Linux Kernel Module Cheat

You can select multiple archs and emulators of interest, as for an other command, with:

./test-executables \
  --arch x86_64 \
  --arch aarch64 \
  --emulator gem5 \
  --emulator qemu \
;

You can also test all supported archs and emulators with:

./test-executables \
  --all-archs \
  --all-emulators \
;

This command would run the test four times, using x86_64 and aarch64 with both gem5 and QEMU.

Without those flags, it defaults to just running the default arch and emulator once: x86_64 and qemu.
