Subject: RE: [edk2-devel] [PATCH v2] EmulatorPkg: Enable support for Secure Boot

Hi Ray,

Yes, I have tested the following:


  1.  SECURE_BOOT_ENABLE=true

  *   Key Enrollment (PK, KEK, db) via custom mode
  *   Execution of unit test shell application (signed one works okay, unsigned gives an Access denied)


  1.  SECURE_BOOT_ENABLE=false (default case)

  *   Secure Boot Configuration menu is not visible (Same as existing default case)
  *   Execution of Unit Test Application (Signed/Unsigned both works okay)

I am planning to post the script in BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=2949 in a day or too.
The script generates the full key hierarchy that makes it easy to test this patch.
The patch in BZ requires modifications as per Mike's comment, so, you can skip the patches in BZ for now.

Regards,
Divneil

Divneil,
Just want to double confirm: did you test the secure boot and non-secure boot?

Thanks,
Ray
