Subject: Error during --arch x86_64 kunit test run

David, Brendan, Rae,

I am seeing the following error when I run

./tools/testing/kunit/kunit.py run --arch x86_64

ERROR:root:ld:arch/x86/realmode/rm/realmode.lds:236: undefined symbol `sev_es_trampoline_start' referenced in expression

I isolated it to dependency on CONFIG_AMD_MEM_ENCRYPT

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?

thanks,
-- Shuah
