root mode การใช้

• As said above, typical lasers are multi-mode and not seeded by a root mode.
• The addition of VT-x has added back the ability to run virtual 8086 mode from x86-64 long mode, but it has to be done by transitioning the ( physical ) processor to VMX root mode and launching a logical ( virtual ) processor itself running in virtual 8086 mode.
• HVM extensions provide additional execution modes, with an explicit distinction between the most-privileged modes used by the hypervisor with access to the real hardware ( called " root mode " in x86 ) and the less-privileged modes used by guest kernels and applications with " hardware " accesses under complete control of the hypervisor ( in x86, known as " non-root mode "; both root and non-root mode have Rings 0 3 ).
