[Buildroot] UEFI and systemD

[Buildroot] UEFI and systemD

[lpdev at cordier.org]

Hi everybody,

I finally succeed to compile and start a linux kernel using EFI. My kernel is booting, but it seems that systemd is not starting. (I only get output from the kernel, and when I plugin/plugoff devices). I have no tty for interacting with the operating system.

After digging in systemd.mk, I noticed that in SYSTEMD_CONF_OPTS, 2 options are disabled:

??? -Defi=false \
??? -Dgnu-efi=false \

Is it normal? Any clue to how to make systemd boot while using Uefi?

Following is my defconfig. Thank you very much for your time.

 Try setting those options to true and see if it helps...

 The -Defi=false option has been there since the option was introduced in the
bump from 44 to 207. Probably just not something considered relevant at the time.

 The -Dgnu-efi=false was introduced in ac0a31090ad44531fd14a3e3b1bb7e23c1577f68
with the following explanation:

    - Add --disable-gnuefi to configure options to avoid a failure like this
      one:

      checking for /usr/lib/gnuefi/elf_ia32_efi.lds... configure: error:
      cannot check for file existence when cross compiling

 With the switch to meson, that's probably not relevant anymore and it should
instead become something like this:

ifeq ($(BR2_PACKAGE_GNU_EFI),y)
SYSTEMD_DEPENDENCIES += gnu-efi
SYSTEMD_CONF_OPTS += -Dgnu-efi=true
else
SYSTEMD_CONF_OPTS += -Dgnu-efi=false
endif


 If you do get success with these changes, could you send two patches to
Buildroot? The first one to enable the optional gnu-efi dependency, the second
one to enable efi when appropriate. For the latter, of course, you should first
find out when it is appropriate to enable efi.


 Regards,
 Arnout
