Compatibility with Linux kernel

Kernel Modules

Not supported.

libc

• musl: supported
• glibc: not yet supported (it uses some unimplemented Linux features).

System Calls

The type of Implementation Status

• Full: All features are implemented.
• Partial: There're still unimplemented features are left (e.g. rarely used flags).
• Unimplemented: The system call is not implemented at all. It will return ENOSYS.
