[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [PATCH 01/28] hw: mark secure machines for x86, s390, ppc, arm, loonarch, riscv
The versioned machine types are typically present for use in
virtualization use cases and can be expected to provide a security
barrier. The only exceptions are the m68k versioned machine types
which are only used with TCG. There are also a handful of other
machines declared secure in docs/system/security.rst, notably
the Xen machine variants and microvm.
