linked address. These PE/COFF images have been stripped of debug information and optionally contain a PE/COFF debug directory entry that points to a file that contains the debug

[edk2-devel] Unit Test and sanitizers

Just throwing out an idea for the edk2 unit tests. At least for clang you can turn on the sanitizer via a simple command line flag to the compiler. So seems it would make sense to turn on it for unit tests? I’m not sure if the Linux clang, and maybe even some versions of gcc support this too?
