Abstract
In some examples, a computing device includes memory including system memory, and a processor in electronic communication with the memory. In some examples, the processor receives a system management interrupt. In some examples, the processor identifies trigger code that triggered the system management interrupt. In some examples, the processor executes code from the system memory when the trigger code is a virtualization program.
Claims15
A computing device, comprising:
- memory including system memory;
- and
- a processor in electronic communication with the memory, wherein the processor is to:
- receive a system management interrupt;
- identify trigger code that triggered the system management interrupt;
- and
- execute code from the system memory when the trigger code is a virtualization program.
4 more elements
An electronic device, comprising:
- memory including system management random access memory (SMRAM);
- and
- a processor in electronic communication with the memory, wherein the processor is to:
- enter system management mode;
- determine whether virtualization is active;
- determine whether the processor is in root mode;
- and
- execute code from the SMRAM when virtualization is active and when the processor is in root mode.
5 more elements
A computing device, comprising:
- a processor to:
- save a processor state when a system management interrupt occurs;
- enter system management mode (SMM);
- identify an active virtual machine extensions (VMX) mode based on the saved processor state;
- and
- execute an SMM operation when the active VMX mode is VMX root mode.
