Testing or debugging features:
-noisolation Disable seccomp/pledge isolation
-nojit Disable RVJIT (For debug purposes, slow!)
-rvjit_harvard Strict instruction cache flush checks (For guest debug, slow!)
-rvjit_disable_rwx Force W^X JIT heap allocation
-rvjit_force_bmi2 [true/false] Force enable/disable BMI2 x86 extensions
-jitcache 16M Per-core JIT cache size (Scales with guest RAM by default)
-sv48 Enable SV48 MMU pagetable scheme
-sv57 Enable SV57 MMU pagetable scheme
