Hi Pu, thank you this mirrorm it works.

Unfortunately my local setup is still not good enough.
I've installed cross-riscv64-gcc14 but it seems that a few more
libraries are necessary, as I get the following compilation errors:

  $ PLATFORM=riscv64 CROSS_COMPILE=riscv64-suse-linux- ./vmtest.sh -- ./test_verifier
  ... kernel compiles ok ...
  ../../../../scripts/sign-file.c:25:10: fatal error: openssl/opensslv.h: No such file or directory
     25 | #include <openssl/opensslv.h>
        |          ^~~~~~~~~~~~~~~~~~~~
  compilation terminated.

  libbpf_internal.h:19:10: fatal error: libelf.h: No such file or directory

  ...

Looks like I won't be able to test this patch-set, unless you have
some writeup on how to create a riscv64 dev environment at hand.
Sorry for the noise.
