I recall seeing this issue briefly about a year ago on an internal branch, and we worked around it there by enabling CONFIG_AMD_MEM_ENCRYPT (which worked). But I've been totally unable to reproduce it this morning: are you seeing this on any particular branch / config / environment? Either way, I think KUnit _should_ work with AMD_MEM_ENCRYPT disabled (and still does for me here), so the correct fix is probably somewhere in x86-land. > I added the option using --kconfig_add > > ./tools/testing/kunit/kunit.py run --arch x86_64 --kconfig_add CONFIG_AMD_MEM_ENCRYPT=y > > I see the following > > RROR:root:Not all Kconfig options selected in kunitconfig were in the generated .config. > This is probably due to unsatisfied dependencies. > Missing: CONFIG_AMD_MEM_ENCRYPT=y > > Is there a better way to fix the dependencies? Does kunit default config > need changing for x86_64? Looks like this requires CONFIG_EFI=y and CONFIG_EFI_STUB=y as well. I've had success building with: --kconfig_add CONFIG_AMD_MEM_ENCRYPT=y --kconfig_add CONFIG_EFI_STUB=y --kconfig_add CONFIG_EFI=y As for defaults. I'd hope we don't _need_ them, and that the root cause of the issue can be fixed, but I'm happy to add those to the defaults in tools/testing/kunit/qemu_configs/x86_64.py if we can't resolve the underlying issue. -- David
