I haven't found any proper documentation on exactly what I'm trying to achieve so I am probably missing something. Nobody was able to help me there so I turn here for your help.

I'm including quotes from your post to the mailing list since that mailing list is for code review and community management. Without code, we can only give guesses that could be frustrating non-answers for you. If you have a branch of EDK2 that includes your changes and you provide the exact steps you use to build OVMF, then it'll be much easier to help solve the issue.

In order to build OVMF without problems I had to install and use the GCC5 toolchain:Īdding my driver natively makes QEMU hang with: But I find it unlikely that secure boot is the problem given that I can modify the OVMF image through UEFITool. Nonetheless, I am using QEMU with the -bios OVMF.fd option, which according to this post is not supposed to and relates to this secure boot thing. Which seems to imply that secure boot is disabled. These can be changed on the command line. Removing one of the default DXE driver doesn't make it hang, adding it back doesn't make QEMU hang either.įor logs to be written with -D, I also have to provide a -d item, where item is one of -d help, such as int for interrupts.

3 - Build OVMF myself, adding my driver natively 4 - Any other suggestion?Īny help with my previous attempts would also be kindly appreciatted. This question says that OVMF_CODE.fd allows secure boot to be comprised, but I haven't been able to find a OVMF_CODE file.

Further attempts 1 - Find out how to get QEMU logs 2 - Find out how to disable secure boot But I haven't been able to understand how to do that yet. If I manage to get the vanilla version working I'd then add my driver natively. I tried to build OMVF.fd with edk2, but the build has errors. This is not allowing the modified firmware image to run. If I had to pick a reason, I'd say that secure boot is enabled. I have also tried to hook gdb to QEMU with the -S -s flags, but looking at assembly didn't help me understand what is failing. I have tried to use -D log.txt, but no logs are written. Unfortunately, when I try to boot that bios with QEMU, the system hangs with the message Guest has not initialized the display yet. Instead of extracting VMWare's bios.rom, I used UEFITool on OVMF.fd to the same end.

This trick doesn't seem to work anymore as detailed in this issue. I have followed the vmware-vmx.exe injection guide suggested in the previous link.
