Is there a way to get the architecture of the machine just booted up by GRUB2: [32|64]-[amd|arm]? ...

[Albretch Mueller]

I can't find it in the documentation:

https://www.gnu.org/software/grub/manual/grub/grub.html

https://www.mail-archive.com/search?l=help-grub%40gnu.org&q=architecture+amd64

you could deduce via dmidecode if a machine is 32- or 64-bit, and,
say, in Debian Linux, after boot up you can get the processor type
from the OS by running:

$ dpkg --print-architecture
amd64

$ uname -a
Linux debian 5.10.0-18-amd64 #1 SMP Debian 5.10.140-1 (2022-09-02)
x86_64 GNU/Linux

How could you get the architecture it is running on from GRUB2?
