7439a5 |
|
|

7439a5 |
- No manual / explicit code change is necessary, because the newly

inherited OvmfPkg/AmdSev platform already has its own BUILD_SHELL

7439a5 |
upstream commit b261a30c900a ("OvmfPkg/AmdSev: add Grub Firmware Volume

|

7439a5 |

Bugzilla: 1147592
|
|
|
7439a5 |
|
|
|
7439a5 |
When '-D EXCLUDE_SHELL_FROM_FD' is passed to 'build', exclude the shell
|
|
|
7439a5 |
binary from the firmware image.
|
|
|
7439a5 |
|
|
|
7439a5 |
Peter Jones advised us that firmware vendors for physical systems disable
|
|
|
7439a5 |
the memory-mapped, firmware image-contained UEFI shell in
|
|
|
7439a5 |
SecureBoot-enabled builds. The reason being that the memory-mapped shell
|
|
|
7439a5 |
can always load, it may have direct access to various hardware in the
|
|
|
7439a5 |
system, and it can run UEFI shell scripts (which cannot be signed at all).
|
|
|
7439a5 |
|
|
|
7439a5 |
Intended use of the new build option:
|
|
|
7439a5 |
|
|
|
7439a5 |
- In-tree builds: don't pass '-D EXCLUDE_SHELL_FROM_FD'. The resultant
|
|
|
7439a5 |
firmware image will contain a shell binary, independently of SecureBoot
|
|
|
7439a5 |
enablement, which is flexible for interactive development. (Ie. no
|
|
|
7439a5 |
change for in-tree builds.)
|
|
|
7439a5 |
|
|
|
7439a5 |
- RPM builds: pass both '-D SECURE_BOOT_ENABLE' and
|
|
|
7439a5 |
'-D EXCLUDE_SHELL_FROM_FD'. The resultant RPM will provide:
|
|
|
7439a5 |
|
|
|
7439a5 |
- OVMF_CODE.fd: SecureBoot-enabled firmware, without builtin UEFI shell,
|
|
|
7439a5 |
|
|
|
7439a5 |
- OVMF_VARS.fd: variable store template matching OVMF_CODE.fd,
|
|
|
7439a5 |
|
|
|
7439a5 |
- UefiShell.iso: a bootable ISO image with the shell on it as default
|
|
|
7439a5 |
boot loader. The shell binary will load when SecureBoot is turned off,
|
|
|
7439a5 |
and won't load when SecureBoot is turned on (because it is not
|
|
|
7439a5 |
signed).
|
|
|
7439a5 |
|
|
|
7439a5 |
UefiShell.iso is the reason we're not excluding the shell from the DSC
|
|
|
7439a5 |
files as well, only the FDF files -- when '-D EXCLUDE_SHELL_FROM_FD'
|
|
|
7439a5 |
is specified, the shell binary needs to be built the same, only it
|
|
|
7439a5 |
will be included in UefiShell.iso.
